我只知道它屬于org.eclipse.pde.ui的擴展點org.eclipse.ui.perspectives，看來要好好研究一下這部分的代碼，才能解決隱藏Perspective，實現權限管理。
參考了別人的代碼:
看了看eclipse的源代碼，終于知道怎么關閉了:
IWorkbench w=PlatformUI.getWorkbench();
IPerspectiveRegistry pr=w.getPerspectiveRegistry() ;
IPerspectiveDescriptor persdes=pr.findPerspectiveWithId("perspectiveID");
WorkbenchPage p=(WorkbenchPage)w.getActiveWorkbenchWindow().getActivePage();
Perspective persp = p.getActivePerspective();
p.closePerspective(persdes,false,false);
try {
w.showPerspective("nextperspectiveID", w.getActiveWorkbenchWindow());
} catch (WorkbenchException e) {
e.printStackTrace();
}
關閉當前perspective，并打開一個新的perspective:
IWorkbench w=PlatformUI.getWorkbench();
ActionFactory.IWorkbenchAction closePerspectiveAction
= ActionFactory.CLOSE_PERSPECTIVE.create(w.getActiveWorkbenchWindow());
closePerspectiveAction.run();
try {
PlatformUI.getWorkbench().showPerspective("com.ibm.demo.saic.ui.views.NextPerspective", w.getActiveWorkbenchWindow());
} catch (WorkbenchException e) {
e.printStackTrace();
}
