Go开发Struct转换成map两种方式比较

最近做Go开发的时候接触到了一个新的orm第三方框架gorose，在使用的过程中，发现没有类似beego进行直接对struct结构进行操作的方法，有部分API是通过map进行数据库相关操作，那么就需要我们把struct转化成map，下面是是我尝试两种不同struct转换成map的方法

mport ("encoding/json""fmt""reflect""time"
)type Persion struct {Id       intName     stringAddress  stringEmail    stringSchool   stringCity     stringCompany  stringAge      intSex      stringProviece stringCom      stringPostTo   stringBuys     stringHos      string
}func main() {StructToMapViaJson()//StructToMapViaReflect()
}func StructToMapViaJson() {m := make(map[string]interface{})t := time.Now()person := Persion{Id:       98439,Name:     "zhaondifnei",Address:  "大沙地",Email:    "dashdisnin@126.com",School:   "广州第十五中学",City:     "zhongguoguanzhou",Company:  "sndifneinsifnienisn",Age:      23,Sex:      "F",Proviece: "jianxi",Com:      "广州兰博基尼",PostTo:   "蓝鲸XXXXXXXX",Buys:     "shensinfienisnfieni",Hos:      "zhonsndifneisnidnfie",}j, _ := json.Marshal(person)json.Unmarshal(j, &m)fmt.Println(m)fmt.Println(time.Now().Sub(t))
}

一、通过struct转json，json转成map

func StructToMapViaJson() {m := make(map[string]interface{})t := time.Now()person := Persion{Id:       98439,Name:     "zhaondifnei",Address:  "大沙地",Email:    "dashdisnin@126.com",School:   "广州第十五中学",City:     "zhongguoguanzhou",Company:  "sndifneinsifnienisn",Age:      23,Sex:      "F",Proviece: "jianxi",Com:      "广州兰博基尼",PostTo:   "蓝鲸XXXXXXXX",Buys:     "shensinfienisnfieni",Hos:      "zhonsndifneisnidnfie",}j, _ := json.Marshal(person)json.Unmarshal(j, &m)fmt.Println(m)fmt.Printf("duration:%d", time.Now().Sub(t))
}
output:
map[Proviece:jianxi Com:广州兰博基尼 Hos:zhonsndifneisnidnfie Name:zhaondifnei Company:sndifneinsifnienisn Buys:shensinfienisnfieni Age:23 PostTo:蓝鲸XXXXXXXX Address:大沙地 School:广州第十五中学 City:zhongguoguanzhou Sex:F Id:98439 Email:dashdisnin@126.com]
duration:250467

　　

二、通过反射形式生成map

func StructToMapViaReflect() {m := make(map[string]interface{})t := time.Now()person := Persion{Id:       98439,Name:     "zhaondifnei",Address:  "大沙地",Email:    "dashdisnin@126.com",School:   "广州第十五中学",City:     "zhongguoguanzhou",Company:  "sndifneinsifnienisn",Age:      23,Sex:      "F",Proviece: "jianxi",Com:      "广州兰博基尼",PostTo:   "蓝鲸XXXXXXXX",Buys:     "shensinfienisnfieni",Hos:      "zhonsndifneisnidnfie",}elem := reflect.ValueOf(&person).Elem()relType := elem.Type()for i := 0; i < relType.NumField(); i++ {m[relType.Field(i).Name] = elem.Field(i).Interface()}fmt.Println(m)fmt.Printf("duration:%d", time.Now().Sub(t))
}
output:
map[Buys:shensinfienisnfieni Name:zhaondifnei City:zhongguoguanzhou Sex:F Proviece:jianxi Com:广州兰博基尼 Id:98439 School:广州第十五中学 Address:大沙地 Age:23 PostTo:蓝鲸XXXXXXXX Hos:zhonsndifneisnidnfie Email:dashdisnin@126.com Company:sndifneinsifnienisn]
duration:104239

　　结论

通过比较可以看出，通过反射的形式转换基本上是通过json形式转换的两倍。
