Go開發Struct轉換成map兩種方式比較

最近做Go開發的時候接觸到了一個新的orm第三方框架gorose，在使用的過程中，發現沒有類似beego進行直接對struct結構進行操作的方法，有部分API是通過map進行數據庫相關操作，那么就需要我們把struct轉化成map，下面是是我嘗試兩種不同struct轉換成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:   "廣州第十五中學",City:     "zhongguoguanzhou",Company:  "sndifneinsifnienisn",Age:      23,Sex:      "F",Proviece: "jianxi",Com:      "廣州蘭博基尼",PostTo:   "藍鯨XXXXXXXX",Buys:     "shensinfienisnfieni",Hos:      "zhonsndifneisnidnfie",}j, _ := json.Marshal(person)json.Unmarshal(j, &m)fmt.Println(m)fmt.Println(time.Now().Sub(t))
}

一、通過struct轉json，json轉成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:   "廣州第十五中學",City:     "zhongguoguanzhou",Company:  "sndifneinsifnienisn",Age:      23,Sex:      "F",Proviece: "jianxi",Com:      "廣州蘭博基尼",PostTo:   "藍鯨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:廣州蘭博基尼 Hos:zhonsndifneisnidnfie Name:zhaondifnei Company:sndifneinsifnienisn Buys:shensinfienisnfieni Age:23 PostTo:藍鯨XXXXXXXX Address:大沙地 School:廣州第十五中學 City:zhongguoguanzhou Sex:F Id:98439 Email:dashdisnin@126.com]

二、通過反射形式生成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:   "廣州第十五中學",City:     "zhongguoguanzhou",Company:  "sndifneinsifnienisn",Age:      23,Sex:      "F",Proviece: "jianxi",Com:      "廣州蘭博基尼",PostTo:   "藍鯨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:廣州蘭博基尼 Id:98439 School:廣州第十五中學 Address:大沙地 Age:23 PostTo:藍鯨XXXXXXXX Hos:zhonsndifneisnidnfie Email:dashdisnin@126.com Company:sndifneinsifnienisn]

　　結論

通過比較可以看出，通過反射的形式轉換基本上是通過json形式轉換的兩倍。
