java接口，避開登陸方法-

    @Override
    public String intercept(ActionInvocation invocation) throws Exception {
        ActionContext actionContext = invocation.getInvocationContext();     
        Map<String,Object> session = actionContext.getSession();
        HttpServletRequest request= (HttpServletRequest) actionContext.get(StrutsStatics.HTTP_REQUEST);
        String methodName = invocation.getProxy().getMethod();
        String actionName = actionContext.getName();
        UserVo userVo=(UserVo)session.get("userVo");
        //若是是登陸面，不檢查session
        if((actionName.equals("userAjax") && methodName.equals("login")) 
                || (actionName.equals("danweiAjax") && methodName.equals("getDanWeiList")) 
                || (actionName.equals("userAjax") && methodName.equals("checkUserExist"))
                || (actionName.equals("userAjax") && methodName.equals("checkUserExist_ganbuzhuce"))
                || (actionName.equals("userAjax") && methodName.equals("loadMessage"))
               || (actionName.equals("danweiAjax") && methodName.equals("addGanbuzhuce")) 
                ){
            return invocation.invoke();
        }
        
        if(userVo==null){
            request.setAttribute("errorMessage", "登陸超時，請從新登陸!");
            return "error";
        }else{
