dubbo项目启动报错:java.lang.NoClassDefFoundError: io/netty/channel/nio/NioEventLoopGroup

最近在做dubbo项目,今天升级了下dubbo的版本,然后就掉坑里去了,选择版本很重要啊啊啊......

错误描述:

java.lang.NoClassDefFoundError: io/netty/channel/nio/NioEventLoopGroup
   at com.alibaba.dubbo.qos.server.Server.start(Server.java:84)
   at com.alibaba.dubbo.qos.protocol.QosProtocolWrapper.startQosServer(QosProtocolWrapper.java:99)
   at com.alibaba.dubbo.qos.protocol.QosProtocolWrapper.export(QosProtocolWrapper.java:59)
   at com.alibaba.dubbo.rpc.protocol.ProtocolFilterWrapper.export(ProtocolFilterWrapper.java:98)
   at com.alibaba.dubbo.rpc.protocol.ProtocolListenerWrapper.export(ProtocolListenerWrapper.java:55)
   at com.alibaba.dubbo.rpc.Protocol$Adaptive.export(Protocol$Adaptive.java)
   at com.alibaba.dubbo.config.ServiceConfig.doExportUrlsFor1Protocol(ServiceConfig.java:515)
   at com.alibaba.dubbo.config.ServiceConfig.doExportUrls(ServiceConfig.java:360)
   at com.alibaba.dubbo.config.ServiceConfig.doExport(ServiceConfig.java:319)
   at com.alibaba.dubbo.config.ServiceConfig.export(ServiceConfig.java:217)
   at com.alibaba.dubbo.config.spring.ServiceBean.export(ServiceBean.java:266)
   at com.alibaba.dubbo.config.spring.ServiceBean.onApplicationEvent(ServiceBean.java:106)
   at com.alibaba.dubbo.config.spring.ServiceBean.onApplicationEvent(ServiceBean.java:53)

报错大概的意思是我dubbo版本升级后,缺少依赖,看了下资料,添加依赖就解决了:

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-all</artifactId>
    <version>4.1.32.Final</version>
</dependency>
