Question

有没有办法在支持bean中获取导航案例的<to-view-id>？

我想说我想从结果<to-view-id>获得success，这应该是page1.xhtml。有辅助功能吗？

<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>

如果有帮助，我会使用PrettyFaces。

您可以从NavigationCase获得ConfigurableNavigationHandler。 NavigationCase表示已配置的导航案例，您可以从此对象获取所需的所有信息。观察：

 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>

以结果</to-view-id>从faces-config.xml以编程方式获取导航大小写<to-view-id>
