如何使用Java连接到基于Web的Oracle数据库？

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class OracleConnection {
    public static void main(String[] args) {
        try {
            // 加载JDBC驱动程序
            Class.forName("oracle.jdbc.driver.OracleDriver");

            // 建立数据库连接
            Connection connection = DriverManager.getConnection(
                    "jdbc:oracle:thin:@localhost:1521:orcl", "username", "password");

            // 创建Statement对象
            Statement statement = connection.createStatement();

            // 执行SQL查询
            ResultSet resultSet = statement.executeQuery("SELECT * FROM employees");

            // 处理查询结果
            while (resultSet.next()) {
                System.out.println("Employee ID: " + resultSet.getInt("employee_id"));
                System.out.println("Employee Name: " + resultSet.getString("employee_name"));
            }

            // 关闭数据库连接
            connection.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
