HarmonyOS 范型列表转化问题

泛型数据，参考示例：

@Entry
@Component
struct GenericsT {
  build() {
    Column() {
      Button('测试').onClick((event: ClickEvent) => {
        this.test()
      })
    }
  }

  test() {
    let obj: ESObject = { 'sum': 'value', 'bbb': 'ccc' };
    let reClass: ResponseJson<TestMap> = new ResponseJsonClass(true, 'dsa', 'dgger', obj);
    console.log('111: ' + JSON.stringify(reClass))
  }
}

export interface ResponseJson<R> {
  success: boolean
  errorCode: string
  message?: string
  data: R | null
}

export class ResponseJsonClass<R> implements ResponseJson<R> {
  success: boolean = false
  errorCode: string = ''
  message?: string
  data: R | null = null
  constructor(success: boolean, errorCode: string, message: string, data: R | null) {
    this.success = success;
    this.errorCode = errorCode;
    this.message = message;
    this.data = data;
  }
}

// 其中泛型R可以转换成其他的类，比如以下类
export class TestMap {
  message: string;

  constructor(msg: string) {
    this.message = msg;
  }
}
