我有一个Spring Boot应用程序,hibernate异常每天晚上的特定时间都会出现。例外情况是: could not execute statement; SQL [n/a]; nested exception is org.hibernate.PessimisticLockException: could not execute statement 以下是堆栈跟踪: Caused by: org.hibernate.PessimisticLockException: could not execute statement
at org.hibernate.dialect.My
在使用JDBC与数据库运行的函数上,我得到了一个奇怪的SQLException。SQLException:找不到列'Message‘。
我的职责是:
st = con.prepareStatement("SELECT NotificationID,UserIDFrom,UserIDTo,Message,Timestamp,isNotified FROM notification WHERE UserIDTo=? AND isNotified=?");
st.setInt(1, _UserID);
st.setBoolean(2, false);
这是在保存增量导入状态时得到的。

我们收到以下错误。

一些用户通过android错误报告弹出窗口报告了这个错误,但我不知道是什么原因造成的。我用谷歌搜索了一下,但我找不到任何好的线索。
有人知道是什么导致了这个错误吗?
