直接上代码吧，因为我对swing也不熟悉，照着API一点点拼出来的。

import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.util.regex.Matcher;import java.util.regex.Pattern;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JLabel;import javax.swing.JPanel;import javax.swing.JTextField;public class RegExpMatcher {    public static void main(String[] args) {        JFrame frame = new JFrame("正则表达式匹配器");        frame.setSize(350, 150);        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        JPanel panel = new JPanel();        JLabel queryStringLabel = new JLabel("匹配字符串:");        queryStringLabel.setBounds(10, 20, 80, 25);        JTextField queryStringText = new JTextField(20);        queryStringText.setBounds(100, 20, 165, 25);        JLabel regExpLabel = new JLabel("正则表达式:");        regExpLabel.setBounds(10, 50, 80, 25);        JTextField regExpText = new JTextField(20);        regExpText.setBounds(100, 50, 165, 25);        JButton matchButton = new JButton("部分匹配");        matchButton.setBounds(10, 80, 80, 25);        matchButton.addActionListener(new ActionListener() {            @Override            public void actionPerformed(ActionEvent e) {                String queryString = queryStringText.getText().trim();                String regExp = regExpText.getText().trim();                regExp = regExp.replace("\\\\", "\\");                try {                    Pattern pattern = Pattern.compile(regExp);                    Matcher matcher = pattern.matcher(queryString);                    matchButton.setText("" + matcher.find());                } catch (Exception e2) {                    matchButton.setText("error");                    throw e2;                }            }        });        JButton matchFullButton = new JButton("完全匹配");        matchFullButton.setBounds(100, 100, 80, 25);        matchFullButton.addActionListener(new ActionListener() {            @Override            public void actionPerformed(ActionEvent e) {                String queryString = queryStringText.getText().trim();                String regExp = regExpText.getText().trim();                regExp = regExp.replace("\\\\", "\\");                try {                    Pattern pattern = Pattern.compile(regExp);                    Matcher matcher = pattern.matcher(queryString);                    matchFullButton.setText("" + matcher.matches());                } catch (Exception e2) {                    matchFullButton.setText("error");                    throw e2;                }            }        });        panel.add(queryStringLabel);        panel.add(queryStringText);        panel.add(regExpLabel);        panel.add(regExpText);        panel.add(matchButton);        panel.add(matchFullButton);        frame.add(panel);        frame.setVisible(true);    }}
