go gorm 配置日志

	newLogger := logger.New(log.New(os.Stdout, "\r\n", log.LstdFlags), logger.Config{
		SlowThreshold:        time.Second,  // 满阈值
		Colorful:             true, // 日志颜色开启
		ParameterizedQueries: false, // sql参数可见,true就是?
		LogLevel:             logger.Info, //日志级别
	})

// 连接mysql并配置日志信息
	DB, _ = gorm.Open(mysql.Open(viper.GetString("gin.datasource.url")), &gorm.Config{
		Logger: newLogger,
	})
