页面登录的用户名的回显

  @RequestMapping(value = "fg/webLogin.html", method = RequestMethod.POST, produces = "text/html; charset=utf-8")
    public String userLogin(String accountName, String password, HttpServletRequest request) {
        UsernamePasswordToken token = null;
        try {
            // 想要得到Subject对象,访问地址必须在shiro的拦截地址内,不然会报空指针
            Subject subject = SecurityUtils.getSubject();
            token = new UsernamePasswordToken(accountName, password);
            subject.login(token);
            if (subject.isAuthenticated()) {
                LoginInfoEntity loginInfo = new LoginInfoEntity();
                Session session = SecurityUtils.getSubject().getSession();
                loginInfo.setUserId(Integer.valueOf(session.getAttribute("userSessionId").toString()));
                loginInfo.setAccountName(accountName);
                loginInfo.setLoginIp(session.getHost());
                loginInfoService.insert(loginInfo);
                request.removeAttribute("error");

                // 获取登录的bean
               request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
                UserEntity userEntity = (UserEntity) request.getSession().getAttribute("userSession");

            }

在登录页面拿到登录的信息放到userSession中           页面可以直接点

<div class="top_wrap">
    <div class="top">
      <div class="top_left"> 您好,欢迎来到湖里创享在线！
        <c:if test="${empty userSession}">
        <span>请<a href="${ctx }/fg/login.html" title="" class="login">登录</a><a href="${ctx}/fg/personRegister.html" title="" class="mfzc">[免费注册]</a></span> </div>
      </c:if>
      <c:if test="${!empty userSession}">
      <span>账户名：<a href="${ctx }/ps/person/center.html" title="" class="login">${userSession.accountName}</a><em>|</em><a href="${ctx}/fg/logout.html" title="" class="mfzc">退出</a></span> </div>
    </c:if>
    <div class="top_right">0592-5778393</div>
  </div>

这样网页面的所有登录的都是有值得
