我正在尝试在集群环境中构建 spring config 客户端，为此我正在使用kafka它来连接客户端。我的客户端项目与本地kafka服务器一起使用，但是当我尝试连接到我的远程kafka服务器应用程序时，请不要启动并抛出以下错误，

2019-01-09 00:06:00.364  INFO 17892 --- [           main] o.a.kafka.common.utils.AppInfoParser     : Kafka version : 2.0.1

在pom.xml,

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-bus-kafka</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>
