这个库是 dubb-go 的底层库，所以不要引用 dubbo-go 的库， "dubbo.apache.org/dubbo-go/v3/common/logger" 这种形式的东西去掉，否则很容易造成循环依赖。你可以看下 “https://github.com/dubbogo/gost/blob/master/log/logger.go” 是否满足你的需要，如果不满足，可以去改进 dubbo-go 和 dubbo-getty 的共同的基础库 gost

调整了一版本，用了getty里面的logger，只要不注入logger的实例会用默认的zap log。PLAT @AlexStocks
