PhoenixQueryUtils：

public class PhoenixQueryUtils {

    private static BasicDataSource dataSource = null;
    private static QueryRunner runner;

    private PhoenixQueryUtils() {
    }

    private synchronized static void init() throws SQLException {
        if (dataSource != null) {
            try {
                dataSource.close();
            } catch (SQLException ex) {
                DbUtils.printStackTrace(ex);
            }
        }
        dataSource = null;
        InputStream in = Object.class.getResourceAsStream("/pheonix_jdbc.properties");
        Properties props = new Properties();
        try {
            props.load(in);
            dataSource = BasicDataSourceFactory.createDataSource(props);
            runner = new QueryRunner(dataSource);
        } catch (IOException ex) {
            throw new SQLException(ex);
        } catch (Exception ex) {
            throw new SQLException(ex);
        }

    }

    public static List<Object[]> getAllResults(String sql, Object[] params) throws SQLException {
        if (runner == null) {
            init();
        }
        List<Object[]> ojbs = runner.query(sql, new ArrayListHandler(), params);
        return ojbs;
    }

    public static Object[] getFirstResult(String sql, Object[] params) throws SQLException {
        if (runner == null) {
            init();
        }
        Object[] ojbs = runner.query(sql, new ArrayHandler(), params);
        return ojbs;
    }

    public static Map<String, Object> getFirstResultMap(String sql, Object[] params) throws SQLException {
        if (runner == null) {
            init();
        }
        Map<String, Object> map = runner.query(sql, new MapHandler(), params);
        return map;
    }

    public static Object getResultMaps(String sql, Object[] params) throws SQLException {
        if (runner == null) {
            init();
        }
        List<Map<String, Object>> list = runner.query(sql, new MapListHandler(), params);
        return list;
    }

    public static synchronized Connection getConnection() throws SQLException, IOException, Exception {
        Connection conn = null;
        if (dataSource == null) {
            init();
        }
        if (dataSource != null) {
            conn = dataSource.getConnection();
        }
        return conn;
    }

}

用例：

public static void main(String[] args) {
        
        try {
            List<Object[]> list = PhoenixQueryUtils.getAllResults("select id,   a,  b ,  c ,  d  from test ",
                    new Object[]{});
            System.out.println("id  	 a 	  b 	 c 	 d");
            for (Object[] objs : list) {
                for (Object obj : objs) {
                    System.out.print(obj + "	");
                }
                System.out.println();
            }
        } catch (SQLException ex) {
            DbUtils.printStackTrace(ex);
        }
        System.exit(0);
    }

输出：
