Question

我尝试从数据库中检索数据并将其填充到Jlist中。之后，当我单击Jlist时，数据将填充到3个文本字段。其中两个将以html文件的形式填充到Jeditorpane作为组合。我尝试了以下方法，但它会产生错误。

String meaning1 = txtMeanings.getText();
String source1 = txtSources.getText();
String htmlText = "<html>"
        + "<body>"
        + "<div class='content'>{meaning1}</div>"
        + "<div class='footer'>{source1}</div>"
        +"</body>"
         + "</html>";
JScrollPane scrollPane_1 = new JScrollPane();
    scrollPane_1.setBounds(10, 40, 529, 387);
    panel_2.add(scrollPane_1);

     HTMLEditorKit hed = new HTMLEditorKit();
        StyleSheet ss = hed.getStyleSheet();
        ss.addRule("BODY {...}");
        ss.addRule("h1{...}");
        ss.addRule("p{...}");
        ss.addRule("blockquote{...}");
        ss.addRule("#title{...}");
        ss.addRule("hr{...}");
        ss.addRule("#content{ ...}");
        ss.addRule("#footer{...}");
        Document doc = hed.createDefaultDocument();

        editorPane = new JEditorPane();
        editorPane.setContentType("text/html");
        editorPane.setEditorKit(hed);
        editorPane.setDocument(doc);
        editorPane.setEditable(false);
        scrollPane_1.setViewportView(editorPane);
ListboxEntry.addListSelectionListener(new ListSelectionListener() {
        public void valueChanged(ListSelectionEvent arg0) {

            try
    {
        String query ="select EntryLists, Meanings, Sources from Entry where EntryLists like ? ";
        PreparedStatement pst=Connection.prepareStatement(query);

        pst.setString(1,(String)ListboxEntry.getSelectedValue());
        ResultSet rs=pst.executeQuery();


        while(rs.next())
        {
            txtEntry.setText(rs.getString("EntryLists"));
            txtMeanings.setText(rs.getString("Meanings"));
            txtSources.setText(rs.getString("Sources"));

        }

        pst.close();
        rs.close();
    } catch (Exception e) {
        e.printStackTrace();}



             editorPane.setText(htmlText);
        }
    });

我该怎么办？有可能直接将两个数据（含义和来源）填充到Jeditorpane而不在两个文本字段中首先填充它吗？在VB.Net中，我简单地通过这个简单的代码来解决问题：

 WebBrowser1.DocumentText = String.Format("<html><head><style><!--body{{....}}--></style></head></head><body><div id=content>{0}</div><div id=footer><b>Notes:<br></b>{1} </div></body></html>", txtMeanings.Text, txtSources.Text)

如何用Java做到这一点？

我通过更改为以下代码来解决自己的问题：

ListboxEntry.addListSelectionListener(new ListSelectionListener() {
    public void valueChanged(ListSelectionEvent arg0) {

        try
{
    String query ="select EntryLists, Meanings, Sources from Entry where EntryLists like ? ";
    PreparedStatement pst=Connection.prepareStatement(query);

    pst.setString(1,(String)ListboxEntry.getSelectedValue());
    ResultSet rs=pst.executeQuery();


    while(rs.next())
    {
        txtEntry.setText(rs.getString("EntryLists"));
        txtMeanings.setText(rs.getString("Meanings"));
        txtSources.setText(rs.getString("Sources"));

    }

    pst.close();
    rs.close();
} catch (Exception e) {
    e.printStackTrace();}
String htmlText = "<html>"
    + "<body>"
    + "<div class='content'>"+ txtMeanings.getText() +"</div>"
    + "<div class='footer'>"+ txtSources.getText() +"</div>"
    +"</body>"
     + "</html>";

         editorPane.setText(htmlText);
    }
});

但是，如果有人想改进它，欢迎提出建议。

如何将数据从两个文本域传递给Jeditorpane作为html？
