看样子你需要打电话
GetMessage或者
PeekMessage，这是奇怪的-这是不是说明文档中提到的钩子或
LowLevelKeyboardProc。我对API的这一部分了解不足，无法猜测原因。
我只是使用示例类：
import com.sun.jna.examples.win32.*;public class Callback { public static User32.HHOOK hHook; public static User32.LowLevelKeyboardProc lpfn; public static volatile boolean quit = false; public static void main(String[] args) throws Exception { W32API.HMODULE hMod = Kernel32.INSTANCE.GetModuleHandle(null); lpfn = new User32.LowLevelKeyboardProc() { public W32API.LRESULT callback(int nCode, W32API.WPARAM wParam, User32.KBDLLHOOKSTRUCT lParam) { System.out.println("here"); quit = true; return User32.INSTANCE.CallNextHookEx(hHook, nCode, wParam, lParam .getPointer()); } }; hHook = User32.INSTANCE.SetWindowsHookEx(User32.WH_KEYBOARD_LL, lpfn, hMod, 0); if (hHook == null) return; User32.MSG msg = new User32.MSG(); while (!quit) { User32.INSTANCE.PeekMessage(msg, null, 0, 0, 0); Thread.sleep(100); } if (User32.INSTANCE.UnhookWindowsHookEx(hHook)) System.out.println("Unhooked"); }}
