RabbitMQ之Direct交换器模式开发

Dirtct交换器，即发布与订阅模式，匹配规则为完全匹配。

　

一、Provideer

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
 #设置交换器的名称
 mq.config.exchange=log.direct
 #info 路由键
 mq.config.queue.info.routing.key=log.info.routing.key
 #error 路由键
 mq.config.queue.error.routing.key=log.error.routing.key
 #error 队列名称
 mq.config.queue.error=log.error

代码

 @Component
 public class Sender {
     @Autowired
     private AmqpTemplate amqpTemplate;

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

     @Value("${mq.config.queue.error.routing.key}")
     private String routingkey;

     public void send(String msg) {
         this.amqpTemplate.convertAndSend(this.exchange, this.routingkey, msg);
     }
 }

二、consumer

配置文件

 spring.application.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.direct
 #info队列名称
 mq.config.queue.info=log.info
 #info路由键
 mq.config.queue.info.routing.key=log.info.routing.key
 #error队列名称
 mq.config.queqe.error=log.error
 #errot路由键
 mq.config.queue.error.routing.key=log.error.routing.key

1，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.DIRECT
         ),
         key="${mq.config.queue.info.routing.key}"
     )
 )
 public class Consumer {
     @RabbitHandler
     public void process(String msg) {
         System.out.println("info received:" + msg);
     }
 }

2，ErrorReceiver

 /*

 @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:为具体交换器起个名称
         type:指定具体的交换类型
  */
 @Component
 @RabbitListener(
     bindings=@QueueBinding(
         value=@Queue(
             value="${mq.config.queue.error}",
             autoDelete="true"
         ),
         exchange=@Exchange(
             value="${mq.config.exchange}",
             type=ExchangeTypes.DIRECT
         ),
         key="${mq.config.queue.error.routing.key}"
     )
 )
 public class ErrorReceiver {
     public void process(String msg) {
         System.out.println("error recevied:" + msg);
     }
 }
