JAVA文件搜索系统连接MysqlGUI界面代码

以下是一个简单的Java文件搜索系统连接MySQL数据库并使用GUI界面的示例代码：

import java.sql.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class FileSearch extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;
    JLabel l1, l2;
    JTextField tf1, tf2;
    JButton btn1, btn2;
    JTable j;

    FileSearch() {
        setTitle("File Search System");
        setSize(700, 700);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

        l1 = new JLabel("Search Path:");
        l1.setBounds(50, 50, 100, 30);
        tf1 = new JTextField();
        tf1.setBounds(150, 50, 250, 30);

        l2 = new JLabel("Search Keyword:");
        l2.setBounds(50, 100, 100, 30);
        tf2 = new JTextField();
        tf2.setBounds(150, 100, 250, 30);

        btn1 = new JButton("Search");
        btn1.setBounds(450, 50, 100, 30);
        btn1.addActionListener(this);

        btn2 = new JButton("Clear");
        btn2.setBounds(450, 100, 100, 30);
        btn2.addActionListener(this);

        add(l1);
        add(tf1);
        add(l2);
        add(tf2);
        add(btn1);
        add(btn2);

        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == btn1) {
            String path = tf1.getText();
            String keyword = tf2.getText();
            try {
                Class.forName("com.mysql.jdbc.Driver");
                Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/files", "root", "password");
                Statement stmt = con.createStatement();
                ResultSet rs = stmt.executeQuery("SELECT * FROM filesearch WHERE path LIKE '%" + path + "%' AND content LIKE '%" + keyword + "%'");
                String[] columns = {"File Name", "Path", "Content"};
                String[][] data = new String[100][3];
                int i = 0;
                while (rs.next()) {
                    data[i][0] = rs.getString("name");
                    data[i][1] = rs.getString("path");
                    data[i][2] = rs.getString("content");
                    i++;
                }
                j = new JTable(data, columns);
                j.setBounds(50, 200, 600, 400);
                JScrollPane sp = new JScrollPane(j);
                add(sp);
                con.close();
            } catch (Exception ex) {
                System.out.println(ex);
            }
        } else if (e.getSource() == btn2) {
            tf1.setText("");
            tf2.setText("");
        }
    }

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

在此示例中，我们使用了MySQL数据库来存储文件路径、文件名和文件内容。在搜索时，我们使用`LIKE`子句来匹配搜索路径和关键字。然后，我们将结果显示在一个JTable中。注意，这个示例只是一个简单的演示，你需要根据自己的需求进行修改和扩展。同时，你需要添加MySQL数据库的驱动程序到你的类路径中。
