Java swing 实现对电脑屏幕的鼠标移动事件和键盘输入的监控

通俗点就是一个程序,能够对电脑屏幕上鼠标移动的事件和键盘输入的ascii值进行监控,本人一开始写了一个,但是只是在我的程序cs端内的范围有效,如何实现对整个屏幕的监控,有大神知道吗?

用键盘钩子实现，java不方便写原生代码，可以用c++写好，记录下来，传给java的程序。

用JAVA确实不方便，用C/C++，VB的比较多，关于HOOK及监控，可以参考以下内容，希望对你有帮助

java有两种方案（我自己做过的）
1.jna，代码结构类似：

    private final LowLevelKeyboardProc keyboardHook = new LowLevelKeyboardProc() {

        // http://msdn.microsoft.com/en-us/library/windows/desktop/ms644985(v=vs.85).aspx
        public LRESULT callback(int nCode, WPARAM wParam, KBDLLHOOKSTRUCT lParam) {
            int w = wParam.intValue();
            // 按下alt键时w=.WM_SYSKEYDOWN; 按下其他大部分键时w=WinUser.WM_KEYDOWN
            if (w == WinUser.WM_KEYDOWN || w == WinUser.WM_SYSKEYDOWN) {
                for (KeyboardListener l : keyListeners) {
                    l.keyPressed(lParam.vkCode);
                }
            } else if (w == WinUser.WM_KEYUP || w == WinUser.WM_SYSKEYUP) {
                for (KeyboardListener l : keyListeners) {
                    l.keyReleased(lParam.vkCode);
                }
            }

            return User32.INSTANCE.CallNextHookEx(keyboardHHK, nCode, wParam, lParam.getPointer());
        }
    };

    private final LowLevelMouseProc mouseHook = new LowLevelMouseProc() {

        // http://msdn.microsoft.com/en-us/library/windows/desktop/ms644986(v=vs.85).aspx
        public LRESULT callback(int nCode, WPARAM wParam, MouseHookStructure lParam) {
            int x = lParam.pt.x;
            int y = lParam.pt.y;
            switch (wParam.intValue()) {
                case WM_MOUSEMOVE :
                    for (MouseListener l : mouseListeners) {
                        l.mouseMoved(x, y);
                    }
                    break;
                case WM_LBUTTONDOWN :
                    for (MouseListener l : mouseListeners) {
                        l.leftButtonDown(x, y);
                    }
                    break;
                case WM_LBUTTONUP :
                    for (MouseListener l : mouseListeners) {
                        l.leftButtonUp(x, y);
                    }
                    break;
                case WM_RBUTTONUP :
                    for (MouseListener l : mouseListeners) {
                        l.rightButtonUp(x, y);
                    }
                    break;
                case WM_RBUTTONDOWN :
                    for (MouseListener l : mouseListeners) {
                        l.rightButtonDown(x, y);
                    }
                    break;
                case WM_MOUSEWHEEL :
                    for (MouseListener l : mouseListeners) {
                        l.mouseWheelMoved();
                    }
                    break;
            }
            return User32.INSTANCE.CallNextHookEx(mouseHHK, nCode, wParam, lParam.getPointer());
        }
    };

用的其实就是hook+回调函数

原理同上
看官方的sample就行了
