用swing做一个简单的正则验证工具

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);
	}
}
