    跟spring和hibernate都没关系。仔细阅读错误。这都需要伸手了么.

    可是我的User是存在的也配置进去了，错在哪里了呢？

    用惯了注解+springjpa，一下看到这个还真看不懂了

    不用注解吗？

    都Spring4的年代了还要用hbm.xml，看哭我了。话说我还真没看到啥错误，猜测应该还是配置问题吧。要不试试将model类换成注解方式？

    没有扫描到你的实体类，应该是mappingDirectoryLocations配置问题，hibernate用的xml还是注解？xml，但是我用上面的fun1测试是没有问题的，mappingDirectoryLocstions配置就在上面有什么问题呢？
