# gorm
***创建gorm.io/gorm*** ***包gorm.DB数据源，进行mysql操作***。
依赖引入，配置文件或配置信息修改参考[原生DB](https://support.huaweicloud.com/devg-mas/mas-devg-0053.html)。
初始化创建gorm数据源DevSporeGorm，后续执行MySQL相关操作。
- 配置文件方式创建。
  ```
  import (
      "log"
      _ "github.com/huaweicloud/devcloud-go/sql-driver/mysql"
      "gorm.io/driver/mysql"
      "gorm.io/gorm"
  )
  var (
      DevSporeGorm *gorm.DB
      err error
  )
  func init() {
      DevSporeGorm, err = gorm.Open(mysql.New(
        mysql.Config{DriverName: "devspore_mysql", DSN: "./conf/resources/config_mysql.yaml"},
      ))
      if err != nil {
          log.Fatalln(err)
      }
  }
  ```
