Javassist Enhancement failed

四月 16, 2015 10:48:07 上午 org.hibernate.event.internal.DefaultLoadEventListener onLoad

INFO: HHH000327: Error performing load command : org.hibernate.HibernateException: Javassist Enhancement failed: com.spri.entity.User

报错原因是在User当中显示的写了一个构造方法，把原来默认的构造方法给覆盖了。这里用到了hibernate的持久化，那么为什么它的持久化需要一个无参的构造方法呢，原因是Hibernate的实现持久化的机制是反射，它在反射的时候,需要调用newInstance()，这个方法就是通过调用默认构造方法来创建实例对象的。在本例中自己写了一个有参的构造方法，把原来默认的构造方法覆盖了，而原来默认的方法是无参的，所以需要再显示构造一个无参数的构造方法。

解决办法：在User当中添加一个无参的构造方法。
