如何使用java打开默认的webbrowser

Question

有人可以指出我正确的方向如何打开默认的Web浏览器并将页面设置为"www.example.com"谢谢

Answer 1

java.awt.Desktop 是你正在寻找的课程.

import java.awt.Desktop;
import java.net.URI;

// ...

if (Desktop.isDesktopSupported() && Desktop.getDesktop().isSupported(Desktop.Action.BROWSE)) {
    Desktop.getDesktop().browse(new URI("http://www.example.com"));
}

Answer 2

这是我的代码.它将在默认浏览器(跨平台解决方案)中打开给定URL.

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

public class Browser {
    public static void main(String[] args) {
        String url = "http://www.google.com";

        if(Desktop.isDesktopSupported()){
            Desktop desktop = Desktop.getDesktop();
            try {
                desktop.browse(new URI(url));
            } catch (IOException | URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }else{
            Runtime runtime = Runtime.getRuntime();
            try {
                runtime.exec("xdg-open " + url);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

Answer 3

对我来说,使用Desktop.isDesktopSupported()的解决方案不起作用(Windows 7和ubuntu).请尝试从java代码打开浏览器:

视窗:

Runtime rt = Runtime.getRuntime();
String url = "http://stackoverflow.com";
rt.exec("rundll32 url.dll,FileProtocolHandler " + url);

苹果电脑

Runtime rt = Runtime.getRuntime();
String url = "http://stackoverflow.com";
rt.exec("open " + url);

Linux的:

Runtime rt = Runtime.getRuntime();
String url = "http://stackoverflow.com";
String[] browsers = { "epiphany", "firefox", "mozilla", "konqueror",
                                 "netscape", "opera", "links", "lynx" };

StringBuffer cmd = new StringBuffer();
for (int i = 0; i < browsers.length; i++)
    if(i == 0)
        cmd.append(String.format(    "%s \"%s\"", browsers[i], url);
    else
        cmd.append(String.format(" || %s \"%s\"", browsers[i], url); 
    // If the first didn't work, try the next browser and so on

rt.exec(new String[] { "sh", "-c", cmd.toString() });

如果要使用多平台应用程序,则需要添加操作系统检查(例如):

String os = System.getProperty("os.name").toLowerCase();

视窗:

os.indexOf("win") >= 0

苹果电脑:

os.indexOf("mac") >= 0

Linux的:

os.indexOf("nix") >=0 || os.indexOf("nux") >=0

Answer 4

希望你不介意，但我从上面拼凑了所有有用的东西，并提出了一个完整的课程以供测试......

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

public class MultiBrowPop {

    public static void main(String[] args) {
        OUT("\nWelcome to Multi Brow Pop.\nThis aims to popup a browsers in multiple operating systems.\nGood luck!\n");

        String url = "http://www.birdfolk.co.uk/cricmob";
        OUT("We're going to this page: "+ url);

        String myOS = System.getProperty("os.name").toLowerCase();
        OUT("(Your operating system is: "+ myOS +")\n");

        try {
            if(Desktop.isDesktopSupported()) { // Probably Windows
                OUT(" -- Going with Desktop.browse ...");
                Desktop desktop = Desktop.getDesktop();
                desktop.browse(new URI(url));
            } else { // Definitely Non-windows
                Runtime runtime = Runtime.getRuntime();
                if(myOS.contains("mac")) { // Apples
                    OUT(" -- Going on Apple with 'open'...");
                    runtime.exec("open " + url);
                } 
                else if(myOS.contains("nix") || myOS.contains("nux")) { // Linux flavours 
                    OUT(" -- Going on Linux with 'xdg-open'...");
                    runtime.exec("xdg-open " + url);
                }
                else 
                    OUT("I was unable/unwilling to launch a browser in your OS :( #SadFace");
            }
            OUT("\nThings have finished.\nI hope you're OK.");
        }
        catch(IOException | URISyntaxException eek) {
            OUT("**Stuff wrongly: "+ eek.getMessage());
        }
    }

    private static void OUT(String str) {
        System.out.println(str);
    }
}

Answer 5

您还可以使用Runtime创建跨平台解决方案:

import java.awt.Desktop;
import java.net.URI;

public class App {

    public static void main(String[] args) throws Exception {
        String url = "http://stackoverflow.com";

        if (Desktop.isDesktopSupported()) {
            // Windows
            Desktop.getDesktop().browse(new URI(url));
        } else {
            // Ubuntu
            Runtime runtime = Runtime.getRuntime();
            runtime.exec("/usr/bin/firefox -new-window " + url);
        }
    }
}

Answer 6

非常简单，只需编写以下代码：

String s = "http://www.google.com";
Desktop desktop = Desktop.getDesktop();
desktop.browse(URI.create(s));

或者，如果您不想加载 URL，则只需将您的浏览器名称写入字符串值，例如，

String s = "chrome";
Desktop desktop = Desktop.getDesktop();
desktop.browse(URI.create(s));

执行程序后，它会自动打开浏览器并显示空 URL

Answer 7

如Tim Cooper提供的答案中所述,java.awt.Desktop自Java版本6(1.6)以来已提供此功能,但有以下警告:

使用isDesktopSupported()方法确定Desktop API是否可用.在Solaris操作系统和Linux平台上,此API依赖于Gnome库.如果这些库不可用,则此方法将返回false.

对于不支持或提供的平台,请java.awt.Desktop查看BrowserLauncher2项目.它是由Eric Albert最初编写和发布的BrowserLauncher类派生并稍微更新的.我在一个多平台Java应用程序中成功使用了原始的BrowserLauncher类,该应用程序在21世纪初期通过Web浏览器界面在本地运行.

请注意,BrowserLauncher2是根据GNU宽通用公共许可证获得许可的.如果该许可证是不可接受的,请查找原始BrowserLauncher的副本,该副本具有非常自由的许可证:

BrowserLauncher2以外的项目可能还更新了原始的BrowserLauncher,以便考虑自2001年以来浏览器和默认系统安全设置的变化.
