异常原因

这里核心的异常就是hibernateNotObjectFound这个异常，大家都知道hibernate表关联引用有one-to-many/many-to-one等关联关系，这个异常解释为，多方对象中没有找到一方的关联引用，导致NotFoundObject异常

异常出现场景

大多数出现的场景是因为删除了一方的对象，而多方中的关联外键并没有清空导致的

解决办法

1.如果是配置文件：
在hibernate多方配置文件中，找到具体的外键引用对象 many-to-one 标签中加入: not-found=“ignore” 代码即可解决。

2.如果是注解：
在关联对象上添加注解：@NotFound(action=NotFoundAction.IGNORE) 即可。
