jsf - 为什么我不能使用返回值“成功”从 managedBean 导航到另一个页面？

Question

我正在使用 Eclipse 使用 JSF、Hibernate 和 Tomcat 服务器。我在一个名为“ListeAutoTPEs.jsp”的jsp页面中，当提交表单时，会调用一个方法（它从jrxml文件创建一个PDF）但无法访问我提到的页面“test2.htm”在“成功”的导航案例中的 tha faces-config

我的 faces-config.xml 页面：

我的 JSP 页面“ListeAutoTPEs.jsp”

 <h:commandButton value="télécharger" action="#{traitement.toutLesAuto}" >

导航规则提到 /listeTransacTelecol.jsp 作为来自 id。与 ListeAutoTPEs.jsp 不匹配。

我不确定是否允许转发到 html，我自己从未尝试过。

我想您不能转发到纯 HTML 文件。也许您可以将 test2.htm 更改为 JSP 页面并尝试：

<navigation-case>
    <from-outcome>success</from-outcome>
    <to-view-id>/test2.jsp</to-view-id>
    <redirect/>
</navigation-case>

所有其他导航规则是否按预期工作？
