数据库orm我选用xorm。首先在config.json和config.go添加对应的数据库配置。
config.json:

  "db_config": {
    "db_host": "127.0.0.1",
    "db_port": "3306",
    "db_user": "root",
    "db_password": "123456",
    "db_name": "test"
  }

config.go

type DBConfig struct {
	DbHost     string `json:"db_host"`
	DbPort     string `json:"db_port"`
	DbUser     string `json:"db_user"`
	DbPassword string `json:"db_password"`
	DbName     string `json:"db_name"`
}

接着，初始化数据库：

package db

import (
	"github.com/TomatoMr/awesomeframework/config"
	_ "github.com/go-sql-driver/mysql"
	"github.com/go-xorm/xorm"
	"github.com/pkg/errors"
)

var engine *xorm.Engine

func InitEngine() error {
	var err error
	conf := config.GetConfig()
	engine, err = xorm.NewEngine("mysql", conf.DBConfig.DbUser+
		":"+conf.DBConfig.DbPassword+"@tcp("+conf.DBConfig.DbHost+":"+conf.DBConfig.DbPort+")/"+conf.DBConfig.DbName+"?charset=utf8")
	if err != nil {
		err = errors.Wrap(err, "InitEngine1")
		return err
	}
	err = engine.Ping()
	if err != nil {
		err = errors.Wrap(err, "InitEngine2")
		return err
	}
	return nil
}

func GetEngine() *xorm.Engine {
	return engine
}

我们再创建一个sql，等会测试连接用：

DROP DATABASE IF EXISTS `test`;
CREATE DATABASE `test`;
USE `test`;
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users`
(
    `id`   int(11)     NOT NULL AUTO_INCREMENT COMMENT 'id',
    `name` varchar(40) NOT NULL COMMENT '名字',
    `age`  int         NOT NULL DEFAULT 0 COMMENT '年龄',
    PRIMARY KEY (`id`)
) ENGINE = InnoDB COMMENT 'users';

同样先添加配置：
config.json:

"redis_config": {
    "addr": "127.0.0.1:6379",
    "password": "",
    "db": 0
  }

config.go:

type RedisConfig struct {
	Addr     string `json:"addr"`
	Password string `json:"password"`
	DB       int    `json:"db"`
}

初始化redis：

func InitRedis() error {
	conf := config.GetConfig()
	client = redis.NewClient(&redis.Options{
		Addr:     conf.RedisConfig.Addr,
		Password: conf.RedisConfig.Password,
		DB:       conf.RedisConfig.DB,
	})

	pong, err := client.Ping().Result()
	if err != nil {
		err = errors.Wrap(err, "InitRedis")
		return err
	}
	logger.GetLogger().Info("Redis ping:", zap.String("ping", pong))
	return nil
}

err = db.InitEngine()
	if err != nil {
		fmt.Printf("Init DB failed. Error is %v", err)
		os.Exit(1)
	}

	err = redis.InitRedis()
	if err != nil {
		fmt.Printf("Init Redis failed. Error is %v", err)
		os.Exit(1)
	}

使用上面的sql，创建一个数据库叫做test，然后搭建redis，接着我们测试一下：

编译：

go build

运行：

awesomeframework --config=./config/config.json

看下日志打印：

2020-01-20T20:09:26.798+0800	info	Redis ping:	{"ping": "PONG"}
2020-01-20T20:09:26.798+0800	info	Init success.
