用el表达式取不到model.addAttribute的值解决思路

用el表达式取不到model.addAttribute的值
后台代码：
@Controller
@RequestMapping("/publisher")
public class StatisticalRest
{
    @Autowired
    private StatisticalService statisticalService;

    @RequestMapping(value = "statistical")
    public String payDetailList(@ModelAttribute("model")
    StatisticalModel pageModel, BindingResult result, Model model,
            HttpSession session)
    {
        String userId = StringUtil.objToStr(session
                .getAttribute(Constants.SESSION_USERID));
        String retUrl = AdminUrl.OUTLINE;
        // 标题
        pageModel.setPageTitle("统计结果");

        // 数据取得
        statisticalService.getStatisticalDetailByTime(pageModel, userId);

        // 模型绑定
        model.addAttribute("model", pageModel);
        return retUrl;
    }

}

前台jsp

<ul>
<li style="width:160px;"><span class="num" >${model.courseNum}</span><span class="desc">发布课程</span></li>
<li style="width:160px;"><span class="num" >50</span><span class="desc">销售课程</span></li>
<li><span class="num">${pageContext.request.contextPath}</span><span class="desc">累计销售金额</span></li>
<li><span class="num">${model.rewardMoney}</span><span class="desc">累计获得红包</span></li>
<li><span class="num">${model.sumMoney}</span><span class="desc">累计收入金额</span></li>
</ul>


${model.courseNum}取不到值 页面上什么都不显示
${pageContext.request.contextPath}能够显示 

显示效果如下

------解决思路----------------------
@ModelAttribute("model")
    StatisticalModel pageModel，这句没获取到结果吧
