## 遇到的问题:
1. java项目启动

① Factory method 'socketIOServer' threw exception; nested exception is java.lang.NoClassDefFoundError: io/netty/util/internal/logging/InternalLoggerFactory
② Caused by: java.lang.ClassNotFoundException: io.netty.util.NettyRuntime
解决方式安装依赖包
``
<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-common</artifactId>
    <<version>4.1.39.Final</version>
</dependency>
``

2. netty-socketio与socketio.js版本兼容
① [netty-socketio与socketio.js版本兼容](https://www.iteye.com/blog/shuzheng5201314-2442000)
解决方式:
[面前只支持 2.x 版本的 socket.io.js](https://github.com/socketio/socket.io-client/issues/1476)

3. socket 连接成功，但是 socket.io on 失效
连接路径写错了，自己坑自己啊。直接 ip+端口的，不应该加上其他路径

4. 观察者和订阅-发布的区别?
