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?charset=utf-8" 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
依赖包：https://github.com/robfig/cron
补充： golang xorm Model 模型文件模板
* Record.go
