重试过期后如何从 JBoss 4.2.2 消息队列重新发送消息

发布于 2024-07-21 07:47:43 字数 142 浏览 12 评论 0原文

有没有办法重新发送 JBoss 4.2.2 消息队列中过期的消息？问题是他们超出了重试次数，但现在问题已经解决了，那么有没有办法重新发送呢？

在 JBoss 3 中，它们只是您可以移动的文本文件。现在它已经存储在数据库中了，你该怎么做呢？

看看 Hermes JMS。它是一个用于浏览 JMS 队列和主题的开源工具。它可以重播最终位于代理无法传递队列中的消息。

这就是我最终所做的：

    Hashtable t = new Hashtable();
    t.put(Context.PROVIDER_URL, "localhost:1099");
    t.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
    Context ctx = new InitialContext(t);
    Queue q = (Queue) ctx.lookup("/queue/DLQ");
    //----------------------------
    ConnectionFactory cf = (ConnectionFactory) ctx.lookup("/ConnectionFactory");
    Connection connection = cf.createConnection();
    Session session = connection.createSession(true, 0);
    //---------------------------------
    MessageConsumer consumer = session.createConsumer(q);
    connection.start();
    SpyObjectMessage m;

    Queue originialDestination = null;
//There can only be one in my case, but really you have to look it up every time.
    MessageProducer producer = null;
    while ((m = (SpyObjectMessage) consumer.receive(5000)) != null) {
        Object o = m.getObject();
        Date messageDate = new Date(m.getJMSTimestamp());
        String originalQueue = m.getStringProperty("JBOSS_ORIG_DESTINATION");
            if (originialDestination == null) {
                originialDestination = (Queue) ctx.lookup("/queue/" +
 originalQueue.substring(originalQueue.indexOf('.') + 1));
                producer = session.createProducer(originialDestination);
            }
            producer.send(session.createObjectMessage((Serializable) o));
      m.acknowledge();
    }
    //session.commit();    //Uncomment to make this real.
    connection.close();
    ctx.close();

This is what I ended up doing:

    Hashtable t = new Hashtable();
    t.put(Context.PROVIDER_URL, "localhost:1099");
    t.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
    Context ctx = new InitialContext(t);
    Queue q = (Queue) ctx.lookup("/queue/DLQ");
    //----------------------------
    ConnectionFactory cf = (ConnectionFactory) ctx.lookup("/ConnectionFactory");
    Connection connection = cf.createConnection();
    Session session = connection.createSession(true, 0);
    //---------------------------------
    MessageConsumer consumer = session.createConsumer(q);
    connection.start();
    SpyObjectMessage m;

    Queue originialDestination = null;
//There can only be one in my case, but really you have to look it up every time.
    MessageProducer producer = null;
    while ((m = (SpyObjectMessage) consumer.receive(5000)) != null) {
        Object o = m.getObject();
        Date messageDate = new Date(m.getJMSTimestamp());
        String originalQueue = m.getStringProperty("JBOSS_ORIG_DESTINATION");
            if (originialDestination == null) {
                originialDestination = (Queue) ctx.lookup("/queue/" +
 originalQueue.substring(originalQueue.indexOf('.') + 1));
                producer = session.createProducer(originialDestination);
            }
            producer.send(session.createObjectMessage((Serializable) o));
      m.acknowledge();
    }
    //session.commit();    //Uncomment to make this real.
    connection.close();
    ctx.close();
