JSF 2.0隐式导航，不同的视图 [英] JSF 2.0 implicit navigation, different views

问题描述

我正在寻找有关JSF 2.0隐式导航及其如何与视图一起使用的很好的解释.更准确地说，我了解从一种操作方法中，我可以返回一个字符串，该字符串是该操作的结果.如果存在一个JSF视图，其文件名与结果匹配，则这是隐式导航.

I'm looking for a good explanation to JSF 2.0 implicit navigation and how it works with views. To be more precise, I understand that from an action method I can return a string which is the outcome of the action. If there's a JSF view whose file name matches the outcome, then this is implicit navigation.

现在...我的问题是，如果从某个文件夹内的视图中调用该操作，但是要导航至下一个视图的视图位于另一个文件夹中，该怎么办?即，从/manager/edit.xhtml中调用一个动作.该操作应返回什么字符串，以便导航可以安全地转到/user/list.xhtml或/index.xhtml或/manager/index.xhtml?

Now... my question, what if the action is invoked from a view that's inside a folder but the view that I want to navigate to next is in a different folder? I.e., from /manager/edit.xhtml an action is invoked. What String should that action return so that navigation can safely go to /user/list.xhtml or to /index.xhtml or to /manager/index.xhtml?

推荐答案

据我所知，JSF仅在当前上下文中寻找匹配的视图.您可能必须在faces-config.xml中定义一个导航规则，以特殊方式处理结果.这是一个示例:

As far as my knowledge goes, JSF looks for a matching view only within the current context. You probably have to define a navigation rule in your faces-config.xml to handle an outcome in a special way. Here is an example:

<navigation-rule>
        <from-view-id>/profiles/viewkeypages.xhtml</from-view-id>
        <navigation-case>
            <from-outcome>editkeypage</from-outcome>
            <to-view-id>/users/editkeypage.xhtml</to-view-id>
            <redirect />
        </navigation-case>      
</navigation-rule>
