从服务器获取数据库名称

import java.sql.*;

public class GetDatabaseName {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try {
            // 建立数据库连接
            Connection connection = DriverManager.getConnection(url, username, password);

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

            // 执行查询
            ResultSet resultSet = statement.executeQuery("SELECT DATABASE()");

            // 解析结果
            if (resultSet.next()) {
                String databaseName = resultSet.getString(1);
                System.out.println("当前连接的数据库名称是：" + databaseName);
            }

            // 关闭连接
            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
