golang 是Google开发的一种静态强类型、编译型、并发型,并具有垃圾回收功能的编程语言,其语法与 C语言相近,但并不包括如枚举、异常处理、继承、泛型、断言、虚函数等功能。
mport ( "encoding/json" "fmt" "reflect" "time" ) type Persion struct { Id int Name string Address string Email string School string City string Company string Age int Sex string Proviece string Com string PostTo string Buys string Hos 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]
