JSF整合Spring时各文件的配置

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！
