golang访问数据库记录SQL语句:

使用的包为:

1:github.com/arthurkiller/rollingwriter //写入日志包

2: github.com/go-xorm/xorm //xorm包

具体实现为:

package main 
import (
 "time"
 
 "github.com/arthurkiller/rollingwriter"
 _ "github.com/go-sql-driver/mysql"
 "github.com/go-xorm/xorm"
)
 
func main() {
 var conn string = "root:123456@tcp(127.0.0.1)/logsdemo"
 Engine, err := xorm.NewEngine("mysql", conn)
 if err != nil {
 panic("mysql connect fail")
 }
 config := rollingwriter.Config{
 LogPath: "./logs", //日志路径
 TimeTagFormat: "060102150405", //时间格式串
 FileName: "mysql_exec", //日志文件名
 MaxRemain: 3,  //配置日志最大存留数
 RollingPolicy: rollingwriter.VolumeRolling, //配置滚动策略 norolling t 
 imerolling volumerolling
 RollingTimePattern: "* * * * * *",  //配置时间滚动策略
 RollingVolumeSize: "1M",   //配置截断文件下限大小
 WriterMode: "none",
 BufferWriterThershould: 256,
 // Compress will compress log file with gzip
 Compress: true,
 }
 
 writer, err := rollingwriter.NewWriterFromConfig(&config)
 if err != nil {
 panic(err)
 }
 
 var logger *xorm.SimpleLogger = xorm.NewSimpleLogger(writer) 
 Engine.SetLogger(logger)
 Engine.ShowSQL(true) 
 logger.Info("ts info code") 
 Engine.Exec("select * from cp_order where id = ", 3)
 time.Sleep(1 * time.Second)
 
}

rollingwriter 实现一个 io.Writer传入到xorm.NewSimpleLogger 中 在xorm中实现日志的写入,在rollingwriter中保存日志到文件中

补充: golang xorm Model 模型文件模板

* Record.go

package models 
import (
 "fmt"
 "github.com/go-xorm/xorm"
 "time"
)
 
// 用户首次登录
type FirstLoginRecord struct {
 Id int64 `xorm:"not null pk autoincr INT(11)"`
 UserID int64 `json:"userid" xorm:"int(11) not null 'userid'"`
 IP string `json:"logonip" xorm:"varchar(45) not null 'logonip'"`
 CreatedAt time.Time `json:"logontime" xorm:"timestamp not null 'logontime'"`
 UpdatedAt time.Time `json:"logofftime" xorm:"timestamp not null 'logofftime'"`
 Source int `json:"source" xorm:"tinyint(3) not null"`
 IsCharged int `json:"ischargeaccount" xorm:"tinyint(3) unsigned not null 'ischargeaccount'"`
}
 
func (*FirstLoginRecord) TableName() string {
 return "W_UserFirstLogonRec"
}
 
func (*FirstLoginRecord) DB() *xorm.Engine {
 return DbDefault()
}
 
func (t *FirstLoginRecord) Save() error {
 var err error
 var engine = t.DB()
 if t.Id == 0 {
 t.Id, err = engine.Insert(t)
 return err
 }
 var rowsAffected int64
 rowsAffected, err = engine.Id(t.Id).Update(t)
 fmt.Printf("@table: %s: %d rows affected", t.TableName(), rowsAffected)
 return err
}
 
// 用户id唯一约束
func (this *FirstLoginRecord) AddDistinct() error {
 var err error
 var engine = this.DB()
 var has bool
 var ent = FirstLoginRecord{UserID: this.UserID }
 has, err = engine.Get(&ent)
 if has {
 return nil
 }
 this.Id, err = engine.Insert(this)
 return err
}
