jdbc查询结果集result转换成对应list集合

public static <T> List<T> convertToList(ResultSet rs,Class<T> t) throws SQLException {
        List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
        ResultSetMetaData md = (ResultSetMetaData) rs.getMetaData();
        int columnCount = md.getColumnCount();
        while (rs.next()) {
            Map<String, Object> rowData = new HashMap<String, Object>();
            for (int i = 1; i <= columnCount; i++) {
                rowData.put(md.getColumnName(i), rs.getObject(i));
            }
            list.add(rowData);
        }
        JSONArray jr = JSONArray.fromObject(list);
        List<T> resultList = JSONArray.toList(jr, t);
        return resultList;
    }
