Question

我有一个spring-cloud-starter-bus-kafka项目，我在application.yml内设置了kafka网址，如下所示：

spring.kafka.bootstrap-servers=localhost:9092

这可以在本地部署kafka和zookeeper时找到，但是如果我将kafka和zookeeper移动到他们自己的服务器上，那么在spring-boot启动时会出现错误：

新配置

spring.kafka.bootstrap-servers=192.168.0.120:9092

错误

    "message" : "Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)",
    "logger_name" : "org.apache.zookeeper.ClientCnxn",
    "thread_name" : "main-SendThread(localhost:2181)",
    "level" : "INFO"
}

}

我应该如何配置kafka和zookeeper连接到他们的服务器？

Answer 1

您使用的是哪个版本？使用2.0时，不需要连接到zookeeper。

对于早期版本，您需要设置spring.cloud.stream.kafka.binder.zkNodes。

Spring Cloud Stream documentation here

Answer 2

Spring的文档中有关于此的部分：

https://docs.spring.io/spring-cloud-stream/docs/Ditmars.SR3/reference/htmlsingle/index.html#_kafka_binder_properties

您可以替换Application.yml上的默认URL

spring:
  cloud:
    stream:
      kafka:
        binder:
          zkNodes: ADDRESS:PORT
          brokers: ADDRESS:PORT

或使用.properties

spring.cloud.stream.kafka.binder.zkNodes = ADDRESS:PORT

为spring-cloud-bus设置zookeeper主机和端口
