再三排查web.xml 和 faces-config.xml的配置都没错，最后发现是jsp页面少了 <f:view> 标签。

jsp 代码如下：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"pageEncoding="ISO-8859-1"%><%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%><%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title> Autotest here</title></head><body>hello<f:view><h:form id="form1"> <h:inputText value="input"/>  <h:outputText value="h:output"/> hello！ </h:form>></f:view><% out.println("name:--------------"); %></body></html>

浏览器输入：http://localhost:8080/autotest/index1.jsp  则报错，输入http://localhost:8080/autotest/index1.jsf 则页面能正常展示

web.xml 文件不能配有这段代码，否则输入http://localhost:8080/autotest/index1.jsf页面报错

<servlet-mapping><servlet-name>FacesServlet</servlet-name><url-pattern>*.jsp</url-pattern></servlet-mapping>

报错异常为：
