The postman test interface has 404 or 500 errors when the URL is configured correctly

1. use postman In the process of debugging the interface , appear 404, The annotation on the first confirmation category is @RestController

  Otherwise, it will appear during the test 500

2. Determine whether there is a declaration on the method PostMapping perhaps GetMapping

3.uri Path confirmation is OK

@RestController
@RequestMapping("/test")
public class TestController {
    @GetMapping  // Get rid of GetMapping Will appear 404
    public Result test(){
        SysUser sysUser= UserThreadLocal.get();
        System.out.println(sysUser);
        return Result.success(null);
    }


}

add @GetMapping Test success

  summary ：404 Resource not found , Nothing more than interface path , submission 、 Parameter type 、 There is a problem with the return result type .
And the result returned by our interface should json Formatted data , So add the @ResponseBody Or use @RestController that will do .
