3.faces-config.xml
<faces-config 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" version="2.0"> <navigation-rule><from-view-id>/index.jsp</from-view-id><navigation-case><from-outcome>login</from-outcome><to-view-id>/welcome.jsp</to-view-id></navigation-case></navigation-rule><!-- 使用了注解， 所以这里没有ManagedBean --></faces-config>

4. Bean文件? UserBean.java
import javax.faces.bean.ManagedBean;import javax.faces.bean.SessionScoped;@ManagedBean(name="user")@SessionScopedpublic class UserBean {private String name;private String password;public String getName() {return name;}public void setName(String newValue) {name = newValue;}public String getPassword() {return password;}public void setPassword(String newValue) {password = newValue;}}?

5. 测试jsp? index.jsp?? 访问时 是index.faces
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!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=UTF-8"> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <f:view> <head> <title>Index </title> </head> <body> <h:form> <h3>Please enter your name and password.</h3> <table> <tr> <td>Name:</td> <td> <h:inputText value="#{user.name}"/> </td> </tr> <tr> <td>Password:</td> <td> <h:inputSecret value="#{user.password}"/> </td> </tr> </table> <p> <h:commandButton value="Login" action="login"/> </p> </h:form> </body> </f:view></html>?
6.跳转成功的页面
<!-- welcome.jsp --><html> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %> <f:view> <head> <title> Welcome</title> </head> <body> <h:form> <h3> Welcome to JSF, <h:outputText value="#{user.name}"/>! </h3> </h:form> </body> </f:view></html>?
