想用反射做一个map数组转结构体数组的方法，代码如下，不知道怎么把反射生成的结构体加进数组里，求大佬帮忙

``` package main import ( "errors" "fmt" "reflect" "strings" ) type User struct { Id int Name string Sex string } var users []*User func main() { mList := []map[string]interface{}{ {"Id": 213, "Name": "zhaoliu", "Sex": "男"}, {"Id": 56, "Name": "zhangsan", "Sex": "男"}, {"Id": 7, "Name": "lisi", "Sex": "女"}, {"Id": 978, "Name": "wangwu", "Sex": "男"}, } mapToStruct(mList, &users) fmt.Printf("users: %+v\n", users[0]) } func mapToStruct(mList []map[string]interface{}, model interface{}) (err error) { val := reflect.Indirect(reflect.ValueOf(model)) typ := val.Type() for _, r := range mList { mVal := reflect.Indirect(reflect.New(typ.Elem().Elem())).Addr() for key, val := range r { err = setField(mVal.Interface(), key, val) if err != nil { return err } } v, ok := mVal.Interface().(*User) if ok { users = append(users, v) } } return err } //用map的值替换结构的值 func setField(obj interface{}, name string, value interface{}) error { // 将首字母转换为大写 sl := strings.Split(name, "") sl[0] = strings.ToUpper(sl[0]) name = strings.Join(sl, "") structValue := reflect.ValueOf(obj).Elem() //结构体属性值 //fmt.Printf("structValue: %+v\n", structValue) structFieldValue := structValue.FieldByName(name) //结构体单个属性值 //fmt.Printf("structFieldValue: %+v\n", structFieldValue) if !structFieldValue.IsValid() { return fmt.Errorf("No such field: %s in obj", name) } if !structFieldValue.CanSet() { return fmt.Errorf("Cannot set %s field value", name) } structFieldType := structFieldValue.Type() //结构体的类型 val := reflect.ValueOf(value) //map值的反射值 if structFieldType != val.Type() { return errors.New("type is err") } structFieldValue.Set(val) return nil } ```

emmmm...你这样还要interface{}干嘛，你不能在方法里面调结构体呀，我这做的是一个组件，要支持任意类型的结构体。

好吧，我的理解错了。
