Hibernate Validator Custom Constraint 依赖于基类答案

【问题描述】：

我可以使用 Hibernate Validator (w/i Spring boot) 创建一个自定义约束，其中验证取决于子类吗？示例：

public class Engine {
   @NotEmpty
   private String name;
   @NotNull
   private int power;
   @NotNull // HERE I ONLY NEED VALIDATE IF THIS CLASS ARE ONE PROP FROM Car Class
   private int color;

   ... getter and setter
}

Here I have 2 classes,

public class Car {
   @NotEmpty
   private String name;
   @Valid
   private Engine engine;
   ... getter and setter
}

public class Bike {
   @NotEmpty
   private String name;
   @Valid
   private Engine engine; // HERE I DONT NEED TO VALIDATE THE COLOR
   ... getter and setter
}

【解决方案1】：

你应该可以使用@ConvertGroup做你想做的事：

组接口：

public interface BasicEngineChecks {
}

public interface ExtendedEngineChecks {
}

更新示例：

@GroupSequence({ BasicEngineChecks.class, ExtendedEngineChecks.class })
public class Engine {
   @NotEmpty(groups = BasicEngineChecks.class)
   private String name;

   @NotNull(groups = BasicEngineChecks.class)
   private int power;

   @NotNull(groups = ExtendedEngineChecks.class)
   private int color;

   // ...
}

汽车没有什么特别之处。级联验证将通过默认组，该组被转换为 BasicEngineChecks 和 ExtendedEngineChecks 的所有约束

public class Car {
   @NotEmpty
   private String name;

   @Valid
   private Engine engine;

   // ...
}

对于Bike，我们进行显式转换，仅评估BasicEngineChecks：

public class Bike {
   @NotEmpty
   private String name;

   @Valid
   @ConvertGroup(from = Default.class, to = BasicEngineChecks.class)
   private Engine engine; 

   // ...
}
