请不要将其作为重复项关闭。关于此问题有很多链接，但这是不同的。我不能将代码放在这里。我可以解释这种情况
我的代码的一部分确实使用java中的jpa / hibernate保存和删除。我在AWS环境中使用服务器A1中的应用程序和D1中的sqlserver数据库运行此应用程序。我每次单击特定按钮时都会看到它执行一些dml操作，但是方法结束后，它将引发上述异常。但我看到这些行已修改，仍然可以看到错误
要进行检查，我安装了本地应用程序（A2）和数据库（D2）服务器，并且工作正常。我将本地应用程序（A2）连接到D1服务器。令人惊讶的是，我仍然没有看到任何问题。
仍然想知道应用程序服务器如何对此错误负责。如果有人遇到这个奇怪的问题，请提供帮助。这是堆栈跟踪
谢谢！
