我正在尝试将我的应用程序从 jsf 1.2 迁移到 2.1。我写了一个示例 facelet 页面并尝试访问它。得到以下异常。不知道是什么导致了这个问题。如果仅执行此页面（通过删除与我的项目相关的所有代码和库，此页面将正确呈现）。关于可能导致此问题的任何帮助都会非常有帮助。

此问题与 faces-config.xml 有关。标题应该是。

<faces-config version="2.0"
   xmlns="http://java.sun.com/xml/ns/javaee"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
      http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">

在你的 head 元素中包含这个标签，如下所示：

<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</h:head>
