启动类AppQueueCustomer

启动后访问（ActiveMQ必须提前启动）

http://localhost:8042/doc.html

现在进行测试，在生产端程序发送数据，可以看到消费端收到了数据并临时保存在列表里

![e772539998c4434386d0c07accb12ae9.png][]

还可以使用List<String> 或者 List<Object> 或者直接java对象

测试下对象

消费端接收的数据

![17eb26699e1647c99f02646def6ea906.png][]

另外可以在控制台看到

![2da96b27f9604df1ac7fa560a29c0a5c.png][]

A和B两个接收监听都收到了数据，看着像是轮询消费的，**ActiveMQ支持存在多个消费者，但是对一个消费者而言，只会有一个消费者可以消费，其他的消费者便不能消费此消息**

还有ActiveMQ默认开启持久化的，数据在安装目录的data目录下面
