Spring Data REST如何返回hibernate-JPA验证&json中的服务器内部错误而不是堆栈跟踪

Question

我希望获得json格式的JPA验证和服务器内部错误,而不是堆栈跟踪,

使用Spring JPA data REST

@RepositoryRestResource(path = "entity")
public interface MyEntityRepo extends CrudRepository<MyEntity, Long> {}

当post没有name，address属性时，我希望验证错误不为NULL。

curl -i -X POST -H "Content-Type: application/json" -d '{"name":"not passed and @NotNull","address":"not passed and @NotNull","city":"city","area":"area"}' http://localhost:8080/clinicfinder/api/entity

当前回报：

所需返回：

response 404, {"errors":[{"entity":"MyEntity","message":"may not be null","invalidValue":"null","property":"name"},{"entity":"MyEntity","message":"may not be null","invalidValue":"null","property":"address"}]}
