（1）：查看 和修改 ui'view 目录 WEB-INF\cas.properties
cas.viewResolver.basename=default_v1_views
（2）：创建 错误信息提示页面 WEB-INF/view/jsp/default_v1/ui/casMobileLoginErrorView.jsp
内容如下：
<%@ page contentType="application/json; charset=UTF-8"%>
{"code":"1","msg":"用户信息输入有误"}
casMobileLoginErrorView.(class)=org.springframework.web.servlet.view.JstlView casMobileLoginErrorView.url=/WEB-INF/view/jsp/default_v1/ui/casMobileLoginErrorView.jsp
（4）：修改 条件判断代码unkNow/cas/server/web/AjaxLoginServiceTicketAction
@Override
protected Event doExecute(final RequestContext context) {
HttpServletRequest request = WebUtils.getHttpServletRequest(context);
Enumeration enu=request.getParameterNames();
while(enu.hasMoreElements()){
String paraName=(String)enu.nextElement();
System.out.println(paraName+": "+request.getParameter(paraName));
}
Event event = context.getCurrentEvent();
boolean isAjax = BooleanUtils.toBoolean(request.getParameter(BasicPropertiesReader.getInstance().getAjaxMark()));
boolean ismobile=BooleanUtils.toBoolean(request.getParameter("ismobile"));
System.out.println("AjaxLoginServiceTicketAction event:"+event);
System.out.println("AjaxLoginServiceTicketAction username:"+request.getParameter("_eventId"));
System.out.println("AjaxLoginServiceTicketAction isAjax:"+isAjax);
System.out.println("AjaxLoginServiceTicketAction isAjax:"+BooleanUtils.toBoolean(request.getParameter("isajax")));
if (ismobile){
return new Event(this,"casMobileLoginError");
}
}
（5）： 修改WEB-INF\login-webflow.xml文件 ，修改如下：
下相应的Action-status 添加 如下内容：
<action-state id="loginResponse"> <evaluate expression="ajaxLoginServiceTicketAction" /> <!--非ajax/iframe方式登录，采取原流程处理 --> <transition on="success" to="warn" /> <transition on="casMobileLoginError" to="casMobileLoginErrorView" /> <transition on="error" to="viewLoginForm" /> <!-- 反之，则进入 viewAjaxLoginView 页面 --> <transition on="local" to="viewAjaxLoginView" /> </action-state>
添加view 页面ID
<end-state id="casMobileLoginErrorView" view="casMobileLoginErrorView" />
