• 生产者配置

  设置生产者的输入输出通道

package net.happyeasygo.hotel.mq.interf;  import org.springframework.cloud.stream.annotation.Input; import org.springframework.cloud.stream.annotation.Output; import org.springframework.messaging.MessageChannel; import org.springframework.messaging.SubscribableChannel;  public interface OrderProcessor {     String INPUT_ORDER = "inputOrder";     String OUTPUT_ORDER = "outputOrder";      @Input(INPUT_ORDER)     SubscribableChannel inputOrder();      @Output(OUTPUT_ORDER)     MessageChannel outputOrder(); }

生产者发送消息

@EnableBinding(OrderProcessor.class) public class PayCallBackController{     @Autowired     private OrderProcessor orderProcessor;          public void payMethod(){         //该data可以为对象也可以为字符串         String data ="";         orderProcessor.outputOrder().send(MessageBuilder.withPayload(data).build());                }    }     //添加监听消息队列output通道     @StreamListener(OrderProcessor.INPUT_ORDER)     public void recevieOrder(String obj) {         _log.info("Interface order completion, message queue");     }

设置application.yml文件

spring:   cloud:     stream:       default-binder: rabbit       bindings:         inputOrder:           destination: mqSupplierOrder         outputOrder:           destination: mqSupplierOrder           content-type: application/json   rabbitmq:      host: ${RMQ_HOST:192.168.1.57}      port:  ${RMQ_PORT:5672}      username: ${RMQ_USERNAME:guest}     password: ${RMQ_PASSWORD:guest}

• 消费者配置

  设置消费者的输入输出通道

package net.happyeasygo.hotel.mq.interf;  import org.springframework.cloud.stream.annotation.Input; import org.springframework.cloud.stream.annotation.Output; import org.springframework.messaging.MessageChannel; import org.springframework.messaging.SubscribableChannel;  public interface OrderProcessor {     String INPUT_ORDER = "inputOrder";     String OUTPUT_ORDER = "outputOrder";      @Input(INPUT_ORDER)     SubscribableChannel inputOrder();      @Output(OUTPUT_ORDER)     MessageChannel outputOrder(); }

消费者消费消息

 @EnableBinding(OrderProcessor.class) public class OrderReceiver {      @StreamListener(OrderProcessor.INPUT_ORDER)     public void receiveMethod(String bookingNo) throws Exception{         strategyDida.book("strategyDida",bookingNo);     } }

application.yml配置

spring:   rabbitmq:      host: ${RMQ_HOST:192.168.1.57}      port:  ${RMQ_PORT:5672}      username: ${RMQ_USERNAME:guest}     password: ${RMQ_PASSWORD:guest}   cloud:     stream:       default-binder: rabbit       bindings:         inputOrder:           destination: mqSupplierOrder         outputOrder:           destination: mqSupplierOrder
