当我从 eclipse 运行 中使用 Swing JDialog 但无法从 windows service(services.msc) 工作时，Swing JDialog 显示正常
Swing JDialog is showing fine when I run it from eclipse but not working from windows service(services.msc)
我有一个 java 应用程序，它在一定的时间间隔内 运行s 并显示一个弹出窗口（由 java swing 制作）。当我 运行 来自 eclipse 的应用程序时，它工作正常。在我使用 java -jar 命令创建了一个 jar 并 运行 它之后，它也工作正常。但是当我 运行 来自 windows service(services.msc) Popup window 的 jar 文件没有出现时，除了 popup 所有工作正常，例如记录数据获取等。
我没有找到任何解决方案，我已经应用了堆栈溢出中的所有解决方案，但问题仍然存在。

我相信你的问题不在Java。 AFAIK 服务 运行 在后台 - 无论用户是否登录。因此他们通常无法访问 GUI。
如果您的应用程序应 运行 在后台但在用户上下文中，也许您想将您的应用程序移动到自动启动程序文件夹，以便 Windows 将在用户登录时启动它。
