jsp获取map

1、简单Map

 User user = new User();
    user.setName("zmy");
    user.setAge();
    user.setBirthday(new Date());
    request.setAttribute("user", user);

   Map map = new HashMap();
    map.put("sname","light");
    map.put("gender","male");
    map.put("user",user);
    request.setAttribute("map",map);

${map.sname}、${map.gender}、${map.user.name}

2、c:forEach方式

Map<Integer, Object> map = new HashMap<Integer, Object>();
map.put(, "张三");
map.put(, "李四");
model.addAttribute("map", map);

 <c:forEach items="${map}" var="content">
<span>${content.key}</span>
<span>${content.value}</span>
</c:forEach>
