树形dgCol列怎么引用TreeGrid.attributes中的值
请高手指点页面代码：
< t:datagrid name="venGoodsSortList" title="商器类型" actionUrl="venGoodsSortController.do?datatreegrid" idField="id" treegrid="true" pagination="false" fit="true">
....
<t:dgCol title="拼音编码" field="gsSpell" treefield="attributes.get('gsSpell')" width="80"></t:dgCol>
....
后台代码：
@RequestMapping(params = "datatreegrid")
@ResponseBody
public List<TreeGrid> datatreegrid(HttpServletRequest request, TreeGrid treegrid) {
CriteriaQuery cq = new CriteriaQuery(VenGoodsSortEntity.class);
if(treegrid.getId() == null)
cq.add(Restrictions.isNull("gsParentSort.id"));
else
cq.add(Restrictions.eq("gsParentSort.id", treegrid.getId()));
List<VenGoodsSortEntity> goodSortList = venGoodsSortService.getListByCriteriaQuery(cq, false);
List<TreeGrid> treeGrids = new ArrayList<TreeGrid>();
for(VenGoodsSortEntity goodSort: goodSortList) {
TreeGrid tg = new TreeGrid();
tg.setId(goodSort.getId());
if(goodSort.getGsParentSort() == null) {
tg.setParentId(null);
tg.setParentText("");
}
else {
tg.setParentId(goodSort.getGsParentSort().getId());
tg.setParentText(goodSort.getGsParentSort().getGsName());
}
tg.setCode(goodSort.getGsCode());
tg.setText(goodSort.getGsName());
Map<String, String> map = new HashMap<String, String>();
tg.setAttributes(map);
map.put("gsSpell", goodSort.getGsSpell());
tg.setState("closed");
treeGrids.add(tg);
}
return treeGrids;
}
