Spring MVC请求到处理方法注解配置的几种方式

• @RequestMapping

这个是最常用的注解，可以配置在类上，也可以配置在方法上，两个一起作用组成方法能够响应的请求路径，举例如下

 1 package org.zln.myWeb.controller;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.stereotype.Controller;
 5 import org.springframework.web.bind.annotation.*;
 6 import org.zln.myWeb.domain.T00_User;
 7 import org.zln.myWeb.service.T00_UserService;
 8 
 9 import java.util.HashMap;
10 import java.util.Map;
11 
12 /**
13  * Created by sherry on 16/8/6.
14  */
15 @Controller
16 @RequestMapping("/myWeb")
17 public class T00_UserController {
18 
19     @Autowired
20     private T00_UserService t00_userService;
21 
22     @RequestMapping("/name.json")
23     public @ResponseBody Map<String,String> showName(@RequestParam("id") Integer id){
24         T00_User t00_user = t00_userService.getT00_UserById(id);
25         Map<String,String> map = new HashMap<>();
26         map.put("name",t00_user.getName());
27         return map;
28     }
29 }
