})
public class CorrespondenceDetailsForm {
    ...
}

重构

为了简化上述,我开始将这些列出的注释的几个逻辑组重构为单个自定义注释：(@FirstLifeContactDetailsObserver和@SecondLifeContactDetailsObserver).这是重构的类级别注释：

@FieldrequiredIf.List({
    @FieldrequiredIf(ifField="lifeAssuredIsPolicyOwner",groups = NonSingleNonMortgage.class)
})
@FirstLifeContactDetailsObserver
@SecondLifeContactDetailsObserver
public class CorrespondenceDetailsForm {
    ...
}

这并没有真正改善的情况,因为我需要一个验证器类为每个新的注释.

Spring MVC中是否有更好的跨域验证方法？
