hello.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">        <title>哈哈哈哈哈哈哈</title>    <meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">-->  </head>    <body>    HELLO WORLD  </body></html>

配置Controller

HelloController.java

package com.raven.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.raven.model.Person;@Controllerpublic class HelloController {@RequestMapping("/hello1")public String hello1(Person person){System.out.println("---------------------------------");System.out.println(person.getName());System.out.println(person.getAge());System.out.println("---------------------------------");return "hello";}}

配置拦截器

GInterception.java

</pre><pre name="code" class="java">package com.raven.interception;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.ModelAndView;public class GInterception implements HandlerInterceptor {@Overridepublic void afterCompletion(HttpServletRequest arg0,HttpServletResponse arg1, Object arg2, Exception arg3)throws Exception {// TODO Auto-generated method stub}@Overridepublic void postHandle(HttpServletRequest arg0, HttpServletResponse arg1,Object arg2, ModelAndView arg3) throws Exception {System.out.println("after");}@Overridepublic boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1,Object arg2) throws Exception {System.out.println("before");return true;}}

JavaBean

Person.java

package com.raven.model;public class Person {private String name;private String age;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAge() {return age;}public void setAge(String age) {this.age = age;}}
