Spring REST validation

I have this REST API method

 @GetMapping
 public ResponseEntity doSome(@Valid DataTypeRequest dataType){}

and ConstraintValidator that validates DataTypeRequest.

Now I should implement HandlerMethodArgumentResolver for DataTypeRequest, so my REST API method will look like:

@GetMapping public ResponseEntity doSome(@Valid @DataTypeRequestAnnotation DataTypeRequest dataType){}

And after this changes HandlerMethodArgumentResolver works but ConstraintValidator doesn't. So how can I validate my entity after HandlerMethodArgumentResolver.

You can check parameter for @Valid and invoke validate() method.

if (parameter.hasParameterAnnotation(Valid.class){            
    binderFactory
        .createBinder(webRequest, resolvedObject, "resolvedObjectLogicalName")
        .validate ();
}
