Spring Cloud stream kafka绑定配置

Question

试图开发一个Spring云应用程序，使用kafka

Kafka使用的配置是：

spring:
  application:
    name: service-sample

  cloud:
    stream:
      bindings:
        output: 
          destination: lrctms-cloud-dev
          content-type: application/json

      kafka:
        binder:
          brokers: 192.168.11.153
          defaultBrokerPort: 9092
          zkNodes: 192.168.11.153

运行应用程序，我可以看到这些配置被选中

o.a.k.clients.admin.AdminClientConfig    : AdminClientConfig values:
      bootstrap.servers = [192.168.11.153:9092]
      client.id =
      connections.max.idle.ms = 300000
      metadata.max.age.ms = 300000
      metric.reporters = []
      metrics.num.samples = 2
      metrics.recording.level = INFO
      metrics.sample.window.ms = 30000
      receive.buffer.bytes = 65536
      reconnect.backoff.max.ms = 1000
      reconnect.backoff.ms = 50
      request.timeout.ms = 120000
      retries = 5
      retry.backoff.ms = 100
      sasl.jaas.config = null
      sasl.kerberos.kinit.cmd = /usr/bin/kinit
      sasl.kerberos.min.time.before.relogin = 60000
      sasl.kerberos.service.name = null
      sasl.kerberos.ticket.renew.jitter = 0.05
      sasl.kerberos.ticket.renew.window.factor = 0.8
      sasl.mechanism = GSSAPI
      security.protocol = PLAINTEXT
      send.buffer.bytes = 131072
      ssl.cipher.suites = null
      ssl.enabled.protocols = [TLSv1.2, TLSv1.1, TLSv1]
      ssl.endpoint.identification.algorithm = null
      ssl.key.password = null
      ssl.keymanager.algorithm = SunX509
      ssl.keystore.location = null
      ssl.keystore.password = null
      ssl.keystore.type = JKS
      ssl.protocol = TLS
      ssl.provider = null
      ssl.secure.random.implementation = null
      ssl.trustmanager.algorithm = PKIX
      ssl.truststore.location = null
      ssl.truststore.password = null
      ssl.truststore.type = JKS

问题是以下错误消息：

adminclient-1] o.apache.kafka.common.network.Selector   : [AdminClient clientId=adminclient-1] Connection with 127.0.0.1 disconnected
 java.net.ConnectException: Connection refused

如何配置这个“AdminClient”并将正确的主机/ip信息传递给它？查看了Spring Cloud Stream Kafka活页夹参考指南，但找不到答案。

因此，根据日志，设置了正确的配置，然而，这只是到代理的初始连接。Kafka控制器会将广告的列表发送回您的客户。主办姓名/广告。侦听器s，用于集群中的每个代理，在大多数情况下，需要将其配置为可由外部客户端解析的代理的外部地址。如果您正在获取任何其他信息（在您的情况下是127.0.0.1），则需要将其作为属性进行检查
