springmvc 下拉框对应

<option value="${titleinfo.shopname}"
<c:if test="${titleinfo.shopname eq shop.shopname}"> selected = "selected"</c:if> 
>${shop.shopname}</option>      //下拉框加判断才会对应起来

@RequestMapping(value = { "/Update"}, method = RequestMethod.GET)
public String updatePage(Model model, ServletRequest request) {
List<BtyShop> list = btyShopService.ListAll();
request.setAttribute("list", list);
List<Region> reg = regionService.ListAll();
request.setAttribute("reg", reg);             //请求过程中调用Service方法返回reg对象，将"reg"传回前台，前台使用items="${reg}"接收   var="shop" 并设置使用对象为shop

String title = request.getParameter("title");
Info titleinfo = infoService.selectBytitle(title);
request.setAttribute("titleinfo", titleinfo);
return "app/Info/Update";
}
