JSF整合Spring时各文件的配置

最近在做一个需要JSF和Spring整合的项目，之前不知道如何在后台管理Bean获取被Spring管理的业务类对象，现在解决了，可以跑起来了！

1. web.xml
   
    1 <?xml version="1.0"?>
    2 <web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    3   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    4   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
    5     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    6   version="2.4">
    7  
    8   <display-name>example</display-name>
    9 
   10     <context-param>    
   11         <param-name>contextConfigLocation</param-name>
   12         <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
   13     </context-param>
   14 
   15     <listener>
   16       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
   17     </listener>
   18 
   19     <servlet>
   20         <display-name>FacesServlet</display-name>
   21         <servlet-name>FacesServlet</servlet-name>
   22         <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
   23         <load-on-startup>0</load-on-startup>
   24     </servlet>
   25 
   26     <servlet-mapping>
   27       <servlet-name>FacesServlet</servlet-name>
   28       <url-pattern>*.faces</url-pattern>
   29     </servlet-mapping>
   30      
   31 </web-app>
   
   
2. faces-config.xml
   
    1 <?xml version='1.0' encoding='UTF-8'?>
    2 <!DOCTYPE faces-config PUBLIC
    3 "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
    4 "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
    5 <faces-config>
    6     <application>
    7         <variable-resolver>
    8             org.springframework.web.jsf.DelegatingVariableResolver
    9         </variable-resolver>
   10     </application>
   
   12 <managed-bean>
   13   <managed-bean-name>infoBean</managed-bean-name>
   14   <managed-bean-class>
   15       com.jam.managedbeans.InfoBean
   16   </managed-bean-class> 
   17   <managed-bean-scope>request</managed-bean-scope>
   18 </managed-bean>
   19 
   20 </faces-config>
   
   
   
3. InfoBean.java
   假如InfoBean中需要使用业务类UserService的方法，而UserService交由Spring管理(id="userService")，InfoBean可以这样写：
   
   package com.jam.managedbeans;
   
   import java.util.Map;
   
   import javax.faces.context.ExternalContext;
   import javax.faces.context.FacesContext;
   
   import org.springframework.context.ApplicationContext;
   import org.springframework.web.jsf.FacesContextUtils;
   
   import com.jam.hibeinate.po.Bloguser;
   import com.jam.service.UserService;
   
   /**
    * @author Jam Chan
    * 
    */
   public final class InfoBean extends Object {
   
       /**
        * 用户名
        */
       private String userName;
       /**
        * 业务类
        */
       private UserService userService;
       /**
        * 密码
        */
       private String password;
   
       /**
        * 登陆验证
        * 
        * @return
        */
       public String loginValidate() {
           FacesContext facesContext = FacesContext.getCurrentInstance();
           ExternalContext extnContext = facesContext.getExternalContext();
           // POJO类
           Bloguser objUser = new Bloguser();
           objUser.setUsername(getUserName());
           objUser.setPassword(getPassword1());
           // 从Spring中获取需要的业务类UserService，我就是在这里被卡住，终于OK了
           ApplicationContext appContext = FacesContextUtils.getWebApplicationContext(facesContext);
           userService = (UserService) appContext.getBean("userService");
           // 验证用户
           boolean result = userService.loginValidate(objUser);
           // 获取SessionMap
           Map sessionMap = extnContext.getSessionMap();
           if (result) { // 登陆成功
               /* 把用户名设置在Session中 */
               sessionMap.put("userName", getUserName());
               return "success";
           } else { // 登录失败
               /* 清空session */
               if (sessionMap.containsKey("userName")) {
                   sessionMap.remove("userName");
               }
               return "failed";
           }
       }
       // setter getter省略
   
   暂时写到这，可能还要查漏补缺，发现问题继续加上！
