我正在Kotlin编写一个SSM项目,只要我尝试用一​​个类(一个服务实现)注释,就会发生这种情况@Service.

1. 尝试用Java代码编写这个实现类,它工作得很好.
2. 试图只保留必要的重要方法.
3. open 已添加.
4. context:component-scan 已配置.

如TypeScript中所述，是否具有InputEvent的类型定义？，我试图用@types/dom-inputevent，以获得InputEvent我的角7项目。但error TS2304: Cannot find name 'InputEvent'无论何时使用，它都会显示出来。

是否需要在Angular项目中“注册”它还是一个bug？

如果一个修复程序不可用，我只想要一个方便的方式来达到同样的结果event.data在InputEvent。

谢谢！

如何在 UWP 中的弹出窗口周围添加阴影？

我尝试在 UWP 社区工具包中使用 DropShadowPanel 来包装弹出窗口，但它没有与弹出窗口一起显示。我怎样才能实现它，以便阴影随着弹出窗口显示和消失？谢谢！
