Log

var MainLogger *zap.Logger
var GatewayLogger *zap.Logger

func init() {

    MainLogger = NewLogger("./logs/main.log", zapcore.InfoLevel, 128, 30, 7, true, "Main")
    GatewayLogger = NewLogger("./logs/gateway.log", zapcore.DebugLevel, 128, 30, 7, true, "Gateway")
}

AppMain

func main() {
    fmt.Println("init main")
    log.MainLogger.Debug("hello main Debug")
    log.MainLogger.Info("hello main Info")
    log.GatewayLogger.Debug("Hi Gateway Im Debug")
    log.GatewayLogger.Info("Hi Gateway  Im Info")
}
