錯誤如下：
11:57:24 [org.springframework.kafka.KafkaListenerEndpointContainer#0-0-C-1] WARN o.apache.kafka.clients.NetworkClient - [Consumer clientId=consumer-2, groupId=test_api] 3 partitions have leader brokers without a matching listener, including [test_topic_order-0, test_topic_goods-0, test_topic_refund-0]

用tail命令查看會發現日志在不停的刷上面內容，開始排查問題，最后定位在配置文件server.properties里面，通過網上一些文章，嘗試了一下
第一個：
把192.168.2.9改成localhost
試了之后，依然報錯：
11:57:00 [org.springframework.kafka.KafkaListenerEndpointContainer#0-0-C-1] WARN o.apache.kafka.clients.NetworkClient - [Consumer clientId=consumer-2, groupId=test_api] Connection to node 0 could not be established. Broker may not be available.

會發現報錯改變了，看來這么改不對，回頭想了下，首先排除ip和端口問題，然后想到會不會是參數哪里有問題，於是
| 參數 |
默認值 |
描述 |
| broker.id |
-1 |
每一個boker都有一個唯一的id作為它們的名字。當該服務器的IP地址發生改變時，broker.id沒有變化，則不會影響consumers的消息情況 |
| num.network.threads |
3 |
broker處理消息的最大線程數，一般情況下數量為cpu核數 |
| num.io.threads |
8 |
處理IO的線程數 |
| num.partitions |
1 |
默認分區數 |
發現參數也沒什么問題，接着往下看配置文件，看了下zookeeper連接，通過ps和netstat命令查到本機上有一個單台和一個由三台組成的zookeeper集群
更改了一下zookeeper，發現日志刷新錯誤變了，發現需要重啟服務，然后重新啟動后日志恢復正常
