[ALI1416]

+1 问题解决了吗？

[KomachiSion]

从堆栈看起来， 是找不到类 io.grpc.netty.NettyChannelBuilder的报错， 同时堆栈的链路中没有看到和nacos有关的内容，应该和nacos client 以及logback-adapter没什么关系。

[firmianaQ]

+1 引入这个包就报错

[Lai-zw]

com.alibaba.nacos logback-adapter com.alibaba.nacos nacos-common 排除这个nacos-common依赖

[huangguangshan]

引入grpc-netty依赖就可以解决 。

这个报错的原因是因为gateway的GrpcSslConfigurer这个配置类被拉起来了。GrpcSslConfigurer用到了grpc-netty中的类，所以报错。

在gateway中有一个配置类grpcSslConfigurer。这个配置类的加载条件就是@ConditionalOnClass(name = "io.grpc.Channel")。nacos里面引入了grpc相关的类。导致了grpcSslConfigurer配置类被拉起。这个配置类中使用到了NettyChannelBuilder。NettyChannelBuilder为grpc-netty依赖中的类。而nacos并没有引入grpc-netty依赖。所以导致错误。
