初学dubbo,在创建项目后运行时总报错java.lang.NoClassDefFoundError: io/netty/channel/nio/NioEventLoopGroup
找了半天资料,发现问题大致有
1、QoS无法启动(解决方案:https://www.cnblogs.com/LiangPF/p/11552560.html)
2、绑定端口被占用(解决方案:https://blog.csdn.net/HelloWorld998/article/details/94852083)
但是虽然错误信息都是Failed to bind NettyServer on ×××,cause: io/netty/bootstrap/ServerBootstrap,我的错误详细日志却显而易见是依赖未注入问题,后尝试添加netty的最新包,问题得以解决
附:阿里源Maven地址(https://maven.aliyun.com/mvn/search)
