public class ConfigQueue {Value(${my_queue})private String myQueue;/*** 1.首先需要将队列注入springboot容器中** return*/Beanpublic Queue queue() {return new ActiveMQQueue(myQueue);}}

3.1 生产者截图 3.2 消费者截图 3.3 ActiveMQ后台截图 Number Of Consumers 消费者 这个是消费者端的消费者数量 ;Number Of Pending Messages 等待消费的消息 这个是当前未出队列的数量。可以理解为总接收数-总出队列数;Messages Enqueued 进入队列的消息 进入队列的总数量,包括出队列的。 这个数量只增不减 ;Messages Dequeued 出了队列的消息 可以理解为是消费这消费掉的数量 ;
