[Java]Springboot整合netty-soketio的最简易Demo

前端用soketio的话后端不能直接用netty了，不管怎么样先跑起来再想别的吧

线上测试地址为http://149.248.19.225:9092，不过不确定后期会不会被移除：）

给个index.html

 
  
  
  
  
 

Socket.io Test
Waiting for input
hello world!
Connect
Disconnect
Send Message

Spring-boot里

pom里

     
        
            com.corundumstudio.socketio
            netty-socketio
            1.7.17
        
        
            org.projectlombok
            lombok
            1.18.4
            provided
        

 直接用注释的话就不用改启动类了，所以直接给代码，配置也写代码不搞那么多乱七八糟的了，跑起来就即可
