java程序发送消息到服务器kafka连接不上问题

本文链接：https://blog.youkuaiyun.com/Sandul/article/details/128609848

这里的监听ip:端口如果写了localhost:9092,则java端写：

	//连接kafka
    properties.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,"192.168.1.207:9092");

在这里插入图片描述

如果发消息一直卡在连接，则说明连接不上，需要修改上图中的：

############################# Socket Server Settings #############################

# The address the socket server listens on. It will get the value returned from 
# java.net.InetAddress.getCanonicalHostName() if not configured.
#   FORMAT:
#     listeners = listener_name://host_name:port
#   EXAMPLE:
#     listeners = PLAINTEXT://your.host.name:9092
#listeners=PLAINTEXT://:9092

# Hostname and port the broker will advertise to producers and consumers. If not set, 
# it uses the value for "listeners" if configured.  Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
advertised.listeners=PLAINTEXT://192.168.1.207:9092

把相应的配置项：advertised.listeners 更改为具体的ip和端口号，或者java端和服务器端都用域名映射
