Short: "create an rpc application use hprose base on beego framework",
Long: `
create an rpc application use hprose base on beego framework
bee hprose [appname] [-tables=""] [-driver=mysql] [-conn=root:@tcp(127.0.0.1:3306)/test]
-tables: a list of table names separated by ',', default is empty, indicating all tables
-driver: [mysql | postgres | sqlite], the default is mysql
-conn: the connection string used by the driver, the default is ''
e.g. for mysql: root:@tcp(127.0.0.1:3306)/test
e.g. for postgres: postgres://postgres:postgres@127.0.0.1:5432/postgres
if conn is empty will create a example rpc application. otherwise generate rpc application use hprose based on an existing database.
In the current path, will create a folder named [appname]
In the appname folder has the follow struct:
├── conf
│ └── app.conf
├── main.go
