如何在AsyncTask中快速重新连接到数据库？

public class DatabaseTask extends AsyncTask<Void, Void, Void> {
    private static final int MAX_RETRY = 3;
    private static final long RETRY_DELAY = 1000; // 1 second

    private Connection connection;
    private int retryCount;

    @Override
    protected Void doInBackground(Void... params) {
        try {
            connection = createConnection();
            // 执行数据库操作
        } catch (SQLException e) {
            handleConnectionError(e);
        }
        return null;
    }

    private Connection createConnection() throws SQLException {
        // 创建数据库连接
        return DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb", "username", "password");
    }

    private void handleConnectionError(SQLException e) {
        if (retryCount < MAX_RETRY) {
            retryCount++;
            try {
                Thread.sleep(RETRY_DELAY);
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
            doInBackground();
        } else {
            e.printStackTrace();
            // 达到重试次数限制，可以选择放弃连接或者抛出异常
        }
    }

    @Override
    protected void onPostExecute(Void result) {
        // 执行完成后的操作
    }
}
