Directory Structure of Spring MVC application is given below:

step 1:

Create index.jsp file

 

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>MultiActionController</title>
</head>
<body>
<h4>MultiActionController Example</h4>
<h5><a href="actionOne.bean">Action One</a></h5>
<h5><a href="actionTwo.bean">Action Two</a></h5>
<h5><a href="actionThree.bean">Action Three</a></h5>
</body>
</html>

step 2:

Create web.xml file

<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>Spring MVC Application</display-name>
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.bean</url-pattern>
</servlet-mapping>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/dispatcher-servlet.xml
</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

step 3:

Create dispatcher-servlet.xml file

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema
/context/spring-context-2.5.xsd">
<bean id="viewResolver"
class="org.springframework.web.servlet.
view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/pages/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
<bean name="/*.bean"
class="com.r4r.MultiActionControllerExample"/>
</beans>

step 4:

Create MultiActionControllerExample.java file

package com.r4r;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.
multiaction.MultiActionController;
public class MultiActionControllerExample 
extends MultiActionController {
public ModelAndView actionOne(HttpServletRequest request,
HttpServletResponse response)throws Exception{
ModelAndView model=new ModelAndView("page");
model.addObject("msg","Action One.");
return model;
}
public ModelAndView actionTwo(HttpServletRequest request,
HttpServletResponse response)throws Exception{
ModelAndView model=new ModelAndView("page");
model.addObject("msg","Action Two.");
return model;
}
public ModelAndView actionThree(HttpServletRequest request,
HttpServletResponse response)throws Exception{
ModelAndView model=new ModelAndView("page");
model.addObject("msg","Action Three.");
return model;
	}
}

step 5:

Create page.jsp file

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<title>MultiActionController Example</title>
</head>
<body>
<h3>MultiActionController Example in Spring MVC</h3>
