Gin框架中间件日志重复：为什么我的日志出现了两份一样的记录？

// 日志记录到文件
func loggerMiddleware() gin.HandlerFunc {
    dir := file.GetPwd() // 使用GetPwd()
    logFilePath := fmt.Sprintf("%s/%s%s", dir, setting.AppSetting.RunTimeRootPath, setting.AppSetting.LogSavePath) // 使用AppSetting
    logFileName := "gin"

    // 日志文件路径
    filePath := path.Join(logFilePath, logFileName)
    fmt.Println("loggerMiddleware: " + filePath)

    // 创建文件，追加写入
    file, err := os.OpenFile(filePath, os.O_RDWR|os.O_CREATE|os.O_APPEND, 0777)
    if err != nil {
        fmt.Println("err", err)
        return func(c *gin.Context) {
            c.Next() // 确保请求继续处理
        }
    }
    defer file.Close() // 添加defer关闭文件

    logger := logrus.New()
    logger.SetLevel(logrus.DebugLevel)
    logger.Out = file

    // 使用rotatelogs进行日志分割
    logWriter, err := rotatelogs.New(
        filePath+".%Y-%m-%d.log",
        rotatelogs.WithLinkName(filePath),
        rotatelogs.WithMaxAge(7*24*time.Hour),
        rotatelogs.WithRotationTime(24*time.Hour),
    )
    if err != nil {
        fmt.Println("rotatelogs err:", err)
        return func(c *gin.Context) {
            c.Next()
        }
    }

    writeMap := lfshook.WriterMap{
        logrus.InfoLevel:  logWriter,
        logrus.FatalLevel: logWriter,
        logrus.DebugLevel: logWriter,
        logrus.WarnLevel:  logWriter,
        logrus.ErrorLevel: logWriter,
        logrus.PanicLevel: logWriter,
    }

    logger.AddHook(lfshook.NewHook(writeMap, &logrus.TextFormatter{
        TimestampFormat: "15:04:05",
    }))

    return func(c *gin.Context) {
        startTime := time.Now()
        c.Next()
        endTime := time.Now()
        logger.Infof("%3d | %8v | %13s | %s | %s | %s | %s | %s |",
            c.Writer.Status(),
            endTime.Sub(startTime),
            c.ClientIP(),
            c.Request.Method,
            c.Request.RequestURI,
            c.Request.Proto,
            c.Request.UserAgent(),
            c.Request.Referer(),
        )
    }
}
