Answer 1

这是因为某些数据库连接未显式关闭。这可能是由于Hibernate事务配置不当造成的。

由于你在JBoss上运行，你必须确保Hibernate使用“JTA”并且Hibernate可以找到你的XA数据源：

hibernate.connection.datasource=java:/comp/env/jdbc/datasource
hibernate.transaction.factory_class=org.hibernate.transaction.JTATransactionFactory
hibernate.transaction.manager_lookup_class =org.hibernate.transaction.JBossTransactionManagerLookup

如果问题仍然存在，请检查the following SO question。

虽然CMT，“为你关闭一个连接。请自己关闭它们：”
