我有这门课

@HasNose
@HasMouth
public class Person {

    String fieldA;
    String fieldB;
    // getters and setters

}

现在自定义注释验证器看起来像这样

// validator of @HasNose
@Override
public boolean isValid(Object object, 
                        ConstraintValidatorContext context) {

    // some tests that determine there is an error
    context.disableDefaultConstraintViolation();
            context.buildConstraintViolationWithTemplate("Some message")
            .addNode("fieldA")
            .addConstraintViolation();

}

和

// validator of @HasMouth
@Override
public boolean isValid(Object object, 
                        ConstraintValidatorContext context) {

    // some tests that determine there is an error
    context.disableDefaultConstraintViolation();
            context.buildConstraintViolationWithTemplate("Some message")
            .addNode("fieldB")
            .addConstraintViolation();

}

运行它会产生异常：

出于某种原因，“ConstraintValidatorContext”正在连接两个字段。调试显示属性“propertyPath”已经用“fieldA”填写。我认为它应该在每个约束验证器的根级别，不是吗？

我找到了解决我自己问题的方法，我使用的是 hibernate-validator-4.2.0.BETA2。切换到 hibernate-validator-4.2.0.FINAL 解决了这个问题。

经验教训：保持你的库更新......
