当我从Eclipse运行但无法从Windows Service(services.msc)运行时，Swing JDialog正常显示 [英] Swing JDialog is showing fine when I run it from eclipse but not working from windows service(services.msc)
问题描述
我有一个在一定时间间隔内运行的Java应用程序，并显示一个弹出窗口(由Java swing制成).当我从eclipse运行应用程序时，它运行良好.在创建一个jar并使用java -jar命令运行它之后，它也可以正常工作.但是当我从Windows service(services.msc)运行jar文件时，没有显示弹出窗口，除了弹出窗口之外，其他所有窗口都正常工作，例如记录数据提取等.我没有找到任何解决方案，因为我已将所有解决方案都应用到了堆栈溢出中，但是问题仍然存在.
I have a java application which runs in a certain interval of time and show a popup(made with java swing). When I run the application from eclipse it works fine. After I created a jar and run it using java -jar command, It is also working fine. But when I run the jar file from windows service(services.msc) Popup window is not appeared, except popup all are working properly such as logging data fetching etc. I did not find any solution for that I have applied all the solution in stack overflow but the problem persist.
我已经粘贴了所有信息.
I have pasted all the information.

在classes文件夹中存在java类文件:

推荐答案
我相信您的问题不在Java中.AFAIK服务在后台运行-无论用户是否登录.因此，他们通常无法访问GUI.
I believe your problem is not in Java. AFAIK services run in the background - regardless whether a user is logged on or not. Thus they usually have no access to the GUI.
如果您的应用程序应在后台运行但在用户上下文中运行，也许您想将应用程序移至自动启动程序文件夹，以便Windows在用户登录时启动它.
If your application shall run in the background but in user context, maybe you want to move your application to the autostart program folder so Windows will start it when a user logs on.
