如何在Spring WebFlow2中将新模型传递给视图状态。我有一个输入屏幕,我的用户输入一些数据,然后它返回服务器进行处理。如果数据没问题,那么我必须设置一个Ticket Model并将其传递给下一个要显示的视图状态。
我无法获得下一个视图状态来显示故障单中的数据。有人可以帮帮我。
我的流程:
<view-state id="MemberInquiry" view="question.jsp" model="memberrequest" >
<transition on="submit" to="endState">
<evaluate expression="flowActions.addInquiry(memberrequest)" result="flowScope.ticket"/>
</transition>
<transition on="cancel" to="endState" bind="false"/>
</view-state>
<view-state id="endState" view="thanks.jsp" >
</view-state>
以下是控制器中的代码:
public Ticket addInquiry(MemberRequest memberrequest) {
LOGGER.debug("[" + memberrequest.toString() + "]");
// Setting data over to RT
String Ticket = memberInquiryService.sentWebRequest(memberrequest);
/*
* Setting out the ticket number to be displayed to user
*/
Map<String, Object> model = new HashMap<String, Object>();
Ticket t = new Ticket();
t.setTicketDetails(Ticket);
LOGGER.debug("[" + t.toString() + "]");
return t;
}
以下是感谢页面中的代码:

尝试动作状态:
<transition on="submit" to="addInquiry" />
<action-state id="addInquiry">
<evaluate expression="flowActions.addInquiry(memberrequest)" result="flowScope.ticket"/>
<transition to="endState" />
</action-state>
