org.hibernate.LazyInitializationException: failed to lazily initialize a col

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.cmis.model.CFIS_Album.CFIS_Photos, org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.cmis.model.CFIS_Album.CFIS_Photos, no session or session was closed

这个是懒加载异常，就是在查询时没有加载关联表的对象，你读取这个关联对象的时候，hibernate的session已经关闭，所以无法获取对象。
可以在配置文件里关闭懒加载 lazily=false

如：
lazy="false">
