一，官方网站:
https://gorm.io/如图:
二，安装:
从命令行安装gorm
$ go get -u gorm.io/gorm
go: downloading gorm.io/gorm v1.25.12
go: downloading github.com/jinzhu/now v1.1.5
go: downloading golang.org/x/text v0.19.0
go: downloading golang.org/x/text v0.20.0
go: added github.com/jinzhu/inflection v1.0.0
go: added github.com/jinzhu/now v1.1.5
go: upgraded golang.org/x/text v0.19.0 => v0.20.0
go: added gorm.io/gorm v1.25.12
安装相应的数据库驱动，我们这里选择mysql
$ go get -u gorm.io/driver/mysql
go: downloading gorm.io/driver/mysql v1.5.7
go: downloading github.com/go-sql-driver/mysql v1.7.0
go: downloading github.com/go-sql-driver/mysql v1.8.1
go: downloading filippo.io/edwards25519 v1.1.0
go: added filippo.io/edwards25519 v1.1.0
go: added github.com/go-sql-driver/mysql v1.8.1
go: added gorm.io/driver/mysql v1.5.7三，测试编写代码
1,建立连接:
package configimport ("fmt""gorm.io/driver/mysql""gorm.io/gorm""gorm.io/gorm/logger""time"
)var (DBLink *gorm.DB
)func SetupDBLink() (error) {var err errordsn := fmt.Sprintf("%s:%s@tcp(%s)/%s?charset=%s&parseTime=%t&loc=Local","username","password","127.0.0.1:3306","databasename","utf8",true, )//dsn:="username:password@tcp(127.0.0.1:3306)/basename?charset=utf8&parseTime=True&loc=Local";DBLink, err = gorm.Open(mysql.Open(dsn), &gorm.Config{Logger: logger.Default.LogMode(logger.Info),})//DBLink.Logger.LogMode(logger.Info)if err != nil {return err}sqlDB, _ := DBLink.DB()// SetMaxIdleConns 设置空闲连接池中连接的最大数量sqlDB.SetMaxIdleConns(10)// SetMaxOpenConns 设置打开数据库连接的最大数量sqlDB.SetMaxOpenConns(30)// SetConnMaxLifetime 设置了连接可复用的最大时间sqlDB.SetConnMaxLifetime(time.Hour)return nil
}
2,查询数据:
type Article struct {//定义文章的structId uint `gorm:"column:id;primaryKey"`Title string `gorm:"column:title;" json:"title"`Demo string `gorm:"column:demo;" json:"demo"`Content string `gorm:"column:content;" json:"content"`
}func (Article) TableName() string {return "article"
}func (dc *ArticleController) GetArticle(c *fiber.Ctx) error {fields := []string{"id", "title","demo","content"}articleOne:=&Article{}articleId := 2424articleOutOne:=&ArticleOut{}err := config.DBLink.Select(fields).Where("id=?",articleId).First(&articleOne).Errorif (err != nil) {fmt.Println(err)} else {fmt.Println(articleOne)}myMap:=fiber.Map{}myMap["Title"] = "书店新上图书列表"myMap["Article"] = articleOnefmt.Println(myMap)return c.Render("article/info", myMap)
}
