Connection is not associated with a managed connection.org.jboss.resource.adapter.jdbc.jdk5.WrappedConnectionJDK5@17240d9

jboss自动关闭数据连接，有时会出再如上异常，连接未关闭，解决办法

1，手动关闭每一个连接

2.首先把 D:/jboss/server/default/deploy/jboss-web.deployer/server.xml 里的

                  cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager"
                transactionManagerObjectName="jboss:service=TransactionManager" />

  注释去掉

然后

   If you are using Hibernate, it is recommended to add a "hibernate.connection.release_mode" property on value "auto" (the default) in your hibernate.cfg.xml file.

This did not work for me. So I found the following workaround:
To remove the message you need to set the "Debug" property to "false" in the CachedConnectionManager mbean configuration, in the jbossjca-service.xml file, for example:
 

    jboss:service=TransactionManager
    false
