改变用户状态的问题

老师，前后台是分开的。代码如下 以回帖为例 ------------前台控制器中------------------- @RequestMapping(value = "pre_comment") public String preComment(@RequestParam(value = "pid") Integer pid,HttpSession session, Map<String,Object> map){ //获取当前Post对象 Post post = postService.get(pid); Comment comment = new Comment(); comment.setPost(post); map.put("post", post); map.put("comment",comment); //获取当前登录的用户对象 map.put("user", (User)(session.getAttribute("user"))); //获取发帖人的User对象 User postUser = userService.getByName(post.getUsername()); map.put("postUser", postUser); //获取统计相关的数据 map.put("list", postService.getAll()); List<User> allUsers = userService.getAll(); map.put("allUsers", allUsers); List<Comment> allComments = commentService.getAll(); map.put("allComments", allComments); return "new_comment"; } @RequestMapping(value = "comment") public String comment(HttpSession session,Comment comment, Map<String,Object> map){ User user = (User)session.getAttribute("user"); comment.setUsername(user.getUsername()); comment.setPostId(comment.getPost().getId()); comment.setCreateTime(new Date()); comment.setUserId(user.getId()); commentService.add(comment); return "redirect:pre_comment?pid="+comment.getPostId(); }

---------------new_comment.jsp中---------------------- <div class="panel panel-default"> <div class="panel-heading"> 发表回复 </div> <div class="panel-body"> <div class="reply-box form"> <!-- 已经登录的情况 --> <c:if test="${user!=null&&user.userStatus!=1&&postUser.userStatus!=2}"> <form:form modelAttribute="comment" action="comment" accept-charset="UTF-8" id="thread_create_form" cssClass="create_form"> <%--<input type="hidden" name="postId" value="<!-- 此处存放帖子id -->">--%> <form:hidden path="post.id" cssClass="hidden"/> <div class="form-group"> <form:textarea path="content" cssClass="post-editor form-control" rows="5" style="overflow:hidden" id="content" placeholder="请使用Markdown撰写内容" name="content" cols="50"></form:textarea> </div> <div class="form-group status-post-submit"> <input class="btn btn-primary col-xs-2" id="thread-create-submit" type="submit" value="回复"> </div> </form:form> </c:if>

<%--账户被锁定时不能回帖--%> <c:if test="${user.userStatus==1}"> <div style="padding:20px;color: red"> 用户已被锁定,请联系管理员! </div> </c:if> <!-- 未登录的情况 --> <c:if test="${user==null}"> <div style="padding:20px;"> 需要 <a class="btn btn-success" href="/post/pre_login">登录</a> 后方可回复, 如果你还没有账号请点击这里 <a class="btn btn-primary" href="/post/pre_reg">注册</a>。 </div> </c:if> <%--发帖账户被删除时其他用户不能回帖--%> <c:if test="${postUser.userStatus==2}"> <div style="padding:20px;color: red"> 主题帖已删除,无法进行回复！ </div> </c:if> ---------后台用户控制器中--------- //删除用户 @RequestMapping("user_delete") public String delete(@RequestParam(value = "uid") Integer uid, HttpSession session){ //根据要删除的用户id得到用户 User user = userService.get(uid); //改变用户的状态 user.setUserStatus(2); userService.edit(user); session.setAttribute("user",user); return "redirect:user_list"; }

老师，我在后台的HttpSession中更新了用户的信息，但前台的HttpSession中用户的信息并未发生改变，后台的修改用户信息的方法和前台的帖子相关方法是两个独立的方法，请问该怎么做呢？
