JSR 303 - Name of the annotated field in the custom validator

Question

I have a question about custom annotations. More precisely, do I have access to the name of the annotated field inside the custom validator ? If yes, how do I access this?

Thanks

Answer 1

No, you can't access the name of the validated element from within a constraint validator. It is exposed by the resulting constraint violation, though (via getPropertyPath() ).

Answer 2

在休眠实现中，可以使用反射ConstraintValidatorContext.basePath.currentLeafNode.name来获取它。

Answer 3

您可以通过以下exp访问路径

((ConstraintValidatorContextImpl) context).getConstraintViolationCreationContexts().get(0).getPath()
