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。

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)
      }
  }

• 配置信息方式创建

  import (
      "log"
  
      devspore "github.com/huaweicloud/devcloud-go/sql-driver/mysql"
      "gorm.io/driver/mysql"
      "gorm.io/gorm"
  )
  var (
      DevSporeGorm *gorm.DB
      err error
  )
  func init() {
      devspore.SetClusterConfiguration(mysqlConfiguration())
      DevSporeGorm, err = gorm.Open(mysql.New(mysql.Config{DriverName: "devspore_mysql", DSN: ""}))
      if err != nil {
          log.Fatalln(err)
      }
  }
