formatter can't work well with lfshook and rotatelogs for logrus

[chjiyun]

        import (
              rotatelogs "github.com/lestrrat-go/file-rotatelogs"
	      "github.com/rifflock/lfshook"
              ...
         )

        Logger := logrus.New()
        file, err := os.OpenFile("app.log", os.O_RDWR|os.O_CREATE|os.O_APPEND, 0660)
        Logger.Out = io.MultiWriter(os.Stdout, file)
	logWriter, err := rotatelogs.New(
		// 分割后的文件名称
		fileName+".%Y%m%d.log",
		// 生成软链，指向最新日志文件
		rotatelogs.WithLinkName(fileName),
		// 设置最大保存时间(7天)
		rotatelogs.WithMaxAge(7*24*time.Hour),
		// 设置日志切割时间间隔(1天)
		rotatelogs.WithRotationTime(24*time.Hour),
	)
	if err != nil {
		panic(err)
	}
	writeMap := lfshook.WriterMap{
		logrus.InfoLevel:  logWriter,
		logrus.FatalLevel: logWriter,
		logrus.DebugLevel: logWriter,
		logrus.WarnLevel:  logWriter,
		logrus.ErrorLevel: logWriter,
		logrus.PanicLevel: logWriter,
	}
	lfHook := lfshook.NewHook(writeMap, &nested.Formatter{
		TimestampFormat: "2006-01-02 15:04:05",
		HideKeys: true,
	})
	// 新增 Hook
	Logger.AddHook(lfHook)

run the server and the result belows:

log print does not work well, no colors...
