最近在使用plume log做日志系统时，发现如果使用kafka做消息队列时，会出现以下错误：
2020-07-21 14:15:29.571 WARN 13200 --- [ad | producer-1] org.apache.kafka.clients.NetworkClient : [Producer clientId=producer-1] Error connecting to node DESKTOP-HOS9DR7:9092 (id: 1 rack: null)

复制代码原因是kafka的配置问题：
原来的配置是：
listeners=PLAINTEXT://:9092
复制代码应该的配置是：
listeners=PLAINTEXT://10.80.122.224:9092
复制代码在一开始思考时，认为是和zookeeper设置有关，认为是和连接到本地的zookeeper有关，但其实是kafka设置存在问题，plume log应该没有走zookeeper去发现其他kafka服务
