我用笨方法实现的，应该有更好的方法吧！给楼主参考一下吧！好用的话别忘给分啊！

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;

public class Test extends JFrame {
private JTextField textField;
private static final long serialVersionUID = -2397593626990759111L;

private JPanel pane = null;

private MQDocument doc = null;

public Test() {
super("Test");
pane = new JPanel();
pane.setLayout(null);

this.getContentPane().add(pane);

textField = new JTextField(){

public void paint(Graphics g) {
super.paint(g);
Graphics2D g2d = (Graphics2D) g;
g2d.setPaint(Color.BLACK);
g2d.drawLine(0, textField.getHeight() - 1, textField.getWidth(), textField.getHeight() - 1);
}
};
textField.setBorder(null);
textField.setBounds(10, 10, 89, 22);
pane.add(textField);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(270, 370);
this.setVisible(true);
}

public static void main(String args[]) {
new Test();
}

}
