Bean Validation transforms Object RequestParam into @RequestBody

I have the following: 

 @PostMapping(produces = MediaType.APPLICATION_JSON_VALUE)
 public ResponseEntity<LoginResponse> getLoginStatus(@Valid LoginRequest loginRequest){
        //some stuff here
 }

The loginRequest paramater is a @RequestParam, but, because it is a custom object, the @RequestParam annotation in front of the object is not needed. The problem is that when any bean-validation annotation is put in front of the custom object, the object is transformed into a body parameter(@RequestBody), but we want to validate the object as request param, not body param.

Could anyone help me, please?

Solution

  • The reason why the LoginRequest attributes became part of the RequestBody, and not of RequestParameters anymore, is due to springfox-swagger version 2.6.1. Upgrading to version 2.7.0 fixed this issue for us.
