springboot中get post put delete 请求

组合注解(RequestMapping的变形)

• @GetMapping = @RequestMapping(method = RequestMethod.GET)
• @PostMapping = @RequestMapping(method = RequestMethod.POST)
• @PutMapping = @RequestMapping(method = RequestMethod.PUT)
• @DeleteMapping = @RequestMapping(method = RequestMethod.DELETE

1、原始springMVC的请求

package com.example.springdemo.hello;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class OrginController {
    /**
     * 原始的写法
     * @return
     */
    @RequestMapping(value = "/orginController",method = RequestMethod.GET)
    @ResponseBody
    public String orginController(){
        return "orginController";
    }
}

如图：

2、使用SpringBoot的请求

package com.example.springdemo.hello;

import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.Map;

@RestController
public class RequestDemoController {

    /**
     * RestController相当于Controller+repsoneBody
     */
    /**
     * 通过@PathVariable接收参数
     */
    @GetMapping(value="/test1/{id}/{name}")
    public Map<String, Object> getMap(@PathVariable("id") String id,@PathVariable("name") String name) {
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",id);
        map.put("name",name);
        return map;
    }

    /**
     * get请求的用法
     * @param id
     * @param name
     * @return
     */
    @RequestMapping(value = "/gettest1",method = RequestMethod.GET)
    public Map<String,Object> getController(@RequestParam(value="id") String id,@RequestParam(value="name") String name){
        Map<String,Object> map = new HashMap<String, Object>();
      map.put("id",id);
      map.put("name",name);
      return map;
    }
    @GetMapping(value="gettest2")
    public Map<String, Object> getController2(@RequestParam(value="id") String id,@RequestParam(value="name") String name) {
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",id);
        map.put("name",name);
        return map;
    }

    /**
     * post请求的用法
     */
    @RequestMapping(value = "/posttest1",method = RequestMethod.POST)
    public Map<String,Object> postController(@RequestBody User user){
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",user.getId());
        map.put("name",user.getName());
        return map;
    }
    @PostMapping(value="posttest2")
    public Map<String, Object> postController2(@RequestBody User user) {
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",user.getId());
        map.put("name",user.getName());
        return map;
    }

    /**
     * put请求的用法
     */
    @RequestMapping(value = "/puttest1",method = RequestMethod.PUT)
    public Map<String,Object> putController(@RequestBody User user){
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",user.getId());
        map.put("name",user.getName());
        return map;
    }
    @PutMapping(value="puttest2")
    public Map<String, Object> putController2(@RequestBody User user) {
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",user.getId());
        map.put("name",user.getName());
        return map;
    }

    /**
     * delete请求的用法
     */
    @RequestMapping(value = "/deletetest1",method = RequestMethod.DELETE)
    public Map<String,Object> deleteController(@RequestParam(value="id") String id){
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",id);
        return map;
    }
    @DeleteMapping(value="deletetest2")
    public Map<String, Object> deleteController2(@RequestParam(value="id") String id) {
        Map<String,Object> map = new HashMap<String, Object>();
        map.put("id",id);
        return map;
    }
}

通过POSTMAN测试接口的截图

1）path

2）get请求

3）post请求

4）put请求

5）delete请求
