eclipse怎么与mysql数据库连接

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class DatabaseConnection {
    public static void main(String[] args) {
        Connection conn = null;
        try {
            // 加载JDBC驱动程序
            Class.forName("com.mysql.cj.jdbc.Driver");

            // 创建数据库连接
            String url = "jdbc:mysql://localhost:3306/your_database_name";
            String username = "your_username";
            String password = "your_password";
            conn = DriverManager.getConnection(url, username, password);

            // 连接成功，执行您的数据库操作

        } catch (SQLException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } finally {
            try {
                // 关闭数据库连接
                if (conn != null && !conn.isClosed()) {
                    conn.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
