java - CXF 在 View 模式中打开 session

Question

我有一些使用 CXF Servlet 公开的 REST Web 服务。然而，我遇到了一个类的问题，该类需要延迟加载的集合(多个列表)。我得到这个:

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 View 中打开 session ”模式，以便当 Jackson 序列化对象时我的 hibernate session 可用？
