public static String queryAll() { Connection conn = null; Statement sta = null; ResultSet rs = null; try { PhoenixDB pDB = new PhoenixDB(); conn = pDB.getConn(); sta = conn.createStatement(); rs = sta.executeQuery("select * from tb"); ResultSetMetaData md = rs.getMetaData(); //获得结果集结构信息,元数据 int columnCount = md.getColumnCount(); //获得列数 while (rs.next()) { List<Object> l = new ArrayList<Object>(); for (int i = 1; i <= columnCount; i++) { l.add(rs.getObject(i)); } list.add(l); } } catch (SQLException e) { e.printStackTrace(); } return "success"; } 将JDBC ResultSet结果集转成List
