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:

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

答案 0 :(得分：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。
