index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
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>My JSP 'index.jsp' starting page</title>

<body>
   <a href="helloword">helloword</a><br/>
     <a href="springmvc/say">say</a><br/>
    
     <form action="springmvc/testMethod" method="post">
     <input type="submit" value="test"/>
     </form><br/>
      <a href="springmvc/params?username=xiaoming&&age=19">params</a><br/>
</body>
</html>

在WEB_INF 下面创建views文件夹及success.jsp

package com.feiniu.test;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@RequestMapping("/springmvc")
@Controller
public class RequestMappingTest {
   @RequestMapping("/say")
public String say(){
   System.out.println("say!!!!");
   return "success";
}
   @RequestMapping(value="testMethod",method=RequestMethod.POST)
   public String method(){
       System.out.println("testMethod!!!!");
       return "success";
   }

   @RequestMapping(value="params",params={"username","age!=10"})
   public String params(){
       System.out.println("params!!!!");
       return "success";
   }

}
