如何在Activemq中暂停队列

Question

我需要在应用程序内的Activemq 5.13.2中暂停一个队列，根据这篇文章https://stackoverflow.com/a/32165140/1458556，它可能是5.12版本，但我不知道如何实现它。任何Java代码示例都会很棒。

@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

Caused by: javax.management.InstanceNotFoundException: org.apache.activemq:BrokerName=localhost,Type=Queue,Destination=testq

Answer 1

似乎名称已从

更改

  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");

然后在改变后完美地工作。

我发现了使用REST管理API http://activemq.apache.org/rest.html

的新名称格式

如果使用OpenEJB / TomEE，您可以使用JConsole找到MBean ObjectName名称：
