### RabbitMQ 三种Exchange ###

Direct Exchange – 处理路由键

Fanout Exchange – 不处理路由键

Topic Exchange – 将路由键和某模式进行匹配

protected void initRabitMq(){
          String user = mqProperties.getProperty("rabbit.username");
          String pwd = mqProperties.getProperty("rabbit.pwd");
          String address = mqProperties.getProperty("rabbit.addresses");
    
          this.exchangeName = mqProperties.getProperty("rabbit.exchangeName");
          this.routingKey=mqProperties.getProperty("rabbit.routingKey");
          
          ExponentialBackOffPolicy policy = new ExponentialBackOffPolicy();
          policy.setInitialInterval(500);
          policy.setMaxInterval(5000);
          policy.setMultiplier(10);
          RetryTemplate retryTemplate = new RetryTemplate();
          retryTemplate.setBackOffPolicy(policy);
                
          CachingConnectionFactory factory = new CachingConnectionFactory();
          factory.setAddresses(address);
          factory.setUsername(user);
          factory.setPassword(pwd);
          
          RabbitTemplate rabbitTemplate = new RabbitTemplate();
          rabbitTemplate.setRetryTemplate(retryTemplate);
          rabbitTemplate.setConnectionFactory(factory);
    //    rabbitTemplate.setMessageConverter(new FastJsonMessageConverter());
          
          RabbitMqService rabmqService = new RabbitMqService();
          rabmqService.setRabbitTemplate(rabbitTemplate);
          mqService = rabmqService;
       }
       
       protected void initAliMnsMq(){
          String endpoint = mqProperties.getProperty("mns.accountendpoint");
          String accessId = mqProperties.getProperty("mns.accesskeyid");
          String accessSec = mqProperties.getProperty("mns.accesskeysecret");
                
          CloudAccount account = new CloudAccount(accessId,accessSec,endpoint);
          AliyunMnsService alimqService = new AliyunMnsService();
          alimqService.setMnsAccount(account);
          
          mqService = alimqService;
       }

配置：

#mq
    #if start mq sender
    mq.startSender=1
    #is start mq msg receiver
    mq.startConsumer=0
    
    #mq.type=rabbitmq
    mq.type=aliyunmns
    
    #queuename prefix
    mq.queueName=iuap-ys-queue
    
    #rabit,need when mq.type=rabbitmq
    rabbit.exchangeName=iuap-ys-exchange
    #rabbit routing key prefix
    rabbit.routingKey=iuap-ys-key
      
    rabbit.username=guest
    rabbit.pwd=guest
    rabbit.addresses=localhost:5672
    
    #mns,need when mq.type=aliyunmns
    #\u4e0b\u9762\u662f\u90a2\u52a0\u519b\u7684\u6d4b\u8bd5\u8d26\u53f7
    mns.accountendpoint=http://mns.cn.aliyuncs.com/
    mns.accesskeyid=000000000000
    mns.accesskeysecret=888888888888888888888888888888
