SpringBoot用实体或Map接收Get请求传递过来的多个参数

@RestController
@RequestMapping("/test")
public class TestController {

    @GetMapping("/f1")
    public void func1(@RequestParam(required = false)Map map){
        System.out.println(map);
        //{name=新一, age=22}
    }

    @GetMapping("/f2")
    public void func2(Map map){
        System.out.println(map);
        //{}
    }

    @GetMapping("/f3")
    public void func3(User user){
        System.out.println(user);
        //{name=新一, age=22}
    }

    @GetMapping("/f4")
    public void func4(@RequestParam(required = false) User user){
        System.out.println(user);
        //{}
    }

    @GetMapping("/f5")
    public void func5(@RequestParam User user){
        System.out.println(user);
        //400 "message": "Required User parameter 'user' is not present",
    }

}

发送请求:http://localhost:8080/test/f1?name=新一&age=22

结论:
用Map接收需要加上@RequestParam(required = false)
用对应的实体类接收不能加其他注释,直接接收
