笔记

1、登录笔记：

①局用户获取多个车站id方式一：
User user = this.getUser();
Set<String> stationIds = this.getStationIds(user);

②局用户获取多个车站id方式二：

Set<String> stationIds = getStationIds();

③获取单个车站id：

String id = getStation().getId();

④获取站码的公共方法;

if (StringUtils.isBlank(stationCode)) {
   stationCode = getStation().getStationTelecode();
}

2、sql拼接：

@Override
    public JSONObject listDeviceByIds(IdsForm idsForm, Set<String> stationIds, String userId) {

        StringBuffer sql = new StringBuffer();
        sql.append("select d.s_id, d.s_name , d.s_device_code,dc.s_name as dc_name, sd.s_station_name, ");
        sql.append(" srd.s_name as srd_name,d.s_address,d.d_enable_date,d.d_warranty_end_date, d.i_status  ");
        sql.append(" from rec_device d left join rec_device_category dc on d.s_device_category_id = dc.s_id ");
        sql.append(" left join b_station_dict sd on d.s_station_id = sd.s_id ");
        sql.append(" left join b_station_region_dict srd on d.s_station_region_id = srd.s_id ");
        sql.append(" where 1=1 ");
        Map<String, Object> param = new HashMap<>(2);

        sql.append(" and d.s_id in (:ids) ");
        param.put("ids", idsForm.getIds());

//        if(!CollectionUtils.isEmpty(stationIds)) {
//            sql.append(" and d.s_station_id in ( :stationIds) ");
//            param.put("stationIds", stationIds);
//        }

        List<DeviceImportVO> list = deviceDao.findListBySql(DeviceImportVO.class, sql.toString(), param);
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("content", list);
        return jsonObject;
    }
