关于Hibernate中调用集合类时出现的 the owning Session was closed 错误解决方案
错误异常：
08:42:43,546errorlazyinitializationexception:19-couldnotinitializeproxy-theowningsessionwasclosed
org.hibernate.lazyinitializationexception:couldnotinitializeproxy-theowningsessionwasclosed
atorg.hibernate.proxy.abstractlazyinitializer.initialize(abstractlazyinitializer.java:60)
atorg.hibernate.proxy.abstractlazyinitializer.getimplementation(abstractlazyinitializer.java:111)
atorg.hibernate.proxy.pojo.cglib.cgliblazyinitializer.invoke(cgliblazyinitializer.java:172)
解决方案：
hibernate默认是延迟加载，而导致无法将集合类中数据读取出来
则可以在相应pojo对应的hbm.xml文件里做出相关修改
1可以在hibernate-mapping标签中设置属性default-lazy="false"
2也可以在class标签中设置属性lazy="false"
以上都可以解决问题
