// GetConf gets configuration instance
func GetConf() *Config {
	once.Do(initConf)
	return conf
}

func initConf() {
	config := viper.New()
	prefix := "conf"
	confFileRelPath := filepath.Join(prefix, filepath.Join(GetEnv(), "conf.yaml"))
	config.SetConfigFile(confFileRelPath)
	if err := config.ReadInConfig(); err != nil {
		panic(err)
	}
	
	conf = new(Config)
	conf.Env = GetEnv()
	if err := config.Unmarshal(conf); err != nil {
		panic(err)
	}
	if err := validator.Validate(conf); err != nil {
		panic(err)
	}
}

func GetEnv() string {
	e := os.Getenv("GO_ENV")
	if len(e) == 0 {
		return "test"
	}
	return e
}

func LogLevel() hlog.Level {
	level := GetConf().Hertz.LogLevel
	switch level {
	case "trace":
		return hlog.LevelTrace
	case "debug":
		return hlog.LevelDebug
	case "info":
		return hlog.LevelInfo
	case "notice":
		return hlog.LevelNotice
	case "warn":
		return hlog.LevelWarn
	case "error":
		return hlog.LevelError
	case "fatal":
		return hlog.LevelFatal
	default:
		return hlog.LevelInfo
	}
}

Expected Behavior

When the value of the bool type in the Hertz struct is true, it should be true in conf.

Actual Behavior

The value of the bool type in the Hertz struct witch in conf is false, but the value in yaml and viper is true.

You need to use mapstructure struct tags, not yaml.
