HarmonyOS 鸿蒙Next 在自定义page页面添加类装饰器无效

// 权限外部组件
[@Component](/user/Component)
struct PermissionWrapper {
  [@State](/user/State) permissionKey: string = "NONE"
  [@BuilderParam](/user/BuilderParam) closure: () => void
  [@State](/user/State) permissionInfo: PermissionInfo = new PermissionInfo()

  aboutToAppear(): void {
    this.permissionInfo = PermissionModule.getUserPermission(this.permissionKey)
  }
  build() {
    Column() {
      this.closure()
    }
    // 做权限相关处理
    .visibility(this.permissionInfo.visibility)
    .onTouch(() => {
      // 事件拦截
    })
  }
}
// 组件内做一层包裹
[@Component](/user/Component)
struct HelloPage {
  [@State](/user/State) message: string = "Hello World"
  build() {
    Column() {
      // 非侵入式实现
      PermissionWrapper({permissionKey: PermissionModule.PERMISSION_1}) {
        Text(${this.message})
        .id('text')
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .alignRules({
            center: { anchor: 'container', align: VerticalAlign.Center },
            middle: { anchor: 'container', align: HorizontalAlign.Center }
          })
      }
    }
    .height('100%')
    .width('100%')
  }
}

上述方式可以集中对权限逻辑的处理，可以自行选择权限传入的形式。
