Validateur personnalisé message: le fait de Lancer une exception dans la mise en œuvre de ConstraintValidator cause UnexpectedException

J'ai donc validateur personnalisé et quand je return de la valeur à false puis il travaille -

import com.vhealth.api.service.UserService;
import com.vhealth.api.utils.exceptions.InvalidPayloadException;
import org.springframework.beans.factory.annotation.Autowired;

import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;


public class UserNameUniqueValidator implements ConstraintValidator<UserNameUnique, String> {
    @Autowired
    UserService userService;

    @Override
    public void initialize(UserNameUnique constraintAnnotation) {
    }

    @Override
    public boolean isValid(String userName, ConstraintValidatorContext context) {
        if (userService.findByUserName(userName) != null) {
            throw new InvalidPayloadException("Creating user requires unique userName new");
            //return false;
        }
        return true;
    }
}

Mais quand j'essaie de lancer une exception dans cette section, j'obtiens le message d'erreur que le problème est causé par mon exception personnalisée:

Exception est placé dans @Controller ExceptionResolover

    @ExceptionHandler(InvalidPayloadException.class)
public ResponseEntity handleEmptyFieldException(InvalidPayloadException ex) {
return new ResponseEntity(ex.getMessage(), HttpStatus.BAD_REQUEST);
}

Edit: Lancer de InvalidPayloadException exception dans UserNameUniqueValidator retourne message personnalisé donc j'évite d'utiliser BindingResult dans le contrôleur principal pour l'extraction de message par défaut de validaor

hibernate est d'emballage de l'exception, vous pouvez voir l'-vous de jeter à bas de la pile.

Si vous souhaitez afficher un message personnalisé essayer ce morceau de code.
```
@Override
public boolean isValid(String userName, ConstraintValidatorContext context) {
if (userService.findByUserName(userName) != null) {
context.disableDefaultConstraintViolation();
context
.buildConstraintViolationWithTemplate("User " + userName + "already exists!")
.addConstraintViolation();
return false;
}
return true;
}
```
- Qui a travaillé instantanément, je suis toujours curieux de connaître ce problème en se jetant d'exception personnalisée à partir du programme de validation cependant, après l'application de votre solution, je ne vois pas l'intérêt en recourant à l'exception ici 🙂

Êtes-vous d'obtenir l'erreur du compilateur.
Veuillez vérifier l'erreur renvoyée est

Caused by: com.vhealth.api.utils.exceptions.InvalidPayloadException: Creating user requires unique userName new

Je pense que cela ne signifie que l'exception que vous avez jeté est une exception Imbriquée

Également de vérifier la stacktrace
au com.vhealth.api.controller.ApiUserControllerTest.shouldReturnErrorMessageToAdminWhencreatinguserwithusedusername(ApiUserControllerTest.java:53)

Vous pouvez ajouter not null check! Vous pouvez toujours suivre [mchrobok] réponse
Je pense que mieux sera:

@Override
public boolean isValid(String userName, ConstraintValidatorContext context) {
if (userService !=null && userService.findByUserName(userName) != null) {
context.disableDefaultConstraintViolation();
context
.buildConstraintViolationWithTemplate("User " + userName + "already exists!")
.addConstraintViolation();
return false;
}
return true;
}
