连接与托管connection.org.jboss.resource.adapter.jdbc.jdk6.WrappedConnectionJDK6无关

Question

我在JBoss服务器上使用Hibernate.我收到以下错误.

当我尝试在同一个sesssion中第二次连接到数据库时发生错误.

此外,我收到错误"为您关闭连接.请关闭您的连接".

可能是什么原因,我该如何解决这种情况？

Answer 1

自从你一年前提出这个问题以来,这个答案实际上已经太晚了.但它将帮助那些将来会遇到这个错误的人.

您的错误可能来自不同的来源,但在我的情况下,它的全部是关于事务超时,一些查询可能需要很长时间才能达到超时,并且hibernate会抛出异常.在我的情况下,我所做的是将事务超时设置为更高的值.这解决了我的问题.
