我使用Spring和Spring MVC 3.1,Hibernate 3,Hibernate Validator 4.3.

我想添加我的自定义约束验证器,但似乎我的验证器没有被调用,并且总是得到"找不到类型的验证器"异常.我犯了什么错吗？总是遇到这个例外我遇到了很大的问题

javax.validation.UnexpectedTypeException: HV000030: No validator could be found for type: java.lang.String.

    at org.hibernate.validator.internal.engine.ConstraintTree.findMatchingValidatorClass(ConstraintTree.java:375)

但是,如果我删除我的自定义约束验证器,一切正常.这是我的代码,你能帮忙找到导致这个异常的来源吗？

test.constraint.ActorConstraint

@Target({ElementType.METHOD, ElementType.FIELD, ElementType.ANNOTATION_TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Constraint(validatedBy=ActorConstraintValidator.class)
public @interface ActorConstraint {

  String message() default "Actor already exists in database";
  public abstract Class<?>[] groups() default {};
  public abstract Class<? extends Payload>[] payload() default {};

}



test.constraint.ActorConstraintValidator
@Component
public class ActorConstraintValidator implements ConstraintValidator<ActorConstraint, Actor> {

  @Autowired
  private ActorModel actorModel;

  @Override
  public void initialize(ActorConstraint arg0) {
    System.out.println("ActorConstraintValidator is initialized");
  }

  @Override …
