我对Spring Data JPA Repository接口方法有一个非常奇怪的问题。
方法很简单：
List<Records> findByClientNameIgnoreCaseContainingAndRecordDateBetween (String client, Date startDate, Date endDate) throws DataAccessException;
这在测试数据库上运行得很好，但是在生产数据库上，应用程序开始执行此查询，然后在17分钟后它会抛出此异常：
ERROR SqlExceptionHelper - Closed Connection: next
这是完整的堆栈跟踪：

一个非常有趣的事情是我有一个removeAbandonedTimeout设置为30秒，并且应用程序仍在工作17分钟，试图执行查询。
答案 0 :(得分：0)
从存储库查询方法中删除IgnoreCaseContaining解决了该问题。
