具有自动连接到不同参数的构造函数的实现的设计模式

public class ConnectionFactory {
    public static Connection createConnection(String type) {
        if (type.equals("MySQL")) {
            return new MySQLConnection();
        } else if (type.equals("Oracle")) {
            return new OracleConnection();
        } else if (type.equals("SQLServer")) {
            return new SQLServerConnection();
        } else {
            throw new IllegalArgumentException("Invalid connection type: " + type);
        }
    }
}

public interface Connection {
    void connect();
}

public class MySQLConnection implements Connection {
    @Override
    public void connect() {
        // 连接到MySQL数据库的逻辑
    }
}

public class OracleConnection implements Connection {
    @Override
    public void connect() {
        // 连接到Oracle数据库的逻辑
    }
}

public class SQLServerConnection implements Connection {
    @Override
    public void connect() {
        // 连接到SQL Server数据库的逻辑
    }
}
