增加一次处理的出列消息数（ActiveMQ）

标签： java jboss activemq

我在JBoss AS7中运行了一个MDB，使用ActiveMQ JCA资源适配器消耗来自远程ActiveMQ 5.6代理的消息。

制作人代码： 

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();
        }
    }
}

消费者代码： 

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);
        }

    }

}

JBoss Standalone.xml： 

<subsystem xmlns="urn:jboss:domain:resource-adapters:1.0">
    <resource-adapters>
        <resource-adapter>
            <archive>

            </admin-objects>
        </resource-adapter>
    </resource-adapters>
</subsystem>

现在打印的日志显示Queue一次只能出列大约8到10条消息。由于我在消费者代码中让线程休眠了20秒，因此它只能处理约。 10条消息，然后是20秒的间隙，然后是10条消息。以下是显示结果的日志：

我希望一次将出列消息的数量（现在约为10）增加到50或更多。

答案 0 :(得分：0)

看看the ActiveMQ JCA RA activation specification documentation。您几乎肯定需要调整maxSessions和maxMessagesPerSession以符合您的效果目标。

您可能还需要调整容器维护的池中的MDB实例数（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数量派生池大小，但您可以使用max-pool-size显式设置它。我相信推导使用公式：Runtime.getRuntime().availableProcessors() * 4（参见here）。
