java 将list中name,对应的id放入map

private Map<String, Long> smfname_allowValue() throws Exception {ItemQueryVO queryVO = new ItemQueryVO();List<ItemResultVO> list = itemService.selectAllCategCode(queryVO);//查询list结果集Map<String, Long> allowValues = Maps.newHashMap();//存name,id结果mapif (CollectionUtils.isNotEmpty(list)) {//循环存值    for (ItemResultVO res : list) {        allowValues.put(res.getItemname(), res.getId());    }}return allowValues;}
