手动点击刷新后才显示
js(index页面，一进去ready完后，进controller)
$(function(){ var url = "<%=request.getContextPath()%>/announcement/selectIndexLimits"; $.post(url); });
controller
@RequestMapping("/selectIndexLimits")
public String selectIndexLimits(HttpServletRequest request){
List<Announcement> announcementIndex = announcementService.selectLimits(0,
5);
request.getSession().setAttribute("announcementIndex", announcementIndex);
// model.addAttribute("announcementIndex", announcementIndex);
return "index";
}
前台显示是el
<c:forEach items="${announcementIndex}" var="announcementIndex">
<tr>
<td><%=++annoi%></td>
<td><a onclick='showAnnoContent(this)'>${announcementIndex.title }</a></td>
<td hidden='hidden'>${announcementIndex.name }</td>
<td hidden='hidden' class='annoContent'>${announcementIndex.content }</td>
<td>${announcementIndex.time}</td>
</tr>
</c:forEach>

已解决，后台跳转失效，但就算有效此方法也不可取。换了写法
