如何在 Activemq 中暂停队列

Question

我需要在应用程序内暂停 Activemq 5.13.2 中的队列，根据此 post 版本 5.12 是可能的，但我不知道如何实现它。任何 Java 代码示例都很棒。

@Test
public void testPauseQueue() throws Exception {
    JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi");
    JMXConnector jmxc = JMXConnectorFactory.connect(url);
    MBeanServerConnection conn = jmxc.getMBeanServerConnection();



    ObjectName queue = new ObjectName("org.apache.activemq:BrokerName=localhost,Type=Queue,Destination=testq");
    QueueViewMBean mbean = MBeanServerInvocationHandler.newProxyInstance(conn, queue,QueueViewMBean.class, true);
    System.out.println(mbean.isPaused());

}

异常

Answer 1

您可以使用表示要暂停的队列的 MBean 来执行此操作。因此，使用 JConsole 您将连接到代理，找到相关队列的 MBean 并对该队列执行 'pause' 操作，然后当您准备好再次让该队列开始发送消息时，您将执行'resume' 操作。

名字好像变了

  ObjectName queue = new ObjectName("org.apache.activemq:BrokerName=localhost,Type=Queue,Destination=testq");

到

  ObjectName queue = new ObjectName("org.apache.activemq:brokerName=localhost,destinationName=testq,destinationType=Queue,type=Broker");

修改后完美运行

我发现了 REST 管理的新名称格式 API http://activemq.apache.org/rest.html

如果使用 OpenEJB/TomEE，您可以使用 JConsole:

找到 MBean ObjectName 名称
