版本 struts2 1.1.8.1 spring 2.5.6 hibernate 3.6
烦！烦！烦！
看OA的教学视频 ， 首次使用三大框架结合，在hibernate save可以自动自动提交，但是delete,和update却不行，执行时没报错，但就是没修改数据库数据。使用了sping和hibernate都不知道从何入手，因为spring给你自动提交事务，给你创建session。最后session判断是打开的 但事务就不懂的怎么去看有没有提交了。纠结了好久，在看看老师的视频，也是一样的啊，那为啥他的可以，我的就不行呢。郁闷啊。又纠结了一会，百度一下，还真让我找到答案了，要在“session是个一级缓存，当你save的时候，不会存放在缓存中，直接添加到数据库！update和delete时，会先将session缓存的数据删除，然后提交到数据库，但是你这个时候已经将session关闭了！要加session.flush() ”。那为啥老师的没有更新缓存也可以呢，我也是无语了。花了我这么长的时间，该死
现在终于知道老师的为啥可以了， 原来是J2EE的版本不同。 j2EE的版本是5.0可以不用session.flush()也可以更新，但是如果是6.0的就不可以了，而且如果用6.0的版本时，当一开始测试SessionFactory时还会报下面错误。必须还要在hibernate.cfg.xml中加上<property name="javax.persistence.validation.mode">none</property>。同时发布后操作数据库超过13次后就卡在那，不报错，也不抛异常。
