有不同的方法可以做到这一点。一种方法是简单地避免插入符号可见性调整，如下所示：
import java.awt.Rectangle;import javax.swing.JButton;import javax.swing.JEditorPane;import javax.swing.Jframe;import javax.swing.JScrollPane;import javax.swing.SwingUtilities;import javax.swing.event.HyperlinkEvent;import javax.swing.event.HyperlinkListener;import javax.swing.text.DefaultCaret;public class TestEditorPane implements HyperlinkListener { private final class MyCaret extends DefaultCaret { @Override protected void adjustVisibility(Rectangle nloc) { } } JEditorPane dataDisplayer = new JEditorPane(); private MyCaret caret; @Override public void hyperlinkUpdate(HyperlinkEvent arg0) { dataDisplayer.setText("<a href=''>Change Text</a><br><br><br><br><br><br><br><br><br><br>bla bla"); } public void init() { Jframe frame = new Jframe(); dataDisplayer.setEditable(false); caret = new MyCaret(); dataDisplayer.setCaret(caret); dataDisplayer.add(new JButton()); dataDisplayer.setContentType("text/html"); JScrollPane jsp = new JScrollPane(dataDisplayer); dataDisplayer.setText("<a href=''>Change Text</a><br><br><br><br><br><br><br><br><br><br>bla"); this.dataDisplayer.addHyperlinkListener(this); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.setContentPane(jsp); frame.pack(); frame.setVisible(true); } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { new TestEditorPane().init(); } }); }}
