HarmonyOS 是否有json转实体类的工具

可使用三方库，链接参考：https://ohpm.openharmony.cn/#/cn/detail/reflect-metadatahttps://www.npmjs.com/package/reflect-metadata/v/0.1.13

1、引入三方库：

ohpm install class-transformer
ohpm install reflect-metadata

2、代码示例：

import { Type, plainToClass } from 'class-transformer'
import "reflect-metadata"

const jsonString = '{"name": "John", "age": 30, "city": "New York"}';

class User {
  name: string = '';
  age: number = 0;
  city: string = '';

  getName() {
    return this.name
  }
}

const jsonObject: Object = JSON.parse(jsonString);
let instance = plainToClass(User, jsonObject)
console.log(instance.getName())
