最近做Go開(kāi)發(fā)的時(shí)候接觸到了一個(gè)新的orm第三方框架gorose，在使用的過(guò)程中，發(fā)現(xiàn)沒(méi)有類似beego進(jìn)行直接對(duì)struct結(jié)構(gòu)進(jìn)行操作的方法，有部分API是通過(guò)map進(jìn)行數(shù)據(jù)庫(kù)相關(guān)操作，那么就需要我們把struct轉(zhuǎn)化成map，下面是是我嘗試兩種不同struct轉(zhuǎn)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(xué)",City: "zhongguoguanzhou",Company: "sndifneinsifnienisn",Age: 23,Sex: "F",Proviece: "jianxi",Com: "廣州蘭博基尼",PostTo: "藍(lán)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(guò)struct轉(zhuǎn)json，json轉(zhuǎn)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(xué)",City: "zhongguoguanzhou",Company: "sndifneinsifnienisn",Age: 23,Sex: "F",Proviece: "jianxi",Com: "廣州蘭博基尼",PostTo: "藍(lán)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)) }

二、通過(guò)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(xué)",City: "zhongguoguanzhou",Company: "sndifneinsifnienisn",Age: 23,Sex: "F",Proviece: "jianxi",Com: "廣州蘭博基尼",PostTo: "藍(lán)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)) }
