尝试将数据输入DB时出现InvalidStateException [英] InvalidStateException while trying to enter data into DB

问题描述

我有一个方法返回特定DB的实体管理器。当我第一次使用该方法获取实体管理器时，一切正常。我可以使用实体管理器将数据保存到任何表A，B，C中。现在说我在表B中保存时出现异常

I have a method that return the entity manager for particular DB.Now when i use the method for the first time to get entity manager everything works fine.I can save data into any tables A,B,C using entity manager.Now say i get a exception while saving in table B

现在当我尝试在上面发生异常后对DB执行任何操作时，下次我尝试运行相同的代码在表A本身更新时失败。我可以看到下面的结果

Now when I try to perform any operation on DB after geting exception above, the next time i try to run same code it fails when updating in table A itself.I can see folloing eception

推荐答案

在您的代码中的某个地方，您（或框架）关闭您的的EntityManagerFactory 。确保你没有在它上面调用 close（）。

Somewhere in your code you (or a framework) close your EntityManagerFactory. Make sure you didn't call close() on it.
