注：Spring的applicationContext.xml事务代理管理的配置省略……

之前我实现多表查询的时候抛出
could not initialize proxy - the owning Session was closed
org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed
……………………
的异常，如果想使Session is opened需要在web.xml添加如下配置：
     <filter>
        <filter-name>openSessionInViewFilter</filter-name>
        <filter-class>
            org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
        </filter-class>
    </filter>
    <!-- 选择需要过滤的页面 -->
    <filter-mapping>
        <filter-name>openSessionInViewFilter</filter-name>
        <url-pattern>*.faces</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>openSessionInViewFilter</filter-name>
        <url-pattern>*.do</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>openSessionInViewFilter</filter-name>
        <url-pattern>*.jsp</url-pattern>
    </filter-mapping>

之后就OK啦~！！哈哈

    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：

    import javax.faces.context.ExternalContext;
    import javax.faces.context.FacesContext;

    import org.springframework.context.ApplicationContext;

    import com.jam.service.UserService;

    /**

    public final class InfoBean extends Object {

            /**

             */
            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！

原因：
找不到 Caused by: java.lang.NoClassDefFoundError: org/apache/commons/pool/impl/GenericObjectPool
就Apache所提供的基本对象池。

解决：
到这里http://commons.apache.org/downloads/download_pool.cgi下载包，然后,把里面的commons-pool-x.jar复制到myEclipse的Referenced Libraries下.

2、加入spring2.0的支持
加入的包有：
            Spring2.0 AOP Libraries(对aop的支持)
            Spring2.0 Core Libraries
            Spring2.0 Persistence Core Libraries
            Spring2.0 Persistence JDBC Libraries(JDBC支持)
            Spring2.0 Testing Suppor Libraries
            Spring2.0 Web Libraries
            Hibernate3.2 Core Libraries
            Hibernate3.2 Annotations & Entity Manager
            Hibernate3.2 Advanced Support Libraries
3、加入hibernate 选择myEclipse Libraries 但是不选择任务包
4、配置struts-config.xml文件
<!-- 控制器 -->
    <controller  processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />
    <!-- struts,spring集成插件 -->
    <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
        <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
    </plug-in>

5、加入包commons-pool.jar spring.jar
6、删除包asm-2.2.3.jar hibernate-annotaions.jar
