beego 使用连接mysql 报错 register db Ping `default`, default addr for network '123.56.95.103' unknown must have one register DataBase alias named `default

RT 按着官方文档，当连接一个已有的数据库时报 ``` register db Ping `default`, default addr for network '123.56.93.183' unknown must have one register DataBase alias named `default ``` 代码如下 ``` package main import ( _ "beetest/routers" "github.com/astaxie/beego" "github.com/astaxie/beego/orm" _ "github.com/go-sql-driver/mysql" ) func init() { orm.RegisterDriver("mysql", orm.DRMySQL) orm.RegisterDataBase("default", "mysql", "root:xxxxx@123.56.95.183/qianbao_test?charset=utf8") } func main() { orm.Debug = true o := orm.NewOrm() o.Using("qianbao_test") beego.Run() } ```
