很难确定你发布的代码,但我怀疑 ResultSet
是无意中关闭(或 stm
正在重复使用) 正文内部
循环 。这将在下一次迭代开始时触发异常。
It's hard to be sure just from the code you've posted, but I suspect that the ResultSet
is inadvertently getting closed (or stm
is getting reused) inside the body of the while
loop. This would trigger the exception at the start of the following iteration.
此外,您需要确保应用程序中没有其他线程可能使用相同的线程数据库连接或 stm
对象。
Additionally, you need to make sure there are no other threads in your application that could potentially be using the same DB connection or stm
object.
