Question

我想在微软的帮助下阅读word文档，但这仅限于我的java表单。在microsoft word的帮助下，该文档将以java形式打开。

如下图所示，我想开发一些东西：

用户可以根据需要编辑文档。但是当他们想要保存文档时，文档将保存在远程计算机中。

我可以通过以下代码在microsoft word的帮助下打开word文档：

try {
            /* if (Desktop.isDesktopSupported()) {
                  Desktop.getDesktop().open(new File("E:\\finger.docx"));
             }*/
            Process p = Runtime.getRuntime()
                .exec("rundll32 url.dll,FileProtocolHandler E:\\finger.docx");
             p.waitFor(); 
            System.out.println("Done.");
        } catch (IOException ioe) {
              ioe.printStackTrace();
        }
        catch (InterruptedException ex) {
                Logger.getLogger(JavaFromWord.class.getName()).log(Level.SEVERE, null, ex);
            }

但我不知道如何在JForm中嵌入单词viewer。请帮我。

Answer 1

正如其他人所指出的，这听起来很像XY问题 - 意思是，你已经确定最好的解决方案是使用Microsoft Word，所以你问的是如何嵌入Microsoft Word而不是询问你的实际目标，这似乎是在用户界面中加入格式化文本。

执行此操作的好方法是使用包含HTML内容的JEditorPane：

import java.awt.EventQueue;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JScrollPane;

public class HtmlPane {
    static void show() {
        JEditorPane content = new JEditorPane("text/html",
            "<p>" +
            "The process of finger enrollment is now to be done in database." +
            " Previously it was done in file template." +
            " There are several reasons behind this:" +
            "<ol>" +
            "<li>" +
            "Time:<br>" +
            "--------" +
            "<p>" +
            "The process of verification in file template based method takes" +
            " 6.9 s on average.  On the other hand, in database based method," +
            " it takes only 3.5 s." +
            "<p>" +
            "The code for determining time is as follows:" +
            "<blockquote>" +
            "<pre>" +
            "Dim StartTime, Elapsed Time\n" +
            "StartTime = Timer\n" +
            "ElapsedTime = Timer.CheckTime\n" +
            "</pre>" +
            "</blockquote>" +
            "</ol>");

        content.setEditable(false);

        JFrame frame = new JFrame("finger");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(new JScrollPane(content));

        frame.pack();
        frame.setLocationByPlatform(true);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> show());
    }
}

（注意：Swing HTML渲染器仅支持HTML 3.2。）

如果您不熟悉HTML，我建议您学习它。基本HTML 非常易于编写。另外，您需要了解基本HTML才能成为有效的Java程序员，因为专业开发需要编写javadoc，所有javadoc都是HTML格式。
