Java作為Windows服務，具有交互式桌面支持和已讀當前用戶

Question

我有一個Java程序，其工作方式類似於用apache Common Deamon（prunsrv）包裝的Windows服務，但我有兩個問題：
1.使用交互式桌面對其服務進行配置的服務，可以從應用程序中查看擺動對話框和嘗試圖標。 但是idalogs and try圖標沒有出現。
2.交互式桌面如何僅與本地系統帳戶一起使用，應用程序無法讀取當前登錄的用戶，此用戶名是應用程序所必需的

然后我需要解決這2個問題，謝謝，我從主類粘貼了代碼

Answer 1

默認情況下，出於安全原因，Windows不允許服務與桌面進行交互。 您必須創建兩個進程：一個用於唯一的服務部分（作為服務運行，沒有任何交互），另一個用於Windows應用程序標准運行。 並在他們之間建立溝通。

Answer 2

從我的問題中可以理解，第二個問題可能是代碼覆蓋了從System.properties調用中接收到的用戶名String（帶有靜態代碼）引起的，如下所示：

 username = System.getProperty("user.name"); username = "Javier"; //remove me 

至於您的其他問題，我將查看您使用的包裝器。 我確定有某種API。 （我還沒有玩過服務……）。
