Golang 通过结构体实现字典按值排序

package main
 
import (
	"fmt"
	"sort"
)
 
func main() {
	mapInfo := map[string]int32{
		"roy":18,
		"kitty":16,
		"hugo":21,
		"tina":35,
		"jason":23,
	}
 
	type peroson struct {
		Name string
		Age int32
	}
 
	var lstPerson []peroson
	for k, v := range mapInfo {
		lstPerson = append(lstPerson, peroson {k, v})
	}
 
	sort.Slice(lstPerson, func(i, j int) bool {
		return lstPerson[i].Age > lstPerson[j].Age  // 降序
		// return lstPerson[i].Age < lstPerson[j].Age  // 升序
	})
 
	fmt.Println(lstPerson)
}
