Java作为Windows服务，具有交互式桌面支持和阅读当前记录的用户 [英] Java as windows service with interactive desktop support and read curren logged user
本文介绍了Java作为Windows服务，具有交互式桌面支持和阅读当前记录的用户的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个Java程序，其工作方式类似于用apache Common Deamon（prunsrv）包装的Windows服务，但是我有2个问题：
1.该服务的配置使用Interactive桌面可以查看摆动对话框并从应用程序尝试图标。但是idalogs and try图标不会出现。
2.交互式桌面如何仅与本地系统帐户一起使用，应用程序无法读取当前登录的用户，该用户名是应用程序所必需的
I have a java program that works like a windows service wrapped with apache Common Deamon (prunsrv) but i have 2 problems:
1. The service its configured with Interactive desktop to can see the swing dialogs and try icon from application. But the idalogs and try icon doesn´t appears.
2. How the interactive desktop only works with Local System Account the application can´t read the current logged user, this username its necessary for application
然后我需要解决这2个问题，谢谢，我粘贴了主类的代码
Then i need to resolve this 2 issues, thanks, i paste the code from main class

推荐答案
默认情况下，出于安全原因，Windows不允许服务与桌面进行交互。
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），另一个用于Windows应用程序标准运行。
并在它们之间建立通信。
By default Windows not allow to a service to interact with Desktop for security reason. you must create two process : one for the only service part (run as service, without any interacting), and another process run as Windows application standard. and create a communication between them.
