session的运用

 1。。

 final HttpServletRequest request = ServletActionContext.getRequest();
  HttpSession session = request.getSession();
  String verifyCode = (String) session.getAttribute("verifyCode");
  String clientVerifyCode = request.getParameter("verifyCode");

  if (session.getAttribute("verifyPic") != null) {
   if (!(StringUtils.hasText(verifyCode) && StringUtils.hasText(clientVerifyCode) && clientVerifyCode
     .equalsIgnoreCase(verifyCode))) {
    this.addActionError("验证码输入错误！");
    return "login";
   }
  }
  String k = PasswordHash.encrypt(this.getPassword());
  final CustomerAccess access = this.customerAccessService.login(username, k);
  if (access == null) {
   this.addActionError("登录失败,请重新登录!");
   session.setAttribute("verifyPic", "true");
   return LOGIN;
  }

对session中去到的verifycode运用完后，删除属性。

  session.removeAttribute("verifyPic");

2。。JSP页面中：

<%

 String path = request.getContextPath();
 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
 ActionContext.getContext().put("basePath",basePath);

 CustomerUserBean user = (CustomerUserBean) session.getAttribute("User");

  ActionContext.getContext().put("isAdmin",user.getUserRecord().getIsadmin());
%>

<s:property value="#basePath" />

<s:property value="#session.User.userRecord.unit.orgId" />

<s:property value="#isAdmin" />
