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！

以下两个例子是：

(一)鼠标Hook

importorg.sf.feeling.swt.win32.extension.hook.Hook;

importorg.sf.feeling.swt.win32.extension.hook.data.HookData;

importorg.sf.feeling.swt.win32.extension.hook.data.MouseHookData;

importorg.sf.feeling.swt.win32.extension.hook.listener.HookEventListener;

publicclassHotMouse {

publicstaticvoidmain(String[] args) {

Hook.MOUSE.addListener(newHookEventListener() {

publicvoidacceptHookData(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

} elseif(hookData.getWParam() ==514) {  System.out.println("left button released");// left button released

} elseif(hookData.getWParam() ==516) {  System.out.println("right button pressed");// right button pressed

} elseif(hookData.getWParam() ==517) {  System.out.println("right button");// right button

} elseif(hookData.getWParam() ==519) {  System.out.println("middle button 519");// middle button

} elseif(hookData.getWParam() ==520) {  System.out.println("middle button 520");// middle button

}

}

});

Hook.MOUSE.install();

}

}

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

importorg.sf.feeling.swt.win32.extension.hook.Hook;

importorg.sf.feeling.swt.win32.extension.hook.data.HookData;

importorg.sf.feeling.swt.win32.extension.hook.data.KeyboardHookData;

importorg.sf.feeling.swt.win32.extension.hook.listener.HookEventListener;

publicclassHotKey {

publicstaticvoidmain(finalString[] args) {

Hook.KEYBOARD.addListener(newHookEventListener(){//@Override

publicvoidacceptHookData(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");

}elseif( KHD.getScanCode() ==1){//按下[ESC]結束

System.exit(0);

}

}});

Hook.KEYBOARD.install();  //註冊事件

}

}

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

}

}
