Spring MVC控制层封装的数据在前台如何访问？

Controller层封装的数据如下：

@RequestMapping("searchByCondition")
public ModelAndView searchByCondition(HttpServletRequest request,ModelAndView mv){
String type = request.getParameter("type");
String content = request.getParameter("content");
List<Problem> list = new ArrayList<Problem>();
try{
list = service.searchByCondition(type, content);
mv.addObject("list", list);
mv.setViewName("jsp/searchByCondition");
}catch(NullPointerException ex){
ex.printStackTrace();
}
return mv;
}

前台访问如下，通过jstl标签循环输出：

<div class="main_body_left">
       <c:forEach var="list" items="${list}">
       <p>${list.title }</p>
       <p>${list.content}</p>
       </c:forEach>
        </div>

如何取得list的长度？

<span class="result">我们为您找到相关结果约${list.size()}个</span>
