网上查出的是：出现异常的原因是少了ejb3-persistence.jar这个jar包
添加后出现：
java.lang.NoClassDefFoundError: javax/persistence/Cacheable

网上又说：出现异常的原因是少了ejb3-persistence.jar和jpa冲突，需要删除ejb3这个jar包，到底咋回事啊

Answer 1

我遇到过这个问题，你的包要一个一个导，我记得hibernate，spring，和struts框架里面有一个会冲突。。当时好像把这三类包分开导入就好了。。你试试吧、

Answer 2

就是冲突了。

Answer 3

应该是版本冲突了

Answer 4

应该是缺少相应的jar包
