Java消息队列对比：
队列模式（queue）：平均接收消息生产者产生的消息
主题模式（topic）：全部接收生产者产生的所有消息，消费者必须要先预定主题，才能收到消息，没有预定的话是不能收到消息（也就是消费者无法消费产生在它启动接听之前的消息）
JMS编码接口之间的关系：
pom.xml:
AppConsumer:
AppProducer :
Spring jms :
- connectionFactory管理连接的连接工厂
- msTemplate用于发送和接受消息的模板
- messageListerner消息监听器
pom.xml:
common.xml:
consumer.xml:
producer.xml:
ConsumerMessageListener ：
ProducerServiceImpl :
其他与前者代码类似
