Spring Cloud Kafka Stream无法创建Producer配置错误

Question

我有两个带有Kafka-stream依赖项的Spring启动项目，它们在gradle和完全相同的配置中具有完全相同的依赖关系，但是启动时项目之一的日志错误如下所示

我使用的是kotlin 2.30和Spring Release 2.0.0.0 我的构建gradle的相关部分位于

之下

ext {
    kotlinVersion = '1.2.30'
    springBootVersion = '2.0.0.RELEASE'
    springCloudVersion = 'Finchley.M8'
}

dependencies{
  compile('org.springframework.cloud:spring-cloud-starter-stream-kafka')
}

我已经定义了一个OutPut频道，如下所示

interface EventStream {

    @Output("createschedule")
    fun outputEvent(): MessageChannel

}

下面是我的代码的relvant部分，其中我定义了发件人和监听器

@Service
class TestService {



    @Autowired
    private lateinit var eventStream: EventStream

    fun test() {
        processSchedule("Hello")
    }






    @SendTo("createschedule")
    fun processSchedule(campaign: String): String {
        return campaign
    }

    @StreamListener("createschedule")
    fun listenSchedule(campaign: String) {
        println(campaign)
        //return campaign
    }

}

以下是我的应用程序的相关部分.yaml

spring:
  cloud:
    stream:
      kafka:
        binder:
          brokers: ${KAFKA_IP}
          defaultBrokerPort: ${KAFKA_PORT}
          zkNodes: ${ZK_IP}
          defaultZkPort: ${ZK_PORT}
        bindings:
          createschedule:
            group: createscheduleGroup
            destination: createschedule
            consumer:
              group: createscheduleGroup



  kafka:
    admin:
      properties:
        #security.protocol: SSL
        client.id: client

正如我已经说过的那样，它在启动时抛出错误，并且在启动之后它会继续在日志中抛出错误

Answer 1

这是kafka的问题。 如果您使用的是docker cointainer，则停止kafka，移除kafka并启动kafka cointainer。
