8.21 SpringMVC快速如门

 controller中的代码
 1 package com.neuedu.controller;
 2 
 3 import org.springframework.stereotype.Controller;
 4 import org.springframework.web.bind.annotation.PathVariable;
 5 import org.springframework.web.bind.annotation.RequestMapping;
 6 import org.springframework.web.bind.annotation.RequestMethod;
 7 import org.springframework.web.bind.annotation.RequestParam;
 8 import org.springframework.web.bind.annotation.ResponseBody;
 9 
10 @Controller
11 public class AController {
12     private static String SUCCESS="success";
13     
14     
用于测试是否能正常运行
15     @RequestMapping("/sayHello")
16     public String sayHello(){
17         return SUCCESS;
18     }
19

20     @RequestMapping(value="/order/{id}" ,method=RequestMethod.GET)
21     public String getOrderById1(@PathVariable(value="id") Integer id){
22         System.out.println(id);
23         return SUCCESS;
24     }
25     
测试post请求
26     @RequestMapping(value="/order/{id}" ,method=RequestMethod.POST)
27     public String getOrderById2(@PathVariable(value="id") Integer id){
28         System.out.println(id);
29         return SUCCESS;
30     }
31     
测试put
32     @RequestMapping(value="/order/{id}" ,method=RequestMethod.PUT)
33     @ResponseBody()
34     public String getOrderById3(@PathVariable(value="id") Integer id){
35         System.out.println(id);
36         return SUCCESS;
37     }
38     
测试delete
39     @RequestMapping(value="/order/{id}" ,method=RequestMethod.DELETE)
40     @ResponseBody()
41     public String getOrderById4(@PathVariable(value="id") Integer id){
42         System.out.println(id);
43         return SUCCESS;
44     }
45     
测试@RequestParam得到jsp中的值
46     @RequestMapping(value="/testRequstPamarm" ,method=RequestMethod.POST)
47     public String testRequstPamarm(@RequestParam("username") String name,@RequestParam("pwd") String pwd){
48         System.out.println("用户名："+name);
49         System.out.println("密码："+pwd);
50         return SUCCESS;
51     }
53 }

 2     <a href="${pageContext.request.contextPath}/sayHello">Hello!</a>
 3     <br>
测试get
 4     <a href="${pageContext.request.contextPath}/order/1">测试GET</a>
 5     <br>
测试post请求
 6     <form action="${pageContext.request.contextPath}/order/2" method="post">
 7         <input type="submit" value="提交">
 8     </form>
 9     <br>
测试put
10     <form action="${pageContext.request.contextPath}/order/3" method="post">
11         <input type="hidden" name="_method" value="put">
12         <input type="submit" value="提交">
13     </form>
14     <br>
测试delete
15     <form action="${pageContext.request.contextPath}/order/4" method="post">

17         <input type="submit" value="提交">
18     </form>
19     <br>
测试@RequestParam得到表单中的值
20     <form action="${pageContext.request.contextPath}/testRequstPamarm" method="post">
21         用户名：<input type="text" name="username">
22         <br>
23         密  码：<input type="text" name="pwd">
24         <br>
25         <input type="submit" value="提交">
