Gin脚手架文件结构说明：

    conf/   #配置文件目录-下一层#环境文件夹

                /dev  #开发环境

                        base.toml*  #基本配置存储

                        mysql_map.toml*  #mysql配置存储

                        redis_map.toml*    #redis配置存储

    controller/   #控制器类-按照文件名区分不同的请求，同一请求汇聚到同一文件

    dao/    #数据访问的对象层-一般存储的是RM

    dto/    #数据传输对象层-输入的参数转化为实际的对象

    middleware/    #中间件层-日志的打印和请求的拦截，以及session和多语言的处理也可以放在这里

    public/    #公共层-放置一些公共的函数

    router/    #路由层-路由的配置请求的配置

    tmpl/        #模版文件存储位置

windows 也是这么输出mkdir -p $GOPATH/src/github.com/e421083458/gin_test_project吗?
