Question

尝试使用kafka开发Spring Cloud应用程序

用于kafka的配置为：

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

运行该应用程序，我可以看到这些配置被提取

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

如何配置此“ AdminClient”并传递正确的主机/ ip信息？检查了Spring Cloud Stream Kafka Binder Reference Guide，但找不到答案。

因此，根据日志，已设置正确的配置，但这只是到代理的初始连接。然后，Kafka控制器将群集中每个代理的advertised.listener / 127.0.0.1列表发送回您的客户端，在大多数情况下，这些列表需要配置为客户端的外部地址。可以由外部客户解决的经纪人。如果您还有其他问题（在您的情况下，{{1}}），则需要检查该属性
