生产者:

//步骤一:创建连接工厂

//步骤二:创建连接
Connection connection = activeMQConnectionFactory.createConnection();
//步骤三:启动连接
connection.start();
//步骤四:获取会话工厂
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
//步骤五:创建队列
Queue queue = session.createQueue("wdksoft_queue");
//创建消息生产者
MessageProducer producer = session.createProducer(queue);
//消息持久化
producer.setDeliveryMode(2);
//模拟消息
