Estou com dúvida no curso de Design Patterns para Bons Programadores 2, no exercício do capítulo Fábricas e o problema de criação de objetos.

Seria ruim usar o Strategy com Factory para resolver este exercício?

package Factory;

import java.sql.Connection;

public class TestaConnectionFactory {

    public static void main(String[] args) {
        Connection conexao = new ConnectionFactory().getConnection(new MySQL());
    }
}

package Factory;

import java.sql.Connection;

public class ConnectionFactory {

    public Connection getConnection(BancoDeDados banco){//renomear para get
        return banco.getConnection();
    }

}

package Factory;

import java.sql.Connection;

public interface BancoDeDados {

    Connection getConnection();

}

package Factory;

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

public class MySQL implements BancoDeDados {

    @Override
    public Connection getConnection() {
        try {
            return DriverManager.getConnection("jdbc:mysql://localhost:3306/banco", "root", "123");
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

}

package Factory;

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

public class Outro implements BancoDeDados {

    @Override
    public Connection getConnection() {
        try {
            return DriverManager.getConnection("jdbc:outrobanco://localhost:3306/banco", "root", "123");
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

}
