tomcat集群时候，报org.hibernate.LazyInitializationException

Question

如题，项目在单一服务器上运行的时候没有问题，但是做了tomcat集群之后，出现异常：如下
org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: cn.eshore.eip.platform.persistence.entity.user.User.userBindInfos, no session or session was closed
at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:383)
at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:375)
at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:122)
at org.hibernate.collection.PersistentBag.size(PersistentBag.java:248)
at de.javakaffee.web.msm.serializer.javolution.ReflectionBinding$XMLCollectionFormat.write(ReflectionBinding.java:381)

在网上搜过之后，大部分回答是说因为HIbernate一对多关系的 一 方 使用懒加载，使得需要访问懒加载的数据时候session关闭的原因，但是我按那个方法试了没有用，希望有这方面经验的大神知道一下，小弟没有积分，所以只能按最低分数悬赏了

    at de.javakaffee.web.msm.serializer.javolution.ReflectionBinding$XMLCollectionFormat.write(ReflectionBinding.java:381)  从这段代码可以看到你得到的数据是反序列化回来的

如果你的对象有lazy 的collection 解决办法可以考虑改成非lazy的
