Entity关系是这样的： 一个Student 一对一关联CmsMember，Cmsber关联 Member，Member关联User。 我在action里通过业务逻辑层获取Student的List，然后在显示层展示user List的realName时报如下错误。但是我在后台继承自JeeCoreAction用同样业务逻辑的代码，却不会报错。 我们已经采用了osiv的机制，为什么会有LIE错误，是我哪里设置得不对还是怎么？ 这个问题已经困扰我4天多了，在这段时间我看了很多网上的解答，都没有找到相关解决方案，急切盼望解答，谢谢。 我所用的jeecms版本是2.4。  ERROR o.h.LazyInitializationException - could not initialize proxy - no Session

所有这个Action里的 所有 lazy="true“的entity都会报这个错误。

这个。。。涉及到编写代码的不在技术支持范围之内

能请技术人员帮忙看一下吗？真的困扰太久了。
只要我们的域名批了下来，一定购买授权的，但是这个问题困扰使产品一直无法交付给客户。

您可以购买我们的二次开发技术支持，我们有专门的技术人员给您提供技术支持。版主是负责回复系统安装使用方面的问题的。

我把log置到debug级别的时候发现问题所在了。
不是因为hibernate session关闭引起的，而是之前有一个通过hibernate提交访问产生了异常，导致后面hibbernate报了这样一个LIE错误，把之前的一场解决之后就没有LIE异常了。
我把log置到debug级别对于bug跟踪果然有帮助。
