线程“Thread-10”中的异常java.lang.IllegalStateException
问题描述：
我不太清楚如何解释这个问题，而不是我想要用数据填充的四个表中的每一个，有时其中一些是只是空着。我无法预测哪些是空的。它可能是1和2，或者只有3，或者只有一个表。当其中一个表没有被填充时，我会在rollback（）catch块中结束。有时他们都工作。这与某种线程中断有关。鉴于下面的代码和例外情况，会出现什么问题？线程“Thread-10”中的异常java.lang.IllegalStateException

答
我觉得你的问题在这里：
} catch (Exception e) {
entityManager.getTransaction().rollback();
}
问题＃1 - 你是压垮例外。您不会打印该消息，也不会记录堆栈跟踪。没有。您只需扔掉所有可用于诊断问题的信息。
问题＃2 - 您正在捕捉Exception。这太宽泛了。
问题＃3 - 看起来，当你到达呼叫rollback时，没有事务回滚。
我认为如果您解决问题＃1和＃2，问题＃3的原因将被揭示。
没错。感谢您指出了这一点。我已经添加了堆栈跟踪并更新了我的问题。望着它... – santafebound
是的。它解释了你的问题的根源。尝试搜索有关* that *异常消息的问答。 –
