Java 将spring云版本从Camden.SR4升级到Camden.SR5后，Dispatcher没有订阅服务器错误

霉菌代码： 1.1通道接口

 public interface MessageChanelInterface {

        String DEVICE_SINK = "device-sink";

        @Input(DEVICE_SINK)
        SubscribableChannel receiveDeviceEvent();}

---

2.听众

@Service
public class SubscriberToDevice {

      @Autowired
      ParkingService parkingService;

      @StreamListener(MessageChanelInterface.DEVICE_SINK)
      public void receiveDeviceEvent(Object event) {
          //Some code what to do with event.
      }
}

---

3.夏奈尔装订

@Configuration

   @EnableBinding(MessageChanelInterface.class)

   public class MessageChanelConfiguration {

}

---

4.代理绑定和通道配置

spring.cloud.stream.binders.rabbit1.type=rabbit
spring.cloud.stream.binders.rabbit1.environment.spring.rabbitmq.addresses=${_rabbit.host}
spring.cloud.stream.binders.rabbit1.environment.spring.rabbitmq.port=5672
spring.cloud.stream.binders.rabbit1.environment.spring.rabbitmq.username=${_rabbit.username}
spring.cloud.stream.binders.rabbit1.environment.spring.rabbitmq.password=${_rabbit.password}
spring.cloud.stream.bindings.device-sink.binder=rabbit1
spring.cloud.stream.bindings.device-sink.destination=device
spring.cloud.stream.bindings.device-sink.group=group-${spring.application.name}

虽然我使用的是spring云版本Camden.SR4，但在收到一些消息时没有错误消息。在收到消息后升级到Camden.SR5版本后，我收到了此错误消息。我已配置发布者，他发布消息时没有错误。顺便说一下，发布服务器配置是：

spring.cloud.stream.bindings.device-source.binder=rabbit1
spring.cloud.stream.bindings.device-source.destination=device

Brooklyn.SR2（spring cloud Camden.SR5中的版本spring.cloud.stream）的订户配置是否有重大变化？因为出版商工作得很好。在spring.cloud.stream Brooklyn.SR2的描述中，我没有看到订户配置有任何变化。一些解决方案如何修复它

错误消息

布鲁克林.SR1和Brooklyn.SR2之间存在一个已知的回归，这是由于一些内部重构

一种解决方法是使用与

对象

不同的参数类型（无论如何，为了获得类型强制的好处，我们建议这样做）

由于这是在Brooklyn.SR3之后发现的，所以可能需要等到Brooklyn.S4或更高版本的Camden来处理。或者，你可以考虑升级到CelSEA.RC1，它刚刚被发布（计划在星期一发布，在DalSTON中发布，在春云中发布）。

编辑：关于升级到Chelsea版本的快速说明-它需要启动1.5，所以YMMV在那里

我相信Camden.SR6Camden.SR6中有一个修复程序不起作用。首先，我尝试Camden.SR6，因为我有spring boot的1.4.5.RELEASE版本，并且推荐此spring boot的spring cloud版本为Camden.SR6。但是，Camden.SR6和Camden.SR5版本对我来说并不正确。谢谢您的回答。
