HarmonyOS Entry和Hsp中创建的单例失效？

Question

export class GlobalContext {
  private constructor() { }
  private static instance: GlobalContext;
  private _objects = new Map<string, Object>();

  public static getContext(): GlobalContext {
    if (!GlobalContext.instance) {
      GlobalContext.instance = new GlobalContext();
    }
    return GlobalContext.instance;
  }

  getObject(value: string): Object | undefined {
    return this._objects.get(value);
  }

  setObject(key: string, objectClass: Object): void {
    this._objects.set(key, objectClass);
  }
}

在Entry 中 存值 GlobalContext.getContext().setObject(“windowStage”, windowStage)

在动态共享包中取值 let windowStage = GlobalContext.getContext().getObject(“windowStage”) as window.WindowStage 取不到

排查发现 GlobalContext.getContext() 获取到的不是一个实例，单例失效了

如何解决？

Answer 1

目前windowStage只在entryAbility的onwindowStageCreate中获取到，然后需要用APPStorage把windowStage拿出来。示例如下：

onWindowStageCreate(windowStage: window.WindowStage): void {
  // Main window is created, set main page for this ability
  windowStage.loadContent('pages/Index', (err) => {
  if (err.code) {
   return;
}
});
AppStorage.setOrCreate('windowStage',windowStage);
}
