问题描述

当我部署我的应用程序时，它完美运行，直到我进行更改，保存，并且netbeans热部署应用程序。此时，我在具有@entity并且包含在我的persistence.xml中的类中获得了一个未知的实体bean类错误。发生这种情况时，任何与jpa有关的事都会停止工作。只有当我重新启动服务器时，我的jpa内容才会重新开始工作。

When I deploy my app, it works perfectly until I make a change, save, and netbeans hot deploys the application. At this point I get an unknown entity bean class error on a class that has the @entity and it's included in my persistence.xml. When this happens, anything dealing with jpa stops working. Only if I restart the server will my jpa stuff start working again.

如果我在项目中将save部署为save，我只手动保存和部署我得到的相同结果。

If I turn deploy on save off in my project and I only manually save and deploy I get the same results.

这只是一个netbeans / glassfish错误吗？或者我的jpa设置有问题吗？

Is this just a netbeans/glassfish error? Or is there something wrong with my jpa setup?

例外

java.lang.IllegalArgumentException: Unknown entity bean class: class amc.nase.idms.persistence.model.SecSession, please verify that this class has been marked with the @Entity annotation.

推荐答案

问题是旧的持久性单元，引用了重新部署后，旧类仍然存在。确保旧的EntityManagerFactory已关闭。 Glassfish应该为任何托管工厂（如SessionBean）处理此问题，但如果您管理自己的工厂，则需要确保这些工厂已关闭。

The issue is the old persistence unit with references to the old classes is remaining after your redeploy. Ensure the old EntityManagerFactory is getting closed. Glassfish should handle this for any managed factories such as in a SessionBean, but if you are managing your own factories you need to ensure these are closed.
