老师，关于用户状态显示问题

我想要通过这样的方式显示状态，可是不可以，但不知道问题在哪里

<c:if test="${listOne.userStatus==0}">
    <td class="text-center fw600">${Contant.NORMAL}</td>
</c:if>
<c:if test="${listOne.userStatus==1}">
    <td class="text-center fw600">${Contant.LOCK}</td>
</c:if>
<c:if test="${listOne.userStatus==2}">
    <td class="text-center fw600">${Contant.DEL}</td>
</c:if>

package com.imooc.bbs.global;

public class Contant {
//    用户状态
public static final String NORMAL="正常";
public static final String LOCK="锁定";
public static final String DEL="删除";
}

package com.imooc.bbs.controller;

import com.imooc.bbs.biz.PostBiz;
import com.imooc.bbs.biz.UserBiz;
import com.imooc.bbs.entity.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import javax.servlet.http.HttpSession;
import java.util.Map;

@Controller("userController")
@RequestMapping("user")
public class UserController {
@Autowired
    private UserBiz userBiz;
@RequestMapping("/list")
public String list(Map<String, Object> map) {
        map.put("list", userBiz.getAll());
return "user_list";
    }

@RequestMapping("/listOne")
public String listOne(HttpSession httpSession, Map<String, Object> map) {
User user = (User) httpSession.getAttribute("user");
        map.put("listOne", userBiz.getByUserName(user.getUsername()));
return "pre_newpost";
    }

@RequestMapping("/remove")
public String remove(Integer id) {
userBiz.remove(id);
return "redirect:list";
    }

}
