现象描述：
代码连接本地kafka没有问题 能监听到监听的topic，可获取通道中的所有topic
将kafka放到服务器上，本地程序启动报异常，可获取kafka中所有的topic，但是监听topic不起作用
启动时，报下面两个异常
Bootstrap broker localhost:9092 (id: -1 rack: null) disconnected
Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available.
解决方案：
kafka: TOPIC: 002 #kafka历史队列 TOPICH: 102 producer: bootstrap-servers: IP:端口 key-serializer: org.apache.kafka.common.serialization.IntegerSerializer value-serializer: org.apache.kafka.common.serialization.StringSerializer retries: 10 acks: all linger.ms: 1 batch.size: 16384 buffer.memory: 33554432 consumer: group-id: consumer-group auto-commit-interval: 1S auto-offset-reset: earliest enable-auto-commit: true key-deserializer: org.apache.kafka.common.serialization.StringDeserializer value-deserializer: org.apache.kafka.common.serialization.StringDeserializer在kafka 下面添加
kafka: bootstrap-servers: IP:端口,IP:端口,IP:端口问题解决
