Hibernate java.lang.IllegalStateException:EntityManager已关闭

我正在构建一个JAR文件，部署到JBoss 4.2.3.GA（情不自禁），使用Hibernate 4.1.5.SP1和validator 4.3.0.Final。数据库是MySQL 5.5。我在使用RESOURCE_LOCAL EntityManager执行基本选择时遇到问题。我有

        for (final Order order : results) { 
        ...                 
                    try { 
                        session = (Session)em.getDelegate();
                        state = findStateByAbbrev(stateAbbrev, session);
                    } catch (HibernateException e) {
                        e.printStackTrace(System.err);
                        LOG.error(e.getMessage(), e);
                    } finally {
                        em.close();
                    }   // try 

        }   // for

private State findStateByAbbrev(final String abbrev, final Session session) {
    State ret = null;
    final Criteria crit = session.createCriteria(State.class).add(Restrictions.eq("abbrev", abbrev));
    final List<State> results = crit.list();
    if (results != null && results.size() > 0) {
        ret = results.get(0);
    }   // if
    return ret;
}

谢谢-戴夫

编辑：在我的代码运行时间超过$JBOSS_HOME/server/default//conf/JBOSS-service.xml中的设置之前，尝试Tiago的响应一直有效

您收到的错误仅仅是因为您在for循环中关闭了EntityManager。因此，当您第二次尝试调用

em.getDelegate（）

时，您的em已经关闭。不，您不想手动关闭它。你会有这样的想法：

session = (Session)em.getDelegate();
for (final Order order : results) { 
        ...                 
                    try { 

                        state = findStateByAbbrev(stateAbbrev, session);
                    } catch (HibernateException e) {
                        e.printStackTrace(System.err);
                        LOG.error(e.getMessage(), e);
                    } 

        }   // for

至于超时的问题，可能您正面临JPA和Hibernate之间的一个常见问题。看一看，这可能对你有帮助。也许问题在于您从EM获取Hibernate会话的方式。同样，也是关于相同的问题

---

如果这些都没有帮助，只需在下面写一条评论，或者编辑你的问题，指定超时时间

在我达到JBoss中的超时限制之前，您的建议一直有效，在这一点上，我得到一个“Transaction is not active:”异常（如上所述）。我该怎么做
