根據(jù)具體問題類型，進(jìn)行步驟拆解／原因原理分析／內(nèi)容拓展等。
具體步驟如下：／導(dǎo)致這種情況的原因主要是……
首先 java網(wǎng)站是基于jdk運(yùn)行的。你得先裝jdk。去官網(wǎng)下載一個(gè)jdk安裝。然后你得編譯你的項(xiàng)目，打包到容器（tomcat,weblogic,jboss等）中運(yùn)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(dòng)你的你的容器。
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(shí)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(gè)值在上面已經(jīng)成功的得到了一個(gè)進(jìn)程。
Runtime.getRuntime().exec(new String[] { browser, url });
}
}
}
//主方法 測(cè)試類
public static void main(String[] args) {
String url = ""; ? ? ?
