Treegrid的动态加载实例代码

废话不多说了，直接给大家贴代码了。

具体代码如下所示：

1、前端

<%@ page language="java" pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>

2、controller

@RequestMapping("/treegrid")
@ResponseBody
public List treegrid(GoodsTypePage goodsTypePage) {
if(null==goodsTypePage || "".equals(goodsTypePage.getId()) || null == goodsTypePage.getId()){
goodsTypePage.setId("NULL");
}
return goodsTypeService.treegrid(goodsTypePage);
}

3、service

@Override
// 缓存数据
public List treegrid(GoodsTypePage goodsTypePage) {
String hql = "";
if(null==goodsTypePage || "".equals(goodsTypePage.getId()) || "NULL".equals(goodsTypePage.getId())){
hql = "from GoodsType t where t.tgoodstype.id is NULL order by t.seq";
}else{
hql = "from GoodsType t where t.tgoodstype.id = '" +goodsTypePage.getId()+"' order by t.seq";
}
List brList = goodsTypeDao.find(hql);
List nl = new ArrayList();
if (brList != null && brList.size() > 0) {
for (GoodsType br : brList) {
GoodsTypePage r = new GoodsTypePage();
BeanUtils.copyProperties(br, r);
if(br.getTgoodstype()!=null){
r.setPname(br.getTgoodstype().getText());
r.setPid(br.getTgoodstype().getId());
}
r.setState("closed");
nl.add(r);
}
}
return nl;
}
