简而言之,我正在开发一个应用程序,我尝试在java.policy
文件中手动设置权限,但没有任何效果。它每次都会产生相同的异常..
java.lang.SecurityException: this KeyboardFocusManager is not installed in the current thread's context
at java.awt.KeyboardFocusManager.getGlobalFocusedWindow(KeyboardFocusManager.java:733)
at javaapplication1.Temp.go(Temp.java:26)
at javaapplication1.Temp.main(Temp.java:35)
无论如何,我可以通过编程或手动添加这一行,权限 java.awt.AWTPermission "replaceKeyboardFocusManager";
进入java.Policy
,我需要让这个东西工作,我有什么遗漏吗?
