Answer 1

这就是出错的第一句
[ERROR] Unimplemented function JVM_IHashCode called
百度里叶找不到啊

Answer 2

Unimplemented function JVM_IHashCode called
JVM_IHashCode应该是个接口，然后没有实现，却调用了

Answer 3

这个是虚礼机的问题，不允许同时开2太虚礼机，tomcat开了2个可能一个是自带个可能还有一个是你新安装的，重启肯定会解决的，本地的虚拟机还没关过，不知道在什么地方，你安装的可以关闭，不过关闭好像不行，重启吧，重启可以的

Answer 4

貌似jpa和hibernate要覆盖hashcode方法的，不怎么清楚
