利用java實現(xiàn)一個簡單的遠程監(jiān)控程序

1、利用java實現(xiàn)一個簡單的遠程監(jiān)控程序一般的遠程監(jiān)控軟件都是用c或者C+等語言開發(fā)的，而使用java如何來實現(xiàn)相同的功能呢。首先我們先介紹一下一個簡單的遠程監(jiān)控程序的實現(xiàn)原理。功能一，遠程屏幕監(jiān)視必須要有監(jiān)控端與被監(jiān)控端，而且程序保持啟動。被監(jiān)控端獲取本機的屏幕截屏發(fā)圖給監(jiān)控端。監(jiān)控端在本地窗口中顯示被監(jiān)控端發(fā)送過來的圖像。(2)(3)步驟重復(fù)執(zhí)行，這時在監(jiān)控端即可實時監(jiān)視到被監(jiān)控端的桌面操作了。功能二，遠程控制必須要有監(jiān)控端與被監(jiān)控端，而且程序保持啟動。在監(jiān)控端監(jiān)視窗體上執(zhí)行鼠標(biāo)點擊事件。記錄步驟(2)中的鼠標(biāo)點擊的坐標(biāo)，及鍵值發(fā)送到被監(jiān)控端。被監(jiān)控接受鼠標(biāo)坐標(biāo)，及鍵值，然后再本地屏幕上模擬

2、同樣的點擊動作。0K,現(xiàn)在看下具體的java與語言是如何實現(xiàn)上述功能的。使用java語言要實現(xiàn)截屏的功能就要依靠java類庫中的一個有趣的類java.awt.Robot類【俗稱Java機器人】了功能一，遠程屏幕監(jiān)視/客戶端抓取屏幕快照GuiCamera.javaJava代碼旦BufferedImagescreenshot=2(newRobot().createScreenCapture(,newRectangle(O,0,(int)size.getWidth(),4(int)size.getHeight();/客戶端發(fā)送快照SendThread.javaJava代碼至image=gc.snap

3、Shot();/保存為臨時文件Filefile=newFile(temp.png);FileOutputStreamfileout=newFileOutputStream(file);ImageIO.write(image,png,fileout);fileout.close();/讀取圖像FileInputStreamfileIn=newFileInputStream(file);intlen=(int)file.length();/建立字節(jié)數(shù)組bytebuf=newbytelen;fileIn.read(buf,0,len);/發(fā)送out.write(buf,0,len);out.flus

4、h();/間隔500毫秒6,8101213141161,18120212223242Thread.sleep(500);61Objectoptions=/監(jiān)控端接受圖像，Snap.javaJava代碼審publicvoidrun()while(flag)bytebuf=newbyte102400;tryimgStream=newBufferedInputStream(socket.getInputStream();imgStream.read(buf);ImageIconicon=newImageIcon(Toolkit.getDefaultToolkit().createImage(buf)

6、tem.out.println(服務(wù)器停止)；53功能二，遠程控制監(jiān)控端記錄鼠標(biāo)操作Snap.javaJava代碼54內(nèi)部類，主要功能監(jiān)聽鼠標(biāo)事件。記錄坐標(biāo)。5,classkeyAdapetextendsKeyAdapter57鍵盤監(jiān)聽適配器5publicvoidkeyTyped(KeyEvente)59if(e.getKeyChar()=27)按ESC鍵626364666768697071727,747767778798081828,確定,取消;intn=JOptionPane.showOptionDialog(null,是否退出程序?,遠程監(jiān)控系統(tǒng),JOptionPane.OK_CANCE

8、ente)if(e.BUTTON1=MouseEvent.BUTTON1)System.out.println(你按了鼠標(biāo)左鍵);intx=e.getX();inty=e.getY();if(tempSocket!=null)newCommandMsg(3,tempSocket,x,y).start();48586888990919293949,9699899100101102103監(jiān)控端發(fā)送坐標(biāo)Snap.javaJava代碼104publicvoidrun()105out.println(eventType+,+x+,+y);10out.flush();107客戶端獲取鼠標(biāo)坐標(biāo)后，在本機相同
