CXF在视图模式中打开会话

Question

我有几个REST Web服务，我正在使用CXF Servlet公开。但是我遇到了一个类需要一个懒惰加载的集合（多个列表）的问题。我明白了：

Caused by: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: my.Model.lists, could not initialize proxy - no Session

我的cxf配置非常简单：

    <jaxrs:server address="/v2" id="connectionService">
        <jaxrs:serviceBeans>
            <ref bean="testService" />
            <ref bean="modelServicesLogic" />
        </jaxrs:serviceBeans>
        <jaxrs:providers>
            <ref bean="myLoggingFilter"/>
            <ref bean="jacksonProvider"/>
            <ref bean="myExceptionHandler" />

        </jaxrs:providers>
    </jaxrs:server>

如何实现“在视图中打开会话”模式，以便在Jackson序列化对象时我的hibernate会话可用？
