SpringMVC 的Model值传到JSP页面中，用EL表达试取不到值

Controller 中返回ModelAndView，

@Override
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ArrayList itemsList=new ArrayList();
Items items_1 = new Items();
items_1.setName("联想笔记本");
items_1.setPrice(6000f);
items_1.setDetail("ThinkPad T430 联想笔记本电脑！");

Items items_2 = new Items();
items_2.setName("苹果手机");
items_2.setPrice(5000f);
items_2.setDetail("iphone6苹果手机！");

itemsList.add(items_1);
itemsList.add(items_2);

ModelAndView mav=new ModelAndView();
mav.addObject("itemsList", itemsList);
mav.setViewName("/WEB-INF/jsp/items/itemsList.jsp");
return mav;
}

JSP中通过EL表的试取值

${a.name }
${a.price }
${a.detail}
修改

在页面显示${a.name}

解决方案

在jsp文件头

<%@ page isELIgnored="false" %>
