CXF 在视图中打开会话模式

Question

我使用CXF Servlet公开了一些REST服务。然而，我遇到了这样的问题:一个类需要一个延迟加载的集合(不止一个列表)。我得到了这个:

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配置相当简单:

    <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？
