jstl获取值需要 request.setAttribute("list", list);

list 里面是对象也要request.setAttribute(“list”, list);
list 也要request.setAttribute(“list”, list);

都可以传递到jsp页面
controller:方法

@SuppressWarnings("unchecked")
@RequestMapping(value = "login")
public String login(HttpServletRequest request,Users user){ 
    String password= user.getPassword();
     users=usersBiz.login(user);
     if(users != null){
         if(password.equals(users.getPassword().trim())){
             list=usersBiz.find();

             request.setAttribute("list", list);
             return "index";
         }
     }
     return "login";
}

jsp:对应着键

<c:forEach items="${list }" var="user">
    <tr>    
        <td>${user.id } </td>
        <td>${user.uname }</td>
        <td>${user.pwd }</td>
        <td>delete</td>
    </tr>
    </c:forEach>
