RabbitMQ之Topic交换器模式开发

Topic交换器，即主题模式，进行规则匹配。

一、Provider

配置文件

 spring.application.name=provider
 spring.rabbitmq.host=192.168.50.30
 spring.rabbitmq.port=5672
 spring.rabbitmq.username=rabbit
 spring.rabbitmq.password=rabbit
 #设置交换器名称
 mq.config.exchange=log.topic

代码

 public class UserSender {
     @Autowired
     private AmqpTemplate amqpTemplate;

     @Value("${mq.config.exchange}")
     private String exchange;

     public void send(String msg) {
         //交换器、路由键、消息
         this.amqpTemplate.convertAndSend(this.exchange, "user.log.debug", msg);
         this.amqpTemplate.convertAndSend(this.exchange, "user.log.info", msg);
     }

     public void send2(String msg) {
         this.amqpTemplate.convertAndSend(this.exchange, "product.log.debug", msg);
         this.amqpTemplate.convertAndSend(this.exchange, "product.log.info", msg);
     }
 }

二、Condumer

配置文件

 spring.appliction.name=consumer
 spring.rabbitmq.host=192.168.50.30
 spring.rabbitmq.port=5672
 spring.rabbitmq.username=rabbit
 spring.rabbitmq.password=rabbit
 #设置交换器名称
 mq.config.exchange=log.topic
 #info 队列名称
 mq.config.queue.info=log.info
 #error 队列名称
 mq.config.queue.error=log.error
 #log 队列名称
 mq.config.queue.logs=log.all

infoReceiver

 /**
     @RabbitListener bindings:绑定队列
     @QueueBinding value:绑定队列的名称
             exchange:配置交换器
     @Queue value:配置队列名称
             autoDelete:是否是一个可删除的临时队列
     @Exchange value:为交换器起个名称
             type:指定具体的交换器类型
 */
 @Component
 @RabbitListener(
     bindings=@QueueBinding(
         value=@Queue(
             value="${mq.config.queue.info}",
             autoDelete="true"
         ),
         exchange=@Exchange(
             value="${mq.config.exchange}",
             type=ExchangeTypes.TOPIC
         ),
         key="*.log.info"
     )
 )
 public class InfoReceiver {
     @RabbitHandler
     public void process(String msg){
         System.out.println(msg);
     }
 }

logsReceiver

     @Exchange value:为交换器起个名称
             type:指定具体的交换器类型
 */
 @Component

     bindings=@QueueBinding(
         value=@Queue(
             value="${mq.config.queue.logs}",

         ),
         exchange=@Exchange(
             value="${mq.config.exchange}",

     )

     public void process(String msg){
         System.out.println(msg);
     }
 }
