Question

我的JSF 2项目结构如下：

root
...
   WebContent
      META-INF
      resources
         css
         images
         javascript
   templates
      commonLayout.xhtml
      footer.xhtml
      header.xhtml  
   views
      main
         index.xhtml
   WEB-INF
   index.jsp

当我尝试在http://localhost/home/main/index.jsf处查看我的页面时遇到此错误：

index.xhtml的内容是：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">

<ui:composition template="templates/commonLayout.xhtml">
    <ui:define name="header">
        Add your header here or delete to use the default
    </ui:define>
    <ui:define name="content">
        Add your content here or delete to use the default
    </ui:define>
    <ui:define name="footer">
        Add your footer here or delete to use the default
    </ui:define>
</ui:composition>
</html>

过去两天我一直坚持这个问题。任何人都可以看到问题是什么？我根本不知道

两件事：

首先，您的项目结构不正确。所有Web文件都必须进入WebContent。

root
...
   WebContent
      META-INF
      resources
         css
         images
         javascript
      templates
         commonLayout.xhtml
         footer.xhtml
         header.xhtml  
      views
         main
            index.xhtml
      WEB-INF
      index.jsp

然而，这会产生404错误而不是此异常。所以我会假设在制定问题时你只是粗心大意。

其次，如果template中的ui:composition路径以/开头，则它相对于WebContent。但如果它不以/开头，那么它与当前文件相关。正如您目前所拥有的，Facelets将尝试从/views/main/templates/commonLayout.xhtml加载模板，这确实是错误的。因此，请按照以下步骤修复template路径：

<ui:composition template="/templates/commonLayout.xhtml">

JSF2和Facelets - java.io.FileNotFoundException
