我们有一个生产者、一个消费者和一个分区。消费者/生产者都是spring引导应用程序。消费者应用程序在我的本地机器上运行，而生产者和kafka&zookeeper在远程机器上运行。
在开发过程中，我重新部署了producer应用程序，并做了一些更改。但在那之后，我的消费者没有收到任何信息。我尝试重新启动消费者，但没有成功。问题是什么和/或如何解决？
使用者配置：

spring:
  cloud:
    stream:
      defaultBinder: kafka
      bindings:
        input:
          destination: sales
          content-type: application/json
      kafka:
        binder:
          brokers: ${SERVICE_REGISTRY_HOST:127.0.0.1}
          zkNodes: ${SERVICE_REGISTRY_HOST:127.0.0.1}
          defaultZkPort: 2181
          defaultBrokerPort: 9092
server:
  port: 0

生产者配置：

cloud:
stream:
  defaultBinder: kafka
  bindings:
    output:
      destination: sales
      content-type: application/json
  kafka:
    binder:
      brokers: ${SERVICE_REGISTRY_HOST:127.0.0.1}
      zkNodes: ${SERVICE_REGISTRY_HOST:127.0.0.1}
      defaultZkPort: 2181
      defaultBrokerPort: 9092

5分钟后，消费者应用程序死亡，但以下情况除外：
