JavaFX WebView：启动程序、输入数据、服务和显示本地HTML->Refresh Data=Refresh WebView

Question

如果我关闭并重新打开，然后再点击我的按钮，WebView现在会显示新的数据。

我确信问题在于我使用的是getClass（）.getResource（String）：

URL link = getClass().getResource("EmailSigTest.html");
engine = webView.getEngine();
engine.load(link.toString());

我如何使这个东西动态变化，即：

1. Input data
2. Write File
3. Refresh WebView to reflect new html doc

public class SignatureGenFXMLDocController implements Initializable {
    private String firstName, lastName, directLine, title, cellPhone, lineOne, lineTwo;
    boolean social = false;
    @FXML private TextField txtFirstName, txtLastName, txtDirectLine, txtTitle, txtCellPhone;
    @FXML private CheckBox chkSocialIcons;
    @FXML Button btnGenerate;
    @FXML WebView webView;
    @FXML WebEngine engine;

    @FXML private void handleButtonAction(ActionEvent event) throws InterruptedException {
        System.out.println("You clicked me!");
        firstName = txtFirstName.getText();
        lastName = txtLastName.getText();
        directLine = txtDirectLine.getText();
        title = txtTitle.getText();
        cellPhone = txtCellPhone.getText();

        writeHtml();
        readHtml();
    }

    @Override
    public void initialize(URL url, ResourceBundle rb) {

    }
    private void writeHtml(){
        // Configurae Freemarker
    Configuration cfg = new Configuration();
    try {
        // Load the template
        Template template = cfg.getTemplate("src/signaturegen/template.ftl");
        Map<String, Object> data = new HashMap<String, Object>();

            data.put("fName", firstName);
            data.put("lName", lastName);
            data.put("title", title);
            data.put("dLine", directLine);
            data.put("social", social);

            Writer console = new OutputStreamWriter(System.out);
            template.process(data, console);
            console.flush();
            // File output
            Writer file = new FileWriter (new File("build/classes/signaturegen/EmailSigTest.html"));
            template.process(data, file);
            file.flush();
            file.close();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (TemplateException e) {
            e.printStackTrace();
        }
    }     
    private void readHtml(){
        URL link = getClass().getResource("EmailSigTest.html");
        engine = webView.getEngine();
        engine.load(link.toString());
    }
}

正如本问题中所讨论的，在webview中重新加载相同的URL不起作用。

您可能希望尝试将重新加载委托给页面本身中的JavaScript。为此，您在页面中定义了一个函数：

function reloadMe() {
  location.reload();
}

并从Java调用此函数：

private void readHtml(){
    URL link = getClass().getResource("EmailSigTest.html");
    engine = webView.getEngine();
    engine.executeScript("reloadMe();"); 
}

null
