kafka生产报错couldn‘t resolve server 9092 from bootstrap.servers as DNS

报错：

couldn't resolve server 9092 from bootstrap.servers as DNS

我的环境：

kafka配置的是ip

连接的配置：yml

kafkaduceconfig:

servers: node11:9092

修改后：

kafkaduceconfig:

servers: IP:9092

分析：因为hosts配置没有问题，可能是配置kafka的时候写的是ip地址，在代码访问的时候，hostname 不识别。改为ip地址就可以了
