jdbc查询结果集result转换成对应list集合 java实现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;
  }
