五、ActiveMQ添加了mysql的持久化后，发了消息，但是MSGS表中没有记录.

1.持久化以后 activemq数据库会创建3张表

</bean>

在 producer 生产者中需要设置

            producer.setDeliveryMode(DeliveryMode.PERSISTENT);
//            producer.setTimeToLive(10);

//            发送
            producer.send(textMessage);
//            producer.send(textMessage, DeliveryMode.PERSISTENT, 1, 60 * 60 * 24);

在consumer 消费者中添加注意设置客户端id 需要在开启链接前面

//设置客户端id

 //设置客户端id
connection.setClientID("client-1");

connection.start();

//            final MessageConsumer messageConsumer = session.createConsumer(topic);//普通订阅
         MessageConsumer messageConsumer = session.createDurableSubscriber(topic,"bb"); //持久订阅
