golang xorm reverse 自动生成数据库实体文件

一、先安装好需要的东西

xorm

go get github.com/go-xorm/cmd/xorm

安装驱动版本,选择自己需要用的

go get github.com/go-sql-driver/mysql //Mysql
go get github.com/ziutek/mymysql/godrv //MyMysql
go get github.com/lib/pq //Postgres
go get github.com/mattn/go-sqlite3 //SQLite
go get github.com/denisenkom/go-mssqldb //MSSQL

二、配置%GOPATH%/Bin的环境变量

三、测试xorm cmd是否安装成功

xorm help reverse

xorm reverse命令参数如下所示

D:\MyConfiguration\xxx>xorm help reverse
usage: xorm reverse [-s] driverName datasourceName tmplPath [generatedPath] [tableFilterReg]
according database's tables and columns to generate codes for Go, C++ and etc.
 -s Generated one go file for every table
 driverName Database driver name, now supported four: mysql mymysql sqlite3 postgres
 datasourceName Database connection uri, for detail infomation please visit driver's project page
 tmplPath Template dir for generated. the default templates dir hasprovide 1 template
 generatedPath This parameter is optional, if blank, the default value is models, then will
 generated all codes in models dir
 tableFilterReg Table name filter regexp

注意的是下面指令中的templates/goxorm 指的是%GOPATH%/Src\github.com\go-xorm\cmd\xorm\templates\goxorm
如果是cd切换到了%GOPATH%/Src\github.com\go-xorm\cmd\xorm的目录,就可以使用下面的指令,否则tmplPath请填写完整路径。
参考案例:MSSQL

sqlite: xorm reverse sqite3 test.db templates/goxorm
mysql: xorm reverse mysql root:@/xorm_test?charset=utf8 templates/goxorm
mymysql: xorm reverse mymysql xorm_test2/root/ templates/goxorm
postgres: xorm reverse postgres "dbname=xorm_test sslmode=disable" templates/goxorm
mssql: xorm reverse mssql "server=127.0.0.1;user id=testid;password=testpwd;database=testdb" templates/goxorm

案例:MSSQL
方式一:建议指定generatedPath(如下例C:\temp) ,这样好找生成后的代码。

xorm reverse mssql "server=127.0.0.1;user id=sa;password=123456;database=shifenzheng" %GOPATH%\Src\github.com\go-xorm\cmd\xorm\templates\goxorm C:\temp

方式二:cd先切换到xorm/cmd/xorm文件夹下再执行

cd %GOPATH%/Src\github.com\go-xorm\cmd\xorm
xorm reverse mssql "server=127.0.0.1;user id=sa;password=123456;database=shifenzheng" templates\goxorm C:\temp

如图:
