通过将多个字段设为主键,以创建复合主键,例如:

    1. type Product struct {
      ID string `gorm:"primaryKey"`
      LanguageCode string `gorm:"primaryKey"`
      Code string
      Name string
      }

    注意:默认情况下,整型 PrioritizedPrimaryField 启用了 AutoIncrement,要禁用它,您需要为整型字段关闭 autoIncrement

    1. type Product struct {
      CategoryID uint64 `gorm:"primaryKey;autoIncrement:false"`
      TypeID uint64 `gorm:"primaryKey;autoIncrement:false"`
      }
