我有一个Jboss,Seam,Hibernate和h2的应用程序.我写了一个简单的操作,用于从外部文件将数据导入数据库.
@Name("importAction") @AutoCreate @Scope(ScopeType.CONVERSATION) @Transactional public class ImportCosAction extends AbstractAction { saveOrUpdate(member); protected void saveOrUpdate(AbstractEntity entity) { final Session session = getSession(); session.saveOrUpdate(entity); flushSession(); }
它按预期的数量工作,但是,在某些时候我得到以下异常:
16:50:13,558 ERROR [JDBCExceptionReporter] Connection is not associated with a managed connection.org.jboss.resource.adapter.jdbc.jdk5.WrappedConnectionJDK5@3c4b0529 16:50:13,558 ERROR

解决方法
此错误意味着您的代码正在使用不再有效的连接(即由于连接错误导致的关闭/销毁连接或由上游其他代码段关闭缓存连接的应用程序的无效连接缓存).在您的情况下,池中的连接ID是@ 3c4b0529.因此,您可以在TRACE级别日志记录中参考此信息,以查看是否可以找出连接关闭的原因(由于某些错误,例如DB终止连接或网络问题或应用程序代码错误地处理连接).
>您应优化代码,以使事务完成时间不长.另一个选项是在TransactionManager bean的deploy / transaction-jboss-beans.xml中增加事务超时: –
….
300
….
默认值为5分钟(300秒).增加此事务超时可能会有所帮助,但这实际上并不能解决根本原因,即您在应用程序中运行的长时间事务.增加事务处理时间的一个副作用是保持资源更长时间,从而对JBoss中其他服务的性能产生负面影响.
我希望你不打算在生产中使用h2. h2不适用于持久性的生产用途.
>您还应检查数据源设置,以确保未禁用idle-timeout-minutes(设置为0).默认值为15分钟,如果您的连接在事务之间空闲的时间超过该时间段,则可以增加它.>最后,确保您没有缓存任何数据源连接对象或语句,这些对象或语句可能会持久存在过时的连接或语句.
