golang框架如何轻松集成数据库？

package main

import (
    "database/sql"
    "fmt"
    "time"

    "github.com/go-xorm/xorm"
)

type User struct {
    Id        int64     `xorm:"pk autoincr"`
    Name      string    `xorm:"varchar(255) not null"`
    CreatedAt time.Time `xorm:"created"`
}

func main() {
    engine, err := xorm.NewEngine("mysql", "root:password@tcp(localhost:3306)/test")
    if err != nil {
        panic(err)
    }

    if err = engine.Sync2(new(User)); err != nil {
        panic(err)
    }

    user := &User{Name: "John"}
    if _, err = engine.Insert(user); err != nil {
        panic(err)
    }

    fmt.Println(user.Id)
}
