如何为NetBeans Java的jxbrowser添加许可证密钥？

问题描述

我正在尝试在Java应用程序中添加jxbrowser，但是由于无法显示我的许可证，因此无法运行我的应用程序。我从网站获得了免费许可证，在下面的代码中无法在此处显示许可证密钥，但是我想问一下我该如何配置和设置许可证密钥，因为我不断收到错误消息。您在下面参考。我想知道我是否正确设置了许可证。如果您看到下面的内容，我将许可证密钥替换为所有的“＃”，因为如果有人窃取它，我不能让人们看到它。让我知道如何解决我的问题。

public class locate extends javax.swing.JFrame {
    
    /**
     * Creates new form locate
     */
    public locate() {
        initComponents();
        open_site();
    }

    Browser browser;
    BrowserView view;
    private void open_site(){
        Engine engine = Engine.newInstance(
        EngineOptions.newBuilder(HARDWARE_ACCELERATED)
    .licenseKey("##############################################################")
                .build());
        System.setProperty("jxbrowser.license.key","###########################################################");
        //BrowserUtil;
        browser = new Browser();
        view = new BrowserView(browser);
        GoogleMapsPanel.add(view,BorderLayout.CENTER);
        browser.addTitleListener((TitleEvent evt) -> {
            setTitle(evt.getTitle());
        });
        
        browser.addConsoleListener((ConsoleEvent evt) -> {
            System.out.println("LOG: " + evt.getMessage());
        });
                
        browser.addLoadListener(new LoadAdapter() {
            @Override
            public void onFinishLoadingFrame(FinishLoadingEvent evt){
                evt.getBrowser().setZoomLevel(-2);
            }
        });
        
        browser.loadURL("/Users/jacksonseow/NetBeansProjects/PleaseWork/src/pleasework/googlemaps.html");
                
                
    }

}

错误：

解决方法

从给定的源代码中，我看到您在单个Java应用程序中混合了JxBrowser 7和6。以下代码属于7：

Engine engine = Engine.newInstance(
        EngineOptions.newBuilder(HARDWARE_ACCELERATED)
                .licenseKey("###############")
                .build());

以下几行属于JxBrowser 6：

browser = new Browser();
view = new BrowserView(browser);

JxBrowser 7和6使用不同的许可证密钥。我假设您为JxBrowser 7请求了30天的免费评估密钥，并尝试将其与JxBrowser 6一起使用。它将无法正常工作。如果您具有JxBrowser 7的有效许可证密钥，则不应使用JxBrowser 6。

我建议您更新示例，并在Java应用程序中仅使用JxBrowser 7：

Engine engine = Engine.newInstance(
        EngineOptions.newBuilder(HARDWARE_ACCELERATED)
                .licenseKey("########")
                .build());
System.setProperty("jxbrowser.license.key","##########");
//BrowserUtil;
Browser browser = engine.newBrowser();
BrowserView view = BrowserView.newInstance(browser);
GoogleMapsPanel.add(view,BorderLayout.CENTER);
browser.on(TitleChanged.class,event -> setTitle(evt.getTitle()));
browser.on(ConsoleMessageReceived.class,event -> 
        System.out.println("LOG: " + evt.getMessage()));

browser.navigation().on(FrameLoadFinished.class,event -> {
    event.frame().browser().zoom().level(ZoomLevel.P_80);
});
browser.navigation().loadUrl("/Users/jacksonseow/NetBeansProjects/PleaseWork/src/pleasework/googlemaps.html");
