一、配置web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID"
version="3.1">
<display-name>Spring MVC 01</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class>
<!-- SpringMVC默认加载SpringMVC的配置文件，这个配置文件需要满足以下规则：
命名规则：servlet-name-servlet.xml=====SpringMVC-servlet.xml
路径规则：配置文件必须放在WEB-INFO下面
-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:SpringMVCconfig.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
二、编写SpringMVC配置文件
<?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:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
<!-- 配置处理器映射器:SpringMVC默认处理器映射器
BeanNameUrlHandlerMapping：根据bean(自定义controller bean)的name属性的url去寻找执行类Controller
-->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
<!-- 配置处理器适配器,负责执行Handle(UserController),默认为SimpleControllerHandlerAdapter -->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>
<!-- 配置自定义bean :UserController-->
<bean name="/index.do" class="com.my.controller.UserController"></bean>
<!-- 配置视图解析器：负责解析出真正的物理视图
后台返回逻辑视图:index
解析出真正的物理视图：前缀+逻辑视图+后缀：/WEB-INF/index.jsp
-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix" value="/WEB-INF/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
三、编写Controller
package com.my.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class UserController implements Controller {
@Override
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
// 接受请求，接受参数，验证参数，处理请求
//封装参数，调用业务方法，返回处理结果数据
ModelAndView mv = new ModelAndView();
//给ModelAndView设置数据，可以在页面回显
mv.addObject("name", "Microsoft");
//设置物理视图
//mv.setViewName("/index.jsp");
//设置逻辑视图
mv.setViewName("index");
return mv;
}
}
四、编写视图index.jsp,用JSTL填充数据
<%@ 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></title>
</head>
<body>
<h1>${name }</h1>
</body>
</html>
