springboot集成kafka发消息报Exception thrown when sending a message with key= and payload=‘1’ to topic test

本地环境 springboot集成kafka发消息报错Exception thrown when sending a message with key='' and payload='1' to topic test

org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for test-0 due to 30049 ms has passed since batch creation plus linger time

错误排查：

2. 
   

Connection with /{内网ip} disconnected java.net.ConnectException: Connection timed out: no further information  Initiating connection to node 0 at {内网ip}:9092.

由此可见错误原因是本地无法访问服务器内网ip导致

解决办法：

修改kafka配置文件server.properties

listeners=PLAINTEXT://{内网ip}:9092

advertised.listeners=PLAINTEXT://{外网ip}:9092

重新启动本地项目，发送消息成功，并且DEBUG 日志级别下会打印心跳日志
