图片描述 order服务和configServer都已经连接到了rabbitMQ,
使用的springcloud版本时SR2
springCloudStream 的input 和output的值不一样
写了个发送端

@RestController
@Slf4j
public class TestStreamController {

    @Autowired
    StreamClient StreamClient;


    @RequestMapping("/sendMessage")
    public void process(){
        OrderMasterDTO orderMasterDTO = new OrderMasterDTO();
        orderMasterDTO.setBuyName("sssss");
        StreamClient.output().send(MessageBuilder.withPayload(orderMasterDTO).build());
    }
}

一个接收端

@Component
@EnableBinding(value = StreamClient.class)
@Slf4j
public class ReciveTest {


    @StreamListener("myMessage")
    @SendTo("myReciveMessage")
    public String receive(OrderMasterDTO orderMasterDTO){
        log.info("Receive:"+orderMasterDTO);
        System.out.println("Receive:"+orderMasterDTO);
        return "recive: ok!";
    }

}

发送消息错误：图片描述
rabbitMQ端接收不到消息？想请教一下！

已采纳

pom.xml cloud版本应该写在dependencyManagement里
@StreamListener(StreamClient.OUTPT) 参数是OUTPT才对，不是 INPUT

正确的pom.xml如下
