在查询许多资料后，整理了以下代码：
package config import ( "fmt" nested "github.com/antonfisher/nested-logrus-formatter" "github.com/lestrrat-go/file-rotatelogs" "github.com/rifflock/lfshook" "github.com/sirupsen/logrus" "path/filepath" "runtime" "time" ) var ( Log *logrus.Logger ) func InitLogger() { Log = logrus.New() hook := NewLfsHook(filepath.Join(Cf.Logger.Path, "pack"), 0, 5) Log.AddHook(hook) Log.SetFormatter(formatter(true)) Log.SetReportCaller(true) } func formatter(isConsole bool) *nested.Formatter { fmtter := &nested.Formatter{ HideKeys: true, TimestampFormat: "2006-01-02 15:04:05", CallerFirst: true, CustomCallerFormatter: func(frame *runtime.Frame) string { funcInfo := runtime.FuncForPC(frame.PC) if funcInfo == nil { return "error during runtime.FuncForPC" } fullPath, line := funcInfo.FileLine(frame.PC) return fmt.Sprintf(" [%v:%v]", filepath.Base(fullPath), line) }, } if isConsole { fmtter.NoColors = false } else { fmtter.NoColors = true } return fmtter } func NewLfsHook(logName string, rotationTime time.Duration, leastDay uint) logrus.Hook { writer, err := rotatelogs.New( // 日志文件 logName+".%Y%m%d%H%M%S", // 日志周期(默认每86400秒/一天旋转一次) //rotatelogs.WithRotationTime(rotationTime), // 清除历史 (WithMaxAge和WithRotationCount只能选其一) //rotatelogs.WithMaxAge(time.Hour*24*7), //默认每7天清除下日志文件 rotatelogs.WithRotationCount(leastDay), //只保留最近的N个日志文件 ) if err != nil { panic(err) } // 可设置按不同level创建不同的文件名 lfsHook := lfshook.NewHook(lfshook.WriterMap{ logrus.DebugLevel: writer, logrus.InfoLevel: writer, logrus.WarnLevel: writer, logrus.ErrorLevel: writer, logrus.FatalLevel: writer, logrus.PanicLevel: writer, //}, &logrus.JSONFormatter{TimestampFormat: "2006-01-02 15:04:05"}) }, formatter(false)) return lfsHook }终端输出样式：
日志文件输出样式：
