Step 1: Configure Dispatcher servlet in web.xml

<!DOCTYPE web-app PUBLIC

 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

 "http://java.sun.com/dtd/web-app_2_3.dtd" >


<web-app>

  <display-name>Archetype Created Web Application</display-name>

 <!--  Configure  disptacher servlet -->

 

 <servlet>

  <servlet-name>spring</servlet-name>

  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

 </servlet>

 

 <servlet-mapping>

 <servlet-name>spring</servlet-name>

 <url-pattern>/</url-pattern>

 </servlet-mapping>

 

</web-app>


2. Create Spring Configuration file spring-servlet.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"

     xmlns:p="http://www.springframework.org/schema/p"

    xmlns:context="http://www.springframework.org/schema/context"

    xsi:schemaLocation="http://www.springframework.org/schema/beans 

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 

http://www.springframework.org/schema/context 

http://www.springframework.org/schema/context/spring-context-3.0.xsd">


 <context:component-scan base-package="springmvc.controller"></context:component-scan>

 

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" name="viewResolver">

<property name="prefix" value="/WEB-INF/views/"/>

<property name="suffix" value=".jsp"/>


</bean>

</beans>


3. Configure view resolver

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" name="viewResolver">

<property name="prefix" value="/WEB-INF/views/"/>

<property name="suffix" value=".jsp"/>


</bean>


4.Create Controller


package springmvc.controller;


import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;


@Controller

public class HomeController {


@RequestMapping("/home")

public String home()

{

System.out.print("hei");

return "index";

}

@RequestMapping("/about")

public String about()

{

return "about";

}

}


5. Create index.jsp inside webapp/WEB-INF/views


<%@ page language="java" contentType="text/html; charset=UTF-8"

    pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

<head>

<meta charset="UTF-8">

<title>Home</title>

</head>

<body>

<h1>

Configured

</h1>

</body>

</html>
