- Create the file /WEB-INF/web.xml
-
- Create the file /WEB-INF/HelloWorld-servlet.xml
123456789101112131415161718192021<?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/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><context:component-scan base-package="it.helloworld.controller" /><bean id="viewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix"><value>/WEB-INF/views/</value></property><property name="suffix"><value>.jsp</value></property></bean></beans>
- Create the file /WEB-INF/HelloWorld-servlet.xml
-
- Create the file index.jsp in the application root
12345678910111213<%@page contentType="text/html" 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>Welcome Page</title></head><body><jsp:forward page="helloWorld.html" /></body></html>
- Create the file index.jsp in the application root
-
- Create the directory /WEB-INF/views and the file /WEB-INF/views/helloWorld.jsp
12345678910111213<%@page contentType="text/html" 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>JSP Page</title></head><body><h1>Hello World!</h1></body></html>
- Create the directory /WEB-INF/views and the file /WEB-INF/views/helloWorld.jsp
-
- Create the file /WEB-INF/classes/it/helloworld/controller/HelloWorldController.java
1234567891011121314package it.helloworld.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;@Controllerpublic class HelloWorldController {@RequestMapping(value={"/index", "/helloWorld"})public ModelAndView helloWorld() {return new ModelAndView("helloWorld");}}
- Create the file /WEB-INF/classes/it/helloworld/controller/HelloWorldController.java
