以编程方式从faces-config.xml按结果获取导航大小写<to-view-id>

Question

有没有办法<to-view-id>在支持bean中获得导航案例？

让我们说我想<to-view-id>从结果中得到结果success,这应该是page1.xhtml.有没有帮手功能？

<navigation-rule>
    <from-view-id>start.xhtml</from-view-id>
    <navigation-case>
        <from-action>#{pageController.processPage1}</from-action>
        <from-outcome>success</from-outcome>
        <to-view-id>page1.xhtml</to-view-id>
    </navigation-case>
    <navigation-case>
        <from-action>#{pageController.processPage2}</from-action>
        <from-outcome>success</from-outcome>
        <to-view-id>page2.xhtml</to-view-id>
    </navigation-case>
</navigation-rule>  

如果它有帮助,我正在使用PrettyFaces.

你可以NavigationCase从a 获得一个ConfigurableNavigationHandler.该NavigationCase代表配置的导航的情况下,你可以让你从这个对象需要的所有信息.注意:

 ConfigurableNavigationHandler configNavHandler = (ConfigurableNavigationHandler)ctxt.getApplication().getNavigationHandler(); //assumes you already have an instance of FacesContext, named ctxt
 NavigationCase navCase = configNavHandler.getNavigationCase(ctxt,null,"success");

 String toViewId = navCase.getToViewId(ctx); // the <to-view-id>
