## 工程架构 ##

基于dubbo的extension模块和分层的代码设计(包括 protocol layer, registry layer, cluster layer, config 等等)。我们的目标是:你可以对这些分层接口进行新的实现,并通过调用 extension 模块的“ extension.SetXXX ”方法来覆盖 dubbo-go [同 go-for-apache-dubbo ]的默认实现,以完成自己的特殊需求而无需修改源代码。同时,欢迎你为社区贡献有用的拓展实现。

![框架设计](https://raw.githubusercontent.com/wiki/dubbo/dubbo-go/dubbo-go%E4%BB%A3%E7%A0%81%E5%88%86%E5%B1%82%E8%AE%BE%E8%AE%A1.png)

关于详细设计请阅读 [code layered design](https://github.com/apache/dubbo-go/wiki/dubbo-go-V1.0-design)
