我是Hibernate的新手.

我试图编写一个小程序来将数据插入到mysql数据库服务器中.

这是我的程序的源代码:

private int insertRelateNew(int newId, List<DocSimilar> relateNews) {
    Session session = HibernateUtils.currentSession();
    Transaction tx = session.beginTransaction();
    RelatedArticles relatedArticles = null;
    try {
        relatedArticles = new RelatedArticles();
        for (DocSimilar doc : relateNews) {
            ApplicationPK appPK = new ApplicationPK(newId,
                    (int) doc.getDocid());
            relatedArticles.setApplicationPK(appPK);
            relatedArticles.setRelated_score(doc.getPercent());
            session.save(relatedArticles);
            tx.commit();
            session.flush();
        }
    } catch (Exception e) {
        e.printStackTrace();
        tx.rollback();
    }
    return newId;
}

运行时,它插入成功但有时它抛出一个TransactionException.

这是异常控制台:

org.hibernate.TransactionException: Transaction not successfully started
    at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:131)
    at com.ant.crawler.dao.hibernate.SqlNewsPersistencer.insertRelateNew(SqlNewsPersistencer.java:56)
    at com.ant.crawler.dao.hibernate.SqlNewsPersistencer.insertNews(SqlNewsPersistencer.java:40)

    at com.ant.crawler.core.Worker.run(Worker.java:14)
    at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)
    at …

我编写了一个在服务器上运行的Java服务.

我使用JMX并jconsole监控来自myPC的服务.

为了连接,我必须将以下链接复制并粘贴到jconsole:

service:jmx:rmi://192.168.5.207:9999/jndi/rmi://192.168.5.207:9999/jmxrmi

退出后jconsole,如果我想重新连接,我必须再次复制并粘贴链接.

有没有办法保存链接,jconsole以便我可以重用它？

或者你可以建议另一个远程监控工具.
