然后把多条数据，放在一个结果集里。

public Map<String, Object> NotifyABItem(Map<String, Object> params) {
    log.getLogger("notifynew_s").info("notify.NotifyItem.bodys({},{})", params);
    Map<String, Object> response = new HashMap<String, Object>();
    String notifySettingKey = params.get("notifySettingKey").toString();
    List<String> groupNameList = notifySettingMapper.selectGroupNameListByNotifySettingKey(notifySettingKey);
    int ratA = 0;
    for (int d = 0; d< groupNameList.size(); d++) {
        String groupNameString = groupNameList.get(d);
        params.put("groupName",groupNameString);
    List<Map<String, Object>> notifyRecord = notifySettingMapper.selectNotifyABItem(params);

    response.put(groupNameString, notifyRecord);}

    response.put("status", "OK");
    log.getLogger("notifynew_s").info("notify.NotifyItem.bodys({},{})", params, response);
    return response;
}
