尝试将数据输入数据库时出现 InvalidStateException
我有一个方法可以返回特定数据库的实体管理器。现在，当我第一次使用该方法来获取实体管理器时，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
现在，当我在获得上述异常后尝试对数据库执行任何操作时，下次我尝试运行相同的代码时，在表 A 本身中更新时会失败。我可以看到以下接收结果

在代码中的某个位置，您（或框架）关闭您的
EntityManagerFactory。确保您没有对其调用close()。Somewhere in your code you (or a framework) close your
EntityManagerFactory. Make sure you didn't callclose()on it.
