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

1 spring.application.name=provider 2 spring.rabbitmq.host=192.168.50.30 3 spring.rabbitmq.port=5672 4 spring.rabbitmq.username=rabbit 5 spring.rabbitmq.password=rabbit 6 #设置交换器名称 7 mq.config.exchange=log.topic

代码

 1 public class UserSender {  2     @Autowired  3     private AmqpTemplate amqpTemplate;  4   5     @Value("${mq.config.exchange}")  6     private String exchange;  7   8     public void send(String msg) {  9         //交换器、路由键、消息 10         this.amqpTemplate.convertAndSend(this.exchange, "user.log.debug", msg); 11         this.amqpTemplate.convertAndSend(this.exchange, "user.log.info", msg); 12     } 13  14     public void send2(String msg) { 15         this.amqpTemplate.convertAndSend(this.exchange, "product.log.debug", msg); 16         this.amqpTemplate.convertAndSend(this.exchange, "product.log.info", msg); 17     } 18 }

二、Condumer

配置文件

 1 spring.appliction.name=consumer  2 spring.rabbitmq.host=192.168.50.30  3 spring.rabbitmq.port=5672  4 spring.rabbitmq.username=rabbit  5 spring.rabbitmq.password=rabbit  6 #设置交换器名称  7 mq.config.exchange=log.topic  8 #info 队列名称  9 mq.config.queue.info=log.info 10 #error 队列名称 11 mq.config.queue.error=log.error 12 #log 队列名称 13 mq.config.queue.logs=log.all
