一、程序结构
二、设置步骤
１、创建一个web项目mvc1，拷贝jar包到lib文件夹中。下载地址：http://pan.baidu.com/s/1i4ty2UT
2、配置web.xml文件：
<?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>mvc1</display-name>
<welcome-file-list>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<!--配置servlet -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- 配置servlet映射 -->
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
3、配置springMVC-servlet.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
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-4.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd">
<!-- 视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
4、编写代码HelloWorldController：
package cn.shxy.web.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
/**
* controller
* @author John
*
*/
public class HelloWorldController implements Controller{
@Override
public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
System.out.println("---Hello World!---");
return new ModelAndView("/index");
}
}
5、创建index.jsp文件：
<%@ 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>主页</title>
</head>
<body>
欢迎使用SpringMVC!
</body>
</html>
6、在springMVC-servlet.xml文件中配置controller到springmvc：
<!-- 配置controller -->
<bean name="/test/helloworld" class="cn.shxy.web.controller.HelloWorldController" />
7、测试，地址：http://localhost:8080/mvc1/test/helloworld
