java - @Size hibernate注解可以继承吗？

Question

我正在尝试使用 hibernate 验证来检查列表的大小。一般来说，我希望列表为空，除非它是 B 类型的对象。似乎不起作用:

public static class A
{
    private List<Integer> inheritedRemoveAnnotation = new ArrayList<Integer>();

    @Size(max=0)
    public List<Integer> getInheritedRemoveAnnotation()
    {
        return inheritedRemoveAnnotation;
    }
}
public static class B extends A
{
    @Override
    @Size(max=Integer.MAX_VALUE)
    public List<Integer> getInheritedRemoveAnnotation()
    {
        return super.getInheritedRemoveAnnotation();
    }
}

private static Validator m_validator = Validation.buildDefaultValidatorFactory().getValidator();
public static void main(String[] args)
{
    B b = new B();
    b.getInheritedRemoveAnnotation().add(1);
    System.out.println(m_validator.validate(b));
}

我得到的输出是:
[ConstraintViolationImpl{interpolatedMessage='大小必须介于 0 和 0 之间', propertyPath=inheritedRemoveAnnotation, rootBeanClass=class oshai.hibernatevalidators.TestInheritence$B, messageTemplate='{javax.validation.constraints.Size.message}'}]

还会检查层次结构中某个位置的所有约束。根据documentation :

Constraint annotations are aggregated if methods are overridden.
