JSF2和x2B；Spring3和hibernate:Spring托管Bean（@Scope value="；view"；）LazyInitializationException异常

我已经使用找到的代码创建了自定义spring作用域，它支持使用与JSF2@ViewScoped类似的

view

作用域spring托管bean

当用户按下提交按钮时，会发生以下情况：

- Backbean AA (@Scope(value="view") calls injected @Service BB
- @Service BB calls DAO class CC 
- CC is @Transactional(readOnly = true) and has sessionFactory injected 
     private SessionFactory sessionFactory;

    //inject sessionGactory
    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
- in CC i set the @Transactional(readOnly = false, propagation = Propagation.REQUIRED)
  for functions such as save/delete/saveOrUpdate

与此类相关的Hibernate映射为：

RegUser.hbm.xml 如果我将bean范围设置为

@scope（value='request'）

我尝试将以下内容添加到

web.xml

中，但没有任何帮助：

<filter>
    <filter-name>openSessionInViewFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>openSessionInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

openSessionInViewFilter
org.springframework.orm.hibernate4.support.OpenSessionInViewFilter
openSessionInViewFilter
/*

我还尝试添加了

，但也没有效果

有人能指出我做错了什么以及我如何解决这个问题吗？

在这里找到了解决方案：

我需要补充一点

<f:attribute name="collectionType" value="java.util.HashSet" />
