Java如何屏蔽Windows按鍵？具體代碼如下：

import com.sun.jna.platform.win32.Kernel32;

import com.sun.jna.platform.win32.User32;

import com.sun.jna.platform.win32.WinDef.HMODULE;

import com.sun.jna.platform.win32.WinDef.LRESULT;

import com.sun.jna.platform.win32.WinDef.WPARAM;

import com.sun.jna.platform.win32.WinUser.HHOOK;

import com.sun.jna.platform.win32.WinUser.KBDLLHOOKSTRUCT;

import com.sun.jna.platform.win32.WinUser.LowLevelKeyboardProc;

import com.sun.jna.platform.win32.WinUser.MSG;

public class KeyHook {

private static HHOOK hhk;

private static LowLevelKeyboardProc keyboardHook;

private static User32 lib;

public static void blockWindowsKey() {

if (isWindows()) {

new Thread(new Runnable() {

@Override

public void run() {

lib = User32.INSTANCE;

HMODULE hMod = Kernel32.INSTANCE.GetModuleHandle(null);

keyboardHook = new LowLevelKeyboardProc() {

public LRESULT callback(int nCode, WPARAM wParam, KBDLLHOOKSTRUCT info) {

if (nCode >= 0) {

switch (info.vkCode) {

case 0x5B:

case 0x5C:

return new LRESULT(1);

default: //do nothing

}

}

return lib.CallNextHookEx(hhk, nCode, wParam, info.getPointer());

}

};

hhk = lib.SetWindowsHookEx(13, keyboardHook, hMod, 0);

int result;

MSG msg = new MSG();

while ((result = lib.GetMessage(msg, null, 0, 0)) != 0) {

if (result == -1) {

break;

} else {

lib.TranslateMessage(msg);

lib.DispatchMessage(msg);

}

}

lib.UnhookWindowsHookEx(hhk);

}

}).start();

}

}

public static void unblockWindowsKey() {

if (isWindows() && lib != null) {

lib.UnhookWindowsHookEx(hhk);

}

}

public static boolean isWindows() {

String os = System.getProperty("os.name").toLowerCase();

return (os.indexOf("win") >= 0);

}

}
