kafka报错：Connection with localhost/127.0.0.1 disconnected java.net.ConnectException: Connection refus

报错情况：

虚拟机上服务器使用生产者和消费者以localhost可以发布消费消息，但是本机使用localhost报错！！！

解决方案：

设置kafka配置文件中的advertised.listeners属性！注意，该属性才是对应外网的监听属性！修改后：

# 允许外部端口连接
listeners=PLAINTEXT://:9092
# 外部代理地址
advertised.listeners=PLAINTEXT://192.168.130.130:9092

192.168.130.130是我虚拟机服务器自己的地址，可使用ifconfig命令查看

同时，本地java程序生产者设置的bootstrap.servers对应值也改为：192.168.130.130：9092

OK!!!
