JSR 303中的GroupSequence和有序评估 [英] GroupSequence and ordered evaluation in JSR 303

问题描述

在我们的应用程序中，有这样一种情况:

In our application we have such a case:

• 应按特定顺序评估约束. (价格便宜)
• 每个字段违反一次后，不应评估约束条件.
• 所有字段均应经过验证.

对于前两个，groupsequence非常合适.但是，对于我的第三个要求，我找不到解决方法.

For first two, groupsequence is fitting very good. However for my 3rd requirement I could not find a way to solve.

public class AccountBean {

   @CheepValidation
   @ExpensiveValidation
   @VeryExpensiveValidation
   private String name;

   @CheepValidation
   @ExpensiveValidation
   @VeryExpensiveValidation
   private String surname
}

例如，

比方说，对于名称字段VeryExpensiveValidationconstraint违反，对于姓氏字段ExpensiveValidation约束违反.

Let's say that, for name field VeryExpensiveValidationconstraint is violated and for surname field ExpensiveValidation constraint is violated.

在这种情况下，我应该显示:

For this case I should display:

对于字段名称:仅VeryExpensiveValidation错误消息 对于字段姓氏:仅ExpensiveValidation错误消息

For field name: Only VeryExpensiveValidation error message For field surname: Only ExpensiveValidation error message

请注意，对于字段姓氏，我们没有评估VeryExpensiveValidation约束.

Note that for field surname we did not evaluate VeryExpensiveValidation constraint.

是否可以使用JSR 303来实现它?

Is there a way to implement it with JSR 303?

谢谢

推荐答案

您可以使用组和@GroupSequence，但这有点笨拙.

You can use groups and @GroupSequence, but it's a bit unwieldy.

public class AccountBean {

   @CheapValidation(groups=Name1.class)
   @ExpensiveValidation(groups=Name2.class)
   @VeryExpensiveValidation(groups=Name3.class)
   String name;

   @CheapValidation(groups=Surname1.class)
   @ExpensiveValidation(groups=Surname2.class)
   @VeryExpensiveValidation(groups=Surname3.class)
   String surname;

   public interface Name1 {}
   public interface Name2 {}
   public interface Name3 {}
   @GroupSequence({Name1.class, Name2.class, Name3.class})
   public interface Name {}

   public interface Surname1 {}
   public interface Surname2 {}
   public interface Surname3 {}
   @GroupSequence({Surname1.class, Surname2.class, Surname3.class})
   public interface Surname {}
}

然后使用以下方法进行验证:

Then validate with:

validator.validate(myAccountBean,
    AccountBean.Name.class, AccountBean.Surname.class)

关键是要有两个完全独立的组序列.

The key is to have two entirely independent group sequences.

不幸的是，看来您必须明确列出要验证的所有字段的组.我无法使其与默认" @GroupSequence一起使用.任何人都可以对此进行改进吗?

Unfortunately, it seems you must explicitly list the groups for all the fields you want to validate. I wasn't able to get it working with a 'default' @GroupSequence. Can anyone improve on this?
