最近工作中遇到一个需求,是要利用java打开指定浏览器,整理后发现有四种解决的方法,所以想着分享出来,下面这篇文章主要给大家介绍了java程序中指定某个浏览器打开的实现方法,,需要的朋友可以参考下。

本文主要介绍的是利用java程序打开指定某个的浏览器,文中分享了四种实现方法,感兴趣的朋友们下面来一起看看吧。

方法一:

package com.test;
 
import java.lang.reflect.Method;
 
//实现打开浏览器并跳到指定网址的类
public class BareBonesBrowserLaunch {
 public static void openURL(String url) { 
  try { 
   browse(url); 
  } catch (Exception e) { 
  } 
 } 
 
 private static void browse(String url) throws Exception { 
  //获取操作系统的名字 
  String osName = System.getProperty("os.name", ""); 
  if (osName.startsWith("Mac OS")) { 
   //苹果的打开方式 
   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的打开方式。 
   Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url); 
  } else { 
   // Unix or Linux的打开方式 
   String[] browsers = { "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" }; 
   String browser = null; 
   for (int count = 0; count < browsers.length && browser == null; count++) 
    //执行代码,在brower有值后跳出, 
    //这里是如果进程创建成功了,==0是表示正常结束。 
    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 
    //这个值在上面已经成功的得到了一个进程。 
    Runtime.getRuntime().exec(new String[] { browser, url }); 
  } 
 } 
}
 
//主方法 测试类
public static void main(String[] args) {
 // 这里填写你的网址
 String url = "xxx";   
 BareBonesBrowserLaunch.openURL(url); 
}

方法二:

使用默认浏览器打开:

 String site = "www.baidu.com";
 try {
  Desktop desktop = Desktop.getDesktop();
  if (desktop.isDesktopSupported() && desktop.isSupported(Desktop.Action.BROWSE)) {
   URI uri = new URI(site);
   desktop.browse(uri);
  }
 } catch (IOException ex) {
  System.out.println(ex);
 } catch (URISyntaxException ex) {
  System.out.println(ex);
 }

方法三:

通过获取环境变量的浏览器路径,然后启动浏览器

String firefox="C:\\Program Files\\Mozilla Firefox\\firefox.exe";
    Map map = System.getenv();
    for(Iterator itr = map.keySet().iterator();itr.hasNext();){
     String value = (String)map.get((String)itr.next());
     if (value.contains("firefox.exe")) {
      firefox=value;
      break;
    }
    } 
     Runtime.getRuntime().exec(new String[] {firefox, "www.baidu.com" });

方法四:

js方式:

<script type="text/javascript">
window.onload=function(){
var WSH = new ActiveXObject("Wscript.Shell"); 
  WSH.Run("chrome.exe www.baidu.com"); 
}
 
</script>
