Java Beanの検証、hibernate-validator 4.xおよびConstraintValidatorの問題

Question

hibernate-validator 4.xでBeanの検証に問題があります。カスタムバリデータInterdateはまったく呼び出されません。

マイオーバーsimplificatedコードが欠けている何休止ドキュメントhttp://docs.jboss.org/hibernate/validator/4.2/reference/en-US/html/validator-customconstraints.html

のようなものですか？

    } 

    @Override

     return false; 
    }

public class Book { 
    @InterdateI 
    private String a; 
} 

public void i() { 
    Validator validator = Validation.buildDefaultValidatorFactory().getValidator(); 

    Book book = new Book(); 

    Set<ConstraintViolation<Book>> constraintViolations = validator.validate(book); 
    System.out.println(constraintViolations.size()); 
} 

     public static void main(String[] args) { 
    new M().i(); 
} 
    }

私はあなたがあなたの制約注釈にこれらの注釈を追加shuoldとします

@Target({ METHOD, FIELD, ANNOTATION_TYPE }) 
@Retention(RUNTIME) 
@Constraint(validatedBy = Interdate.class) 
@Documented 
public @interface InterdateI { 
    String message() default "Boum"; 

    String[] groups() default {}; 
} 

それ以外の場合はut @ Retention（RUNTIME）annotion @InterdateI on Book.aフィールドは実行時に保持されません。
