尝试将表单数据注入数据库时出现javax.ejb.EJBException

我正试图根据表单输入将数据注入数据库，但当我提交表单时，我遇到了一个严重的异常，我似乎无法围绕一个可扩展的解决方案进行思考，我已经尝试了很多。。。也许你能帮忙？我不确定这个节目想告诉我什么

如果它对您有用，请参见下面我的代码中它所指的行：

在controller.ControllerServlet.doPost（ControllerServlet.java:409）中，引用代码：

int orderId = orderManager.placeOrder(FN, LN, EM, PN, A1, CTRY, SPR, PZC, CT, cart);

em.persist(customer);

Customer customer = addCustomer(FN, LN, EM, PN, A1, CTRY, SPR, PZC, CT);

在session.OrderManager.addCustomer（OrderManager.java:55）中，引用代码：

int orderId = orderManager.placeOrder(FN, LN, EM, PN, A1, CTRY, SPR, PZC, CT, cart);

em.persist(customer);

Customer customer = addCustomer(FN, LN, EM, PN, A1, CTRY, SPR, PZC, CT);

在session.OrderManager.placeOrder（OrderManager.java:34）中，引用代码：

int orderId = orderManager.placeOrder(FN, LN, EM, PN, A1, CTRY, SPR, PZC, CT, cart);

em.persist(customer);

Customer customer = addCustomer(FN, LN, EM, PN, A1, CTRY, SPR, PZC, CT);

您的模型上有一个违反的约束，该约束在持久化到数据存储之前被检测到。这意味着您的客户或相关实体的验证（例如@NotNull、@Size）不受尊重。我认为原因（堆栈跟踪中较低的级别）可能会为您提供有关此违规行为的更多信息。

谢谢兄弟！这就是它原来的样子！我从试图注入数据库的每个类中删除了每个@NotNull注释，它成功了！：D
