golang xorm reverse 自动生成数据库实体文件

Posted 2021-01-02 nickchou

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:MyConfigurationxxx>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%/Srcgithub.comgo-xormcmdxorm emplatesgoxorm
如果是cd切换到了%GOPATH%/Srcgithub.comgo-xormcmdxorm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: emp） ，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%Srcgithub.comgo-xormcmdxorm	emplatesgoxorm  C:	emp

方式二：cd先切换到xorm/cmd/xorm文件夹下再执行

cd %GOPATH%/Srcgithub.comgo-xormcmdxorm
xorm reverse mssql "server=127.0.0.1;user id=sa;password=123456;database=shifenzheng" templatesgoxorm  C:	emp

如图：
