spring mvc 结合easyui datagrid 使用responseBody 注解 返回json 无法绑定

今天遇到了这个问题，o(︶︿︶)o 唉，究其原因，太长时间不用easyui了。都忘记怎么用了。

使用 easyui datagrid表格，返回的日期要符合 要求的格式。

给出一份easyui 官方的demo数据格式：

{"total":28,"rows":[
{"productid":"FI-SW-01","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
{"productid":"K9-DL-01","unitcost":12.00,"status":"P","listprice":18.50,"attr1":"Spotted Adult Female","itemid":"EST-10"},
{"productid":"RP-SN-01","unitcost":12.00,"status":"P","listprice":28.50,"attr1":"Venomless","itemid":"EST-11"},
{"productid":"RP-SN-01","unitcost":12.00,"status":"P","listprice":26.50,"attr1":"Rattleless","itemid":"EST-12"},
{"productid":"RP-LI-02","unitcost":12.00,"status":"P","listprice":35.50,"attr1":"Green Adult","itemid":"EST-13"},
{"productid":"FL-DSH-01","unitcost":12.00,"status":"P","listprice":158.50,"attr1":"Tailless","itemid":"EST-14"},
{"productid":"FL-DSH-01","unitcost":12.00,"status":"P","listprice":83.50,"attr1":"With tail","itemid":"EST-15"},
{"productid":"FL-DLH-02","unitcost":12.00,"status":"P","listprice":63.50,"attr1":"Adult Female","itemid":"EST-16"},
{"productid":"FL-DLH-02","unitcost":12.00,"status":"P","listprice":89.50,"attr1":"Adult Male","itemid":"EST-17"},
{"productid":"AV-CB-01","unitcost":92.00,"status":"P","listprice":63.50,"attr1":"Adult Male","itemid":"EST-18"}
]}

我们要输出这样的格式其实也不难。使用spring mvc 容易就做到了。

public @ResponseBody Map<String, Object>findall(int page,int rows) {
List<Logininfo> logininfos = logininfoBiz.searchAll(page,rows);//访问数据层,得到数据
int count=logininfoBiz.searchCount();//访问数据层 得到总数量
Map<String, Object> map = new HashMap<String, Object>();
map.put("rows", logininfos);
map.put("total", count);
return map;
}
