使用 JMSQueueControl 暂停和恢复 JMS 消息的任何示例

Question

I read in the activeMQ documentation that we can pause and resume JMS message using JMSQueueControl but not able to find the interface in the latest jars.

https://activemq.apache.org/components/artemis/documentation/1.1.0/management.html

Any code example would be appreciated.

According to the documentation, you can use QueueControl and there is such a class in the API.

Pausing and resuming Queues

The QueueControl can pause and resume the underlying queue. When a queue is paused, it will receive messages but will not deliver them. When it's resumed, it'll begin delivering the queued messages, if any.

Example of Usage:

String eapObjectName = "org.apache.activemq.artemis:broker=\"default\",component=addresses,address=\"jms.queue.exampleQueue\",subcomponent=queues,routing-type=\"anycast\",queue=\"jms.queue.exampleQueue\"";
MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer();
ObjectName objectName = ObjectName.getInstance(eapObjectName);
QueueControl queueControl = MBeanServerInvocationHandler.newProxyInstance(mBeanServer,objectName,QueueControl.class,false)



queueControl.pause();
