Question

Это не та же проблема, что это . Следуя приведенному здесь ответу, если я добавлю spring.jpa.properties.javax.persistence.validation.mode=none, мой собственный валидатор даже не будет вызван.

Вариант использования

Моя таблица имеет 3 столбца - id , role и user_id . Теперь может быть только 1 строка, для которой роль может принимать значение ROLE_ ROOT. И как только эта запись вставлена, она не может быть обновлена.

Как я пытаюсь реализовать

Используя пользовательский javax .validation.ConstraintValidator и проверка наличия записи для role = ROLE_ ROOT внутри isValid

(я знаю, что есть альтернативы для этого. например, перед вызовом repository.save(..) , позвоните repository.findByRole(..), проверьте и ограничьте. Но я хочу понять, почему этот сценарий не работает.)

Какую ошибку я получаю

java.lang.StackOverflowError: null и строка ~~~~~~validation check печатается сотни раз.

Мой код

MyController class

@RestController
public class MyController {

  @Autowired
  private MyTableRepository repository;

  @GetMapping("/hello")
  public void hello() {
    MyEntity myEntity = new MyEntity();
    myEntity.setId(123456);
    myEntity.setRole("ROLE_ROOT");
    myEntity.setUserId(3);

    repository.save(myEntity);
  }
}

MyRepository class

@Repository
public interface MyTableRepository extends JpaRepository<MyEntity, Integer> {

  List<MyEntity> findByRole(String roleName);
}

MyEntity class

@Entity
@Table(name = "my_table")
public class MyEntity {

  @Id
  @Column(name = "id")
  private int id;

  @Column(name = "role")
  @CheckRole
  private String role;

  @Column(name = "user_id")
  private int userId;

  public int getId() {
    return id;
  }

  public void setId(int id) {
    this.id = id;
  }

  public String getRole() {
    return role;
  }

  public void setRole(String role) {
    this.role = role;
  }

  public int getUserId() {
    return userId;
  }

  public void setUserId(int userId) {
    this.userId = userId;
  }

}

My Custom Annotation

@Target({ FIELD, ANNOTATION_TYPE, METHOD, PARAMETER })
@Retention(RUNTIME)
@Constraint(validatedBy = RoleValidator.class)
public @interface CheckRole {

  String message() default "{org.hibernate.validator.referenceguide.chapter06.CheckCase.message}";
  Class<?>[] groups() default { };
  Class<? extends Payload>[] payload() default { };
}

Мой пользовательский класс валидатора

public class RoleValidator implements ConstraintValidator<CheckRole, String> {

  private final MyTableRepository repository;

  public RoleValidator(MyTableRepository repository) {
    this.repository = repository;
  }

  @Override
  public void initialize(CheckRole constraintAnnotation) {

  }

  @Override
  public boolean isValid(String value, ConstraintValidatorContext context) {
    if(value.equals("ROLE_ROOT")){
      System.out.println("~~~~~~validation check");
      return (repository.findByRole("ROLE_ROOT").size() > 0);
    }
    else {
      return true;
    }
  }

}

Мой ValidatorAddingCustomizer (после этого вопрос )

@Component
public class ValidatorAddingCustomizer implements HibernatePropertiesCustomizer {

  private final ObjectProvider<Validator> provider;

  public ValidatorAddingCustomizer(ObjectProvider<javax.validation.Validator> provider) {
    this.provider = provider;
  }

  public void customize(Map<String, Object> hibernateProperties) {
    Validator validator = provider.getIfUnique();

    if (validator != null) {
      hibernateProperties.put("javax.persistence.validation.factory", validator);
    }
  }
}

валидатор гибернации версия: 5.2.4. Окончательная версия загрузки Spring: 2.3.1.RELEASE

Вот ссылка friendpaste , содержащая весь код.

Последующий вопрос по этому поводу:

Если я помечу столбец id MyEntity как @GeneratedValue(strategy = GenerationType.IDENTITY) с сохранением остальной части кода, то ошибка изменится на следующую

AutoFlush on before query execution и Another query execution attempt on AutoFlush рекурсия

Вы пытаетесь сохранить свою сущность, и preInsert срабатывает проверка.
При проверке вы выполняют запрос к одному и тому же объекту, что означает, что перед выполнением запроса в спящем режиме необходимо проверить sh то, что поставлено в очередь в вашем сеансе.
Попытка заразить sh снова вызывает проверку preInsert, и это повторяется.

Один из способов остановить Auto flu sh по запросу

К сожалению, вам нужно добавить такой метод в свой репозиторий в остановить autoFlush(), происходящее для этого запроса.

    @Query("Select count(m) from MyEntity m where m.role = :roleName")
    @Transactional(propagation = Propagation.NOT_SUPPORTED)
    Long count(String roleName);

Когда запрос выполняется без транзакций, спящий режим не должен проверять sh перед запросом, поэтому он не будет go в рекурсию.
