Spring MVC Tutorial – Hibernate Integration

with 21 comments

After a long gap…

For introduction to Spring MVC in particular, see Spring MVC Tutorial and Spring MVC Tutorial 2.

The project done in STS can be downloaded from my Box.net account. The project libraries you will have to edit to match your setup.

Along with learning to integrate Hibernate, I’ll be introducing some new pieces of Spring MVC.

For this installment, I am using the following:

  1. JDK 6 update 16
  2. Tomcat 6.0.20
  3. SpringSource Tool Suite 2.2.0 as my IDE
  4. MySQL 5.1
  5. Spring Framework 2.5.6.SEC01 (the bundle with all dependencies included so that I don’t have to look for jars here and there)
  6. JSTL 1.2 (from jstl.dev.java.net)
  7. Hibernate Distribution 3.3.2.GA
  8. Hibernate Annotations 3.4.0.GA
  9. log4j 1.2.15
  10. slf4j 1.5.8
  11. JDBC Driver – MySQL Connector/J 5.1.6

The project is named ‘ibank’ – an Internet portal for bank customers. We’ll be doing customer registration only.

Without any fuss, let’s start.

Setup the Initial Project in STS

  1. Start STS
  2. Create a Dynamic Web Project from File>New>Other
  3. Name the project ‘ibank’
  4. Choose the target runtime – the server on which you’ll be deploying. Create one if already not available.
  5. Keep everything else default (the source, class and web content directories)
  6. After the project is created, right-click on the root node and choose Spring Tools>Add Spring Project Nature

Add the necessary libraries. Following jars will be required:

JAR Source
spring.jar, commons-logging.jar,
commons-dbcp.jar, commons-pool.jar		 Spring Framework
jstl-api-1.2.jar, jstl-impl-1.2.jar jstl.dev.java.net
hibernate3.jar, antlr-2.7.6.jar, commons-collections-3.1.jar
dom4j-1.6.1.jar, javassist-3.9.0.GA.jar, jta-1.1.jar		 Hibernate Core Distribution
hibernate-annotations.jar, ejb3-persistence.jar
hibernate-commons-annotations.jar		 Hibernate Annotations
log4j-1.2.15.jar Log4J
slf4j-api-1.5.8.jar, slf4j-log4j12-1.5.8.jar SLF4J
mysql-connector-java-5.1.6-bin.jar MySQL Connector/J

Happy hunting!

Configure web.xml Spring MVC

Rewrite the auto-generated web.xml with the following (for explanations, see my first Spring MVC Tutorial):

<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xmlns=”http://java.sun.com/xml/ns/javaee” xmlns:web=”http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd”
xsi:schemaLocation=”http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd”
id=”WebApp_ID” version=”2.5″>

<display-name>ibank</display-name>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/ibank-service.xml
/WEB-INF/ibank-persistence.xml
</param-value>
</context-param>

<servlet>
<servlet-name>ibank</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>ibank</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

Write the Starting Page

Create a new JSP file in the WebContent folder, STS/Eclipse copies everything from this folder to the root of your web application deployment. To do so,

  1. Right-click WebContent in the project explorer and then New>JSP
  2. Name it index.jsp and accept all defaults
  3. Clean up the generated mess after the @page tag and add just one redirect line:

<%@ page language=”java” contentType=”text/html; charset=UTF-8″
pageEncoding=”UTF-8″%>
<% response.sendRedirect(“home.htm”); %>

Controller and View for home.htm

We need to write a controller for dealing with /index.htm as redirected by index.jsp. After writing the controller, we have to map it in ibank-servlet.xml and also write a JSP that will be used as the returned view.

First, the Controller

The IndexController is a very simple one that records the system date and passes control to DispatcherServlet with the view name ‘home’.

package org.himu.ibank.controller;

import java.util.Calendar;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HomePageController extends AbstractController {

@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {

// time at the server
Date today = Calendar.getInstance().getTime();
ModelAndView mv = new ModelAndView(“home”);
mv.addObject(“today”, today);
return mv;
}
}

Creating the Spring Bean Definition Files

Before we configure the beans in Spring we create all three bean configuration files and tell the IDE to treat them under a single set.

  1. In Project Explorer, right-click Java Resources: src and then click New>Other, select Spring Bean Configuration File
  2. When prompted, choose the WebContent>WEB-INF folder, give the exact name ‘ibank-servlet.xml’ (ibank is the DispatcherServlet’s name in web.xml) and click Next
  3. In the next dialog, beans namespace is pre-selected – click on it and be sure to check the 2.5 version of the XSD, click Finish
  4. Create ibank-service.xml and ibank-persistence.xml in a similar fashion
  5. In Project Explorer, expand Spring Elements, right-click Beans and choose Properties. The three files created should be shown in the Config Files tab
  6. Go to Config Sets tab and click the New button
  7. Give a name of your choice (I chose ibank-beans), click Select All and then OK
  8. Close the Properties dialog

Mapping the Controller and View

Now we make the Spring MVC related configurations in ibank-servlet.xml. First we setup the controller mapping using SimpleUrlHandlerMapping (which will be used for other controllers as well) and the setup the view resolver InternalResourceViewResolver which takes any view name and generates the corresponding JSP page name.

<?xml version=”1.0″ encoding=”UTF-8″?>
<beans xmlns=”http://www.springframework.org/schema/beans”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd”>

<bean id=”simpleUrlMapping” class=”org.springframework.web.servlet.handler.SimpleUrlHandlerMapping”>
<property name=”mappings”>
<props>
<prop key=”/home.htm”>homePageController</prop>
</props>
</property>
</bean>

<bean id=”viewResolver” class=”org.springframework.web.servlet.view.InternalResourceViewResolver”>
<property name=”prefix” value=”/WEB-INF/jsp/”/>
<property name=”suffix” value=”.jsp”/>
</bean>

<bean id=”homePageController” class=”org.himu.ibank.controller.HomePageController”/>

</beans>

Writing the View JSP

We’ll write all your JSP’s under WEB-INF/jsp folder as indicated in the view resolver above. So, create a new folder names jsp under WEB-INF and then create a new JSP file names home.jsp:

<%@ page language=”java” contentType=”text/html; charset=UTF-8″
pageEncoding=”UTF-8″%>
<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN” “http://www.w3.org/TR/html4/loose.dtd”>
<html>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″>
<title>iBank – Home</title>
</head>
<body>
<h1 align=”center”>Welcome to iBank</h1>
<h2 align=”center”>Your Online Bank Portal</h2>
<p align=”center”>
Today is ${today}.<br/>
<a href=”<%=request.getContextPath()%>/adminhome.htm”>Administration Site</a>
</p>
</body>
</html>

Test Running the Application

If a Tomcat runtime is not configured with the IDE then

  1. Go to Window>Preferences, expand Server node in the tree on the left and select Runtime Environments
  2. Click Add and choose your Tomcat version (shouldn’t be less than 5.5), click Next
  3. If the IDE doesn’t auto-detect your CATALINA_HOME (or you haven’t defined any) then Browse and point to the installation folder, click Finish
  4. Go to Window>Show View>Servers
  5. Right-click on the Servers panel and choose New>Server
  6. Select the server type and check if the server runtime environment shows the one created in steps 1-3
  7. Click Next
  8. At this point, the IDE will give you an option to make your project available to the created server
  9. Select your application and click Add, then click Finish

If your controller shows errors with the HttpServlet… classes

  1. Right-click your project root, select Build Path>Configure Build Path
  2. Select the Libraries tab
  3. Click Add Library, then choose Server Runtime and select your Tomcat server

If Tomcat is already configured in your IDE then

  1. Open the Servers panel (Window>Show View>Servers)
  2. Right-click your server and choose Add and Remove
  3. Add your application and click Finish

Finally, to run your application, right-click on the server and click Publish. Then start the server by right-click and Start.

Fire up your browser and point to http://localhost:8080/ibank.

Setting Up the Admin Site

I’ll be doing some fun stuff here to make the site look a bit better. Some CSS techniques are applied (not my invention).

  1. Under WEB-INF/jsp, create a new folder named admin
  2. Create three JSP files: admin.jsp, menu.jsp, and footer.jsp
  3. Under WebContent folder, create a new CSS file names master.css
  4. Edit the files so that they look similar to the following

master.css

@CHARSET “UTF-8″;

html, body {
margin: 0; padding: 0; height: 100%; background: #FFFFFF;
}

#mask {
position: relative; min-height: 100%; margin-bottom: -25px;
}

#header {
background: #006699; width: 100%; height: 100px; overflow: hidden;
}

#content-wrapper {
float: left; width: 100%; background: #DDEEFF; overflow: hidden;
position: relative; min-height: 100%;
border-color: black; border-style: solid; border-width: thin;
}

#leftcol-wrapper {
float: left; width: 100%; background: #6699CC;
position: relative; right: 80%; min-height: 100%;
border-color: black; border-style: solid; border-width: thin;
}

#leftcol {
float: left; width: 18%; position: relative;
left: 81%; padding-bottom: 25px;
}

#content {
float: left; width: 78%; position: relative;
left: 83%; padding-bottom: 25px; overflow: hidden;
}

#footer {
background: #444444; color: #FFFFFF; position: relative;
overflow: hidden; width: 100%; bottom: 0; height: 25px;
}

#clearfooter {
height: 25px; clear: both;
}

menu.jsp

<%@ page language=”java” contentType=”text/html; charset=UTF-8″
pageEncoding=”UTF-8″%>
<ul>
<li><a href=”<%=request.getContextPath()%>/adminhome.htm”>Admin Home</a></li>

Configuring Spring MVC

After the .jsp and .css files are in place, add the following mapping in ibank-servlet.xml under simpleUrlMapping bean (The /adminhome.htm is referred to in home.jsp):

<prop key=”/adminhome.htm”>adminHomePageController</prop>

We won’t be writing the adminHomePageController implementation. Instead, we’ll be using one of Spring MVC’s built-in controller as there is no processing involved from our part. Add this in ibank-servlet.xml:

<bean id=”adminHomePageController” class=”org.springframework.web.servlet.mvc.ParameterizableViewController”>
<property name=”viewName” value=”admin/admin”/>
</bean>

The admin/admin view name get mapped to /WEB-INF/jsp/admin/admin.jsp by the view resolver.

Go, test the new admin page.

Hibernate – Configuration Basics

This is not a tutorial about Hibernate. So don’t expect even a decent introduction!

The starting point of a Hibernate setup is the SessionFactory. SessionFactory can be configured using an XML file or using Annotations or even raw programmatic manipulation. For the traditional XML configuration using .hbm.xml mapping documents, you instantiate it using the following code:

SessionFactory sf = new Configuration().configure().buildSessionFactory();

For the annotation-supported SessionFactory (supports both EJB3 and Hibernate-specific annotation), use the following:

SessionFactory sf = new AnnotationConfiguration().configure().buildSessionFactory();

In both cases, hibernate.cfg.xml – the core hibernate configuration file – must be available in the classpath.

A typical hibernate.cfg.xml file for using mapping documents is as follows (adapted from Hibernate docs):

<?xml version=’1.0′ encoding=’utf-8′?>
<!DOCTYPE hibernate-configuration PUBLIC
“-//Hibernate/Hibernate Configuration DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd”>

<hibernate-configuration>

<session-factory>

<!– Database connection settings –>
<property name=”connection.driver_class”>org.hsqldb.jdbcDriver</property>
<property name=”connection.url”>jdbc:hsqldb:hsql://localhost</property>
<property name=”connection.username”>sa</property>
<property name=”connection.password”></property>

<!– SQL dialect –>
<property name=”dialect”>org.hibernate.dialect.HSQLDialect</property>

<!– Enable Hibernate’s automatic session context management –>
<property name=”current_session_context_class”>thread</property>

<mapping resource=”org/hibernate/tutorial/domain/Event.hbm.xml”/>

</session-factory>

</hibernate-configuration>

A annotation-based configuration is similar to the following (from Hibernate docs):

<?xml version=’1.0′ encoding=’utf-8′?>

<!DOCTYPE hibernate-configuration PUBLIC
“-//Hibernate/Hibernate Configuration DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd”>

<hibernate-configuration>
<session-factory>
<mapping package=”test.animals”/>
<mapping class=”test.Flight”/>
<mapping class=”test.Sky”/>
<mapping class=”test.Person”/>
<mapping class=”test.animals.Dog”/>
<mapping resource=”test/animals/orm.xml”/>
</session-factory>
</hibernate-configuration>

Now let’s look at a typical use of Hibernate API (again from Hibernate docs):

private void createAndStoreEvent(String title, Date theDate) {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();

Event theEvent = new Event();
theEvent.setTitle(title);
theEvent.setDate(theDate);
session.save(theEvent);

session.getTransaction().commit();
}

With Spring in control, we’ll be eliminating a lot of this!

Hibernate in Spring

The configuration information will be places in ibank-persistence.xml just to separate the persistence-related information. Here is the basic outline:

  1. Take out the database connection information out of Hibernate and manage it through Spring.
  2. Configure Hibernate SessionFactory using Spring’s built-in support, eliminating the need for a hibernate.cfg.xml.

Edit ibank-persistence.xml so that it looks like the following:

<?xml version=”1.0″ encoding=”UTF-8″?>
<beans xmlns=”http://www.springframework.org/schema/beans”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd”>

<bean id=”dataSource” class=”org.apache.commons.dbcp.BasicDataSource”>
<property name=”driverClassName” value=”com.mysql.jdbc.Driver”/>
<property name=”url” value=”jdbc:mysql://localhost/ibankdb”/>
<property name=”username” value=”ibankusr”/>
<property name=”password” value=”pass123″/>
<!– connection pooling details –>
<property name=”initialSize” value=”1″/>
<property name=”maxActive” value=”5″/>
</bean>
<bean id=”sessionFactory”
class=”org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean”>
<property name=”dataSource” ref=”dataSource”/>
<property name=”hibernateProperties”>
<props>4
<prop key=”hibernate.dialect”>org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<prop key=”hibernate.show_sql”>true</prop>
<prop key=”hibernate.hbm2ddl.auto”>update</prop>
</props>
</property>
<property name=”annotatedClasses”>
<list>
<!– all the annotation entity classes –>
</list>
</property>
</bean>
</beans>

The dataSource bean defines a DBCP connection pool with the necessary info to connect to a MySQL database named ibankdb on the localhost. The sessionFactory bean is our Hibernate SessionFactory configured entirely through Spring. Note that the annotatedClasses list is empty as we haven’t defined any entity classes to be persisted. We’ll add to it in due time.

Defining the Persistence and DAO (Data Access Object) Classes

We want to register new customers and then approve them in our system. Create a Customer class under org.himu.ibank.domain:

package org.himu.ibank.domain;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class Customer {

public static int STATUS_REGISTERED = 0;
public static int STATUS_ACTIVE = 1;
public static int STATUS_INACTIVE = 2;

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name=”CUST_ID”)
private Long id;

@Column(name=”USER_ID”, unique=true)
private String userId;
@Column(name=”USER_PWD”)
private String password;
@Column
private String firstName;
@Column
private String lastName;
@Column
private String email;
@Column
private int status;

public Customer() {
id = null;
status = STATUS_REGISTERED;
}

// getters and setters

}

This is not a Hibernate tutorial. But still some discussion. We must tell Hibernate that we want a class/POJO to be treated as persistent – using the @Entity annotation. Each field to be mapped to the database needs to be marked with the @Column annotation except the primary key which is annotated with @Id. The additional @Column annotation for the id field is used to explicitly map it to a column name of our choice (CUST_ID). The unique attribute for userId is set to true so that a unique index for it is used. The @GeneratedValue annotation tells the persistence provider to choose the best primary key generation technique for the underlying database – an auto-increment integer for MySQL.

Instead of creating a DAO class directly, we use an interface for segregation of specification and implementation. This way we will be able to change the implemenation to JPA or some other ORM in the future – without affecting our client code. Following is the interface CustomerDao:

package org.himu.ibank.dao;

import java.util.List;

import org.himu.ibank.domain.Customer;

public interface CustomerDao {

Long addNew(Customer c);
void delete(Customer c);
void update(Customer c);
Customer findById(Long id);
Customer findByUserId(String uid);
List<Customer> listAll();
List<Customer> listAll(int startPage, int pageSize);
List<Customer> listByExample(Customer c);
List<Customer> listByExample(Customer c, int startPage, int pageSize);
}

Following is the implementation class, HibernateCustomerDao:

package org.himu.ibank.dao;

import java.util.List;

import org.hibernate.criterion.DetachedCriteria;
import org.hibernate.criterion.Order;
import org.himu.ibank.domain.Customer;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class HibernateCustomerDao extends HibernateDaoSupport implements
CustomerDao {

@Override
public Long addNew(Customer c) {
return (Long) getHibernateTemplate().save(c);
}

@Override
public void delete(Customer c) {
getHibernateTemplate().delete(c);
}

@Override
public void update(Customer c) {
getHibernateTemplate().update(c);
}

@Override
public Customer findById(Long id) {
return (Customer) getHibernateTemplate().get(Customer.class, id);
}

@SuppressWarnings(“unchecked”)
@Override
public Customer findByUserId(String uid) {
List<Customer> clist =  getHibernateTemplate().find(“from Customer c where c.userId = ?”, uid);
if (clist.isEmpty())
return null;
else
return clist.get(0);
}

@SuppressWarnings(“unchecked”)
@Override
public List<Customer> listAll() {
return getHibernateTemplate().find(“from Customer c”);
}

@SuppressWarnings(“unchecked”)
@Override
public List<Customer> listAll(int startPage, int pageSize) {
DetachedCriteria criteria = DetachedCriteria.forClass(Customer.class);
criteria.addOrder(Order.asc(“id”));
return getHibernateTemplate().findByCriteria(criteria, startPage, pageSize);
}

@SuppressWarnings(“unchecked”)
@Override
public List<Customer> listByExample(Customer c) {
return getHibernateTemplate().findByExample(c);
}

@SuppressWarnings(“unchecked”)
@Override
public List<Customer> listByExample(Customer c, int startPage, int pageSize) {
return getHibernateTemplate().findByExample(c, startPage, startPage);
}

}

The beauty of using Spring springs to life is this case. We’re extending our DAO from HibernateDaoSupport which encapsulates all the gory details of dealing with Hibernate directly. The magic comes through the use of a HibernateTemplate which we get a reference to using getHibernateTemplate(). As you can see, HibernateTemplate gives us convenient methods to do all the common things of Hibernate. Still we need to do some specifics:

  • findByUserId() uses an HQL (Hibernate Query Language) statement to filter results by userId and not the primary key (id in this case).
  • listAll() method uses the simplest select all statement.
  • listAll(startPage, pageSize) uses DetachedCriteria (a Spring gift) for paging support.
  • listByExample(…) methods use Hibernates query-by-example (QBE) facility.

Once the classes are ready, we configure them in Spring in ibank-persistence.xml. The data source and session factory are already there. We add our domain class Customer to the list of annotated classes. And we configure our DAO as well.

<bean id=”sessionFactory”
…
<property name=”annotatedClasses”>
<list>
<value>org.himu.ibank.domain.Customer</value>
</list>
</property>
</bean>
<bean id=”customerDao”
class=”org.himu.ibank.dao.HibernateCustomerDao”>
<property name=”sessionFactory” ref=”sessionFactory”/>
</bean>
</beans>

Defining the Service Classes

It’s no use writing the domain and DAO classes only. We need a service class for interacting with the UI as well. As usual we separate the interface and implementation. First, the interface:

package org.himu.ibank.service;

import java.util.List;

import org.himu.ibank.domain.Customer;

public interface CustomerRegistrationService {

Long registerCustomer(Customer c);
void authorizeCustomer(Customer c);
List<Customer> getUnauthorizedCustomers(int startPage, int pageSize);
List<Customer> getCustomers(int startPage, int pageSize);
List<Customer> getAllCustomers(int startPage, int pageSize);
}

Then, we write the actual implementation:

package org.himu.ibank.service;

import java.util.List;

import org.himu.ibank.dao.CustomerDao;
import org.himu.ibank.domain.Customer;

public class StandardCustomerRegistrationService implements
CustomerRegistrationService {

private CustomerDao custDao;
public void setCustDao(CustomerDao custDao) {
this.custDao = custDao;
}

@Override
public Long registerCustomer(Customer c) {
return custDao.addNew(c);
}

@Override
public void authorizeCustomer(Customer c) {
if (c.getStatus() == Customer.STATUS_REGISTERED) {
c.setStatus(Customer.STATUS_ACTIVE);
custDao.update(c);
// … mailer code for notifying customer …
}
}

/**
* Get registered but unauthorized customers using optional paging.
*
* @param startPage Starting page number, first page is 0
* @param pageSize Size of a single page, <=0 means no paging
*/
@Override
public List<Customer> getUnauthorizedCustomers(int startPage, int pageSize) {
Customer c = new Customer();
c.setStatus(Customer.STATUS_REGISTERED);
return custDao.listByExample(c, startPage, pageSize);
}

/**
* Get registered and authorized customers using optional paging.
*
* @param startPage Starting page number, first page is 0
* @param pageSize Size of a single page, <=0 means no paging
*/
@Override
public List<Customer> getCustomers(int startPage, int pageSize) {
Customer c = new Customer();
c.setStatus(Customer.STATUS_ACTIVE);
return custDao.listByExample(c, startPage, pageSize);
}

@Override
public List<Customer> getAllCustomers(int startPage, int pageSize) {
return custDao.listAll(startPage, pageSize);
}
}

Now we need to tell Spring about our service class in ibank-service.xml:

<?xml version=”1.0″ encoding=”UTF-8″?>
<beans xmlns=”http://www.springframework.org/schema/beans”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd”>

<bean id=”customerRegService”
class=”org.himu.ibank.service.StandardCustomerRegistrationService”>
<property name=”custDao” ref=”customerDao”/>
</bean>
</beans>

New Customer Registration

We have our domain, DAO, and service classes written and configured in Spring. Now we’ll write our Spring MVC things for registering a new customer. Here’s the outline:

  1. User clicks on new customer registration link
  2. System presents new customer input page
  3. User fills in the details and submits
  4. System verifies data – omitted from this tutorial
  5. System saves the new customer and displays summary

We will first write the controller.

NewCustomerController.java

package org.himu.ibank.controller;

import java.util.HashMap;
import java.util.Map;

import org.himu.ibank.domain.Customer;
import org.himu.ibank.service.CustomerRegistrationService;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;

public class NewCustomerController extends SimpleFormController {

private CustomerRegistrationService custRegService;

public void setCustRegService(CustomerRegistrationService custRegService) {
this.custRegService = custRegService;
}

@Override
protected ModelAndView onSubmit(Object command) throws Exception {
Customer c = (Customer) command;
custRegService.registerCustomer(c);
Map<Object, Object> map = new HashMap<Object, Object>();
map.put(getCommandName(), c);
return new ModelAndView(getSuccessView(), map);
}
}

We could have overridden doSubmitAction() for in NewCustomerController but I just wanted to show you how to use the model and view names provided in the configuraiton file (shown later).

admin/newcustomer.jsp

Customer registration is an administration thing. We’ve already defined a nice looking (!) template in admin.jsp which we want to re-use. If we had used Tiles then that would have been taken care of. But we’re not using Tiles. So, for now, lets make a copy of the admin.jsp in STS by selecting it in the Project Explorer, then pressing Ctrl+C and Ctrl+V in sequence. STS understands and prompts you to provide a name for the new copy. Name it newcustomer.jsp and modify the contents of the ‘mask’ div as follows:

<div id=”mask”>
<div id=”header”>
<h1>iBank – Register New Customer</h1>
</div>
<div id=”content-wrapper”>
<div id=”leftcol-wrapper”>
<div id=”leftcol”><jsp:include page=”menu.jsp”/></div>
<div id=”content”>
<form:form method=”post” commandName=”customer”>
<form:errors path=”*”/>
<!– userid, password, fname, lname, email, status –>
<table>
<tr><td>User ID</td><td><form:input path=”userId”/></td></tr>
<tr><td>Password</td><td><form:password path=”password”/></td></tr>
<tr><td>First Name</td><td><form:input path=”firstName”/></td></tr>
<tr><td>Last Name</td><td><form:input path=”lastName”/></td></tr>
<tr><td>E-mail</td><td><form:input path=”email”/></td></tr>
<tr><td>&nbsp;</td><td><input type=”submit”/></td></tr>
</table>
</form:form>
</div>
</div>
</div>
<div id=clearfooter”></div>
</div>

admin/newcustomer-success.jsp

Create the success view JSP by copying admin.jsp and modifying as follows:

<div id=”mask”>
<div id=”header”>
<h1>iBank – New Customer ${customer.userId} Registered Successfully</h1>;
</div>
<div id=”content-wrapper”>
<div id=”leftcol-wrapper”>
<div id=”leftcol”><jsp:include page=”menu.jsp”/></div>
<div id=”content”>
<table>
<tr><td>System ID</td><td>${customer.id}</td></tr>
<tr><td>User ID</td><td>${customer.userId}</td></tr>
<tr><td>Password</td><td><i>secret</i></td></tr>
<tr><td>First Name</td><td>${customer.firstName}</td></tr>
<tr><td>Last Name</td><td>${customer.lastName}</td></tr>
<tr><td>E-mail</td><td>${customer.email}</td></tr>
</table>
<a href=”<%=request.getContextPath()%>/createcust.htm”>Register Another Customer</a>
</div>
</div>
</div>
<div id=clearfooter”></div>
</div>

Binding the Controller and Views

Now that we have our files ready, we can configure them in ibank-servlet.xml. Following is the bean entry for NewCustomerController:

<bean id=”newCustomerController” class=”org.himu.ibank.controller.NewCustomerController”>
<property name=”custRegService” ref=”customerRegService”/>
<property name=”formView” value=”admin/newcustomer”/>
<property name=”successView” value=”admin/newcustomer-success”/>
<property name=”commandName” value=”customer”/>
<property name=”commandClass” value=”org.himu.ibank.domain.Customer”/>
</bean>

We also must not forget the url mapping under simpleUrlMapping:

<prop key=”/createcust.htm”>newCustomerController</prop>

The Project Structure

We’re done for our first Hibernate test. Following is a snapshot of the STS project structure:

Spring MVC - Hibernate STS Project

That’s It!

I feel this entry is quite long. But I couldn’t help but detail all the steps that I’ve gone through so that anyone can recreate the whole thing from scratch.

I’ll be expanding the project to contain a Customer browsing and authorization part. Another blog entry for that. Hope this was useful to you. Comments welcome!

  1. Sorry guys! There is a mistake in HibernateCustomerDao above (as well as in the source code download).

    Instead of

    listByExample(startPage, pageSize)
    or
    listByExample(startPage, startPage)

    the code should be

    listByExample(startPage * pageSize, pageSize)

      675796 [http-9999-2] WARN servlet.PageNotFound – No mapping for [/ibank/viewcustlist.htm] in DispatcherServlet with name ‘ibank’

  4. Himu,

    This is the great article and helped me a lot in inderstanding Spring related concepts in my first Spring based project.

    By the way when are you going to have article on “Customer browsing and authorization part”. Please publish it as early as possible. I am very excited to see that.

    • hello ravi,

      you don’t need a separate script for the db. it is automatically created by Hibernate. The trick is in

      <prop key=”hibernate.hbm2ddl.auto”>update</prop>

  7. Thanks for the tutorial, your tutorial really help me (newbie) understand more about spring/hibernate. One question though; How do I put the hibernate and the persistence to connect to the oracle db?

    August 12, 2010 at 10:31 pm

    Reply

    • First of all you need the appropriate oracle JDBC driver library (e.g. ojdbc14.jar).
      After that, in ibank-persistence.xml, change the dataSource bean definition to use the Oracle driver (oracle.jdbc.OracleDriver) and corresponding URL (jdbc:oracle:thin:@<server>:<port>:<sid>).
      Next, change the Hibernate dialect to org.hibernate.dialect.Oracle10gDialect (or whatever appropriate).

      The same goes for any database.
