Java 作为具有交互式桌面支持和读取当前登录用户的 Windows 服务

Question

我有一个 java 程序，它的工作方式类似于使用 apache Common Deamon (prunsrv) 包装的 Windows 服务，但我有 2 个问题:
1. 该服务配置了交互式桌面，可以从应用程序中看到 Swing 对话框和尝试图标。但是 idalogs 和 try 图标没有出现。
2. 交互式桌面如何只与本地系统帐户一起工作，应用程序无法读取当前登录的用户，这个用户名是应用程序所必需的

然后我需要解决这两个问题，谢谢，我粘贴主类的代码

出于安全原因，默认情况下 Windows 不允许服务与桌面交互。您必须创建两个进程:一个用于唯一的服务部分(作为服务运行，没有任何交互)，另一个进程作为 Windows 应用程序标准运行。并在它们之间建立通信。
