Java 实现全局（全操作系统）的鼠标和键盘监控，使用的是SWT Win32 Extension 项目，在以前若使用Java恐怕是很难实现的！

SWT Win32 Extension 让Java拥有了许多对操作系统底层操作的功能！

注：本程序需要SWT Win32 Extension支持?

以下两个例子是：

（一）鼠标Hook

import org.sf.feeling.swt.win32.extension.hook.Hook;import org.sf.feeling.swt.win32.extension.hook.data.HookData;import org.sf.feeling.swt.win32.extension.hook.data.MouseHookData;import org.sf.feeling.swt.win32.extension.hook.listener.HookEventListener;  public class HotMouse {  public static void main(String[] args) {  Hook.MOUSE.addListener(new HookEventListener() {   public void acceptHookData(HookData hookData) {    if (hookData != null) {      //System.out.println("Mouse Point X = " + ((MouseHookData)hookData).getPointX());      //System.err.println("Mouse Point Y =" + ((MouseHookData)hookData).getPointY());    	System.err.println(((MouseHookData)hookData).getPointX()+"," + ((MouseHookData)hookData).getPointY());    }    if (hookData.getWParam() == 513) {         System.out.println("left button pressed");// left button pressed    } else if (hookData.getWParam() == 514) {  System.out.println("left button released");// left button released    } else if (hookData.getWParam() == 516) {  System.out.println("right button pressed");// right button pressed    } else if (hookData.getWParam() == 517) {  System.out.println("right button");// right button    } else if (hookData.getWParam() == 519) {  System.out.println("middle button 519");// middle button    } else if (hookData.getWParam() == 520) {  System.out.println("middle button 520");// middle button    }   }  });  Hook.MOUSE.install(); } }

（二）键盘Hook

import org.sf.feeling.swt.win32.extension.hook.Hook;import org.sf.feeling.swt.win32.extension.hook.data.HookData;import org.sf.feeling.swt.win32.extension.hook.data.KeyboardHookData;import org.sf.feeling.swt.win32.extension.hook.listener.HookEventListener;  public class HotKey { public static void main(final String[] args) {  Hook.KEYBOARD.addListener(new HookEventListener(){//@Override  public void acceptHookData(HookData arg0) {   KeyboardHookData KHD = ((KeyboardHookData)arg0);   System.out.println(KHD.getWParam()+" - "+KHD.getTransitionState());  //Print code    if( KHD.getScanCode() == 29 && KHD.getTransitionState()){  //按下Ctrl執行動作    System.out.println("Hotting");   }else if( KHD.getScanCode() == 1 ){  //按下[ESC]結束    System.exit(0);   }  }});  Hook.KEYBOARD.install();  //註冊事件 }}

以上两个例子源于：这里要感谢！感谢！
