java中如何根據(jù)一個網(wǎng)址獲得該網(wǎng)頁的源代碼？

HttpURLConnection urlConnection = (HttpURLConnection) url

Java網(wǎng)站的源代碼怎么在本地運行

首先 java網(wǎng)站是基于jdk運行的。你得先裝jdk。去官網(wǎng)下載一個jdk安裝。然后你得編譯你的項目，打包到容器（tomcat,weblogic,jboss等）中運行即可。再提醒一下就是，看看你的源代碼有木有用到數(shù)據(jù)庫或者其他類型的服務(wù)。如果有的話，你得裝數(shù)據(jù)庫或服務(wù)，并且初始化數(shù)據(jù)。再啟動你的你的容器。

運行時可調(diào)用瀏覽器打開一個網(wǎng)頁，網(wǎng)頁地址在代碼中的java代碼怎么寫？

網(wǎng)頁地址在代碼中的java代碼寫法如下：

package com.test;

import java.lang.reflect.Method;

//實現(xiàn)打開瀏覽器并跳到指定網(wǎng)址的類

public class BareBonesBrowserLaunch {

public static void openURL(String url) {

try {

browse(url);

} catch (Exception e) {

}

}

private static void browse(String url) throws Exception {

//獲取操作系統(tǒng)的名字

String osName = System.getProperty("os.name", "");

if (osName.startsWith("Mac OS")) {

//蘋果的打開方式

Class fileMgr = Class.forName("com.apple.eio.FileManager");

Method openURL = fileMgr.getDeclaredMethod("openURL", new Class[] { String.class });

openURL.invoke(null, new Object[] { url });

} else if (osName.startsWith("Windows")) {

//windows的打開方式。

Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);

} else {

// Unix or Linux的打開方式

String[] browsers = { "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" };

String browser = null;

for (int count = 0; count browsers.length browser == null; count++)

//執(zhí)行代碼，在brower有值后跳出，

//這里是如果進(jìn)程創(chuàng)建成功了，==0是表示正常結(jié)束。

if (Runtime.getRuntime().exec(new String[] { "which", browsers[count] }).waitFor() == 0)

browser = browsers[count];

if (browser == null)

throw new Exception("Could not find web browser");

else

//這個值在上面已經(jīng)成功的得到了一個進(jìn)程。

Runtime.getRuntime().exec(new String[] { browser, url });

}

}

}

//主方法 測試類

public static void main(String[] args) {

String url = ""; ? ? ?

BareBonesBrowserLaunch.openURL(url);

}
