Java 增加一次处理的出列消息数（ActiveMQ）

我在JBoss AS7中运行了一个MDB，它使用ActiveMQ JCA资源适配器从远程ActiveMQ 5.6代理接收消息

生产商代码：

public void sendMessage(IDeliveryMessage message) throws Exception {

    Connection conn = null;
    Session session = null;
    MessageProducer producer = null;

    try {
        // Setup the connection & session
        ConnectionFactory cf = NamedObjectLocator.getConnectionFactory();
        conn = cf.createConnection();
        Destination destination = NamedObjectLocator.getDestination();
        session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
        conn.start();
        // Send a text message
        producer = session.createProducer(destination);
        ObjectMessage om = session.createObjectMessage(message);

        String id = System.currentTimeMillis()+"";
        om.setJMSCorrelationID(id);
        System.out.println("Producer: " + id);

        producer.send(om);

    } catch (Exception e) {
        throw new Exception(e.getMessage(), e);
    } finally {
        if (producer != null) {
            producer.close();
        }
        if (session != null) {
            session.close();
        }
        if (conn != null) {
            conn.stop();
            conn.close();
        }
    }
}

import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;

@MessageDriven(name = "OutBoundMDB", activationConfig = {
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
        @ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/OutboundIntegrationQueue")})
public class OutBoundMDB implements MessageListener {

    public static final long serialVersionUID = 8609676375853959140L;

    public void onMessage(Message message) {
        try {

            System.out.println("Consumer: " + message.getJMSCorrelationID());

            Thread.sleep(20000L);

        } catch (Exception e) {
            LogManager.logError(e);
        }

    }

}

消费者代码：

public void sendMessage(IDeliveryMessage message) throws Exception {

    Connection conn = null;
    Session session = null;
    MessageProducer producer = null;

    try {
        // Setup the connection & session
        ConnectionFactory cf = NamedObjectLocator.getConnectionFactory();
        conn = cf.createConnection();
        Destination destination = NamedObjectLocator.getDestination();
        session = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
        conn.start();
        // Send a text message
        producer = session.createProducer(destination);
        ObjectMessage om = session.createObjectMessage(message);

        String id = System.currentTimeMillis()+"";
        om.setJMSCorrelationID(id);
        System.out.println("Producer: " + id);

        producer.send(om);

    } catch (Exception e) {
        throw new Exception(e.getMessage(), e);
    } finally {
        if (producer != null) {
            producer.close();
        }
        if (session != null) {
            session.close();
        }
        if (conn != null) {
            conn.stop();
            conn.close();
        }
    }
}

public class OutBoundMDB implements MessageListener {

    public static final long serialVersionUID = 8609676375853959140L;

我希望一次退出队列的邮件数量（目前约为10条）增加到50条或更多。请查看。您几乎肯定需要调整

maxSessions

和

maxMessagesPerSession

以满足您的性能目标

---

您可能还需要调整容器维护的池中MDB实例的数量（在本例中为JBoss EAP）。在服务器配置中搜索

mdb strict max pool

。默认情况下，它从服务器的CPU计数导出池大小，但您可以使用

max pool size

显式设置它。我相信推导过程使用了以下公式：

Runtime.getRuntime（）.availableProcessors（）*4

（请参阅）。

您如何处理消息（例如MDB、standalone MessageConsumer、standalone MessageListener等）？你们有多少消费者？您是否已将ActiveMQ配置为在JBoss AS7中嵌入式运行，还是独立运行？您如何处理这些消息？MDB。。。你们有多少消费者？1.您是否已将ActiveMQ配置为在JBoss AS7中嵌入式运行，还是独立运行？未嵌入Jboss，它是独立运行的。如果您在Jboss AS7中运行一个MDB，它使用来自远程ActiveMQ 5.x代理的消息，那么我假设MDB使用的是ActiveMQ JCA资源适配器。如果正确，MDB的激活配置是什么？如果没有，请详细说明如何在JBoss AS7和ActiveMQ代理之间配置连接。另外，你不应该用你自己的评论来回答这些评论，而应该用额外的细节来编辑你的原始问题，这样问题就更全面、更容易回答。我已经重新表述了整个问题——希望这能更好地解释我的问题，并可能帮助我找到解决方案。谢谢
