hibernate一对多关系映射报错： could not initialize proxy - no Session

当查询一的这边时，出现错误：could not initialize proxy - no Session。 我的操作是在一个事务里面，使用spring来管理事务，所以session应该不会提前关闭呀？？？

应该不是事务的问题呀！我只要不操作子表的数据，那父表的数据是可以正常显示出来的，我考虑可能是懒加载的问题，然后去配置@OneToMany(fetch=FetchType.EAGER)，可是还是不行。然后报了另外一个错误：HTTP Status 500 - Handler processing failed; nested exception is java.lang.StackOverflowError

一的这边配置

@Cascade(CascadeType.ALL)
@OneToMany
@JoinColumn(name="goodsUuid")
private Set<ReptileModel> reptileList = new HashSet<ReptileModel>();
多的这边配置
@ManyToOne
@JoinColumn(name="goodsUuid")
pivate GoodsModel goodsModel;
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.xiaoxing.shangjia.goods.vo.GoodsModel.reptileList, could not initialize proxy - no Session
