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：

}
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
