未调用 handleMethodArgumentNotValid

Question

Im doing this project on spring boot 2.6.2. The error is that the handleMethodArgumentNotValid is not being called, because on Postman when I put the "nome" as null or exceding its max, instead of giving me the code 400 Bad Request, im receiving the 500 internal error

Hoping someone helps me out:)

Answer 1

Well from your posted stacktrace, it is throwing MysqlDataTruncation exception which is returned from MySQL, but handleMethodArgumentNotValid() is intended to handle MethodArgumentNotValidException , so it is very normal that it will not be called.

Also, if the exception is thrown because of the bean validation (ie @NotNull , @Size ), it will throw javax.validation.ConstraintViolationException and will not send request to MySQL like the current situation you show. Actually, you do not enable bean validation for your controller yet which requires you to annotate @Validated on it:

@Validated
@RestController
@RequestMapping("/categorias")
public class CategoriaResource {


}

So either create an exception handler to handle MysqlDataTruncation or enable bean validation for the controller and handle ConstraintViolationException
