如何为 netbeans java 添加 jxbrowser 的许可证密钥？

Question

我正在尝试在我的 java 应用程序中添加 jxbrowser，但我无法运行我的应用程序，因为它一直告诉我找不到我的许可证。我从网站获得了一个免费许可证，我无法在下面的代码中显示许可证密钥，但我想问我如何配置和设置许可证密钥，因为我一直收到错误。你参考下面。我想知道我是否在我的情况下正确设置了许可证。如果您在下面看到，我将许可证密钥替换为全“#”，因为我不能让人们查看它以防万一它被盗。请告诉我如何解决我的问题。

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：

Answer 1

从给定的源代码中，我看到您将 JxBrowser 7 和 6 混合在一个 Java 应用程序中。以下代码属于7：

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

以下行属于 JxBrowser 6：

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

JxBrowser 7 和 6 使用不同的许可证密钥。我假设您申请了 JxBrowser 7 的 30 天免费评估密钥，并尝试将其与 JxBrowser 6 一起使用。它不会那样工作。如果您拥有 JxBrowser 7 的有效许可证密钥，则不应使用 JxBrowser 6。

我建议您更新您的示例并在您的 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");
