当我运行我的应用程序时，抛出如下异常：
严重：加载应用程序时出现异常 严重：上下文/wren6-fp 取消部署失败 严重: Exception while loading the app : jakarta.ejb.CreateException: Initialization failed for Singleton DBIinitService jakarta.ejb.CreateException：单例 DBInitService 初始化失败
Caused by: jakarta.ejb.EJBTransactionRolledbackException: Exception thrown from bean: jakarta.validation.ConstraintViolationException: One or more Bean Validation constraints were violated while executing Automatic Bean Validation on callback event: prePersist for class: edu.iit.sat.itmd4515.wren6.domain.Order. Please refer to the embedded constraint violations for details.

但是谁能告诉我如何找到具体的违规行为？ 这是我的订单实体代码：

我测试了订单实体。如果只创建一行，没有错，只有超过 2 行才会产生这个错误。
我只是定位我的订单实体来查找我的错误。修改validaiton约束后，一切正常。 谢谢你们！！
