Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1

今天在使用Hibernate的时候，碰到这样一个异常：

Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1

详细异常信息如下：

发现异常：

org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count:

0; expected: 1

我用的是mysql数据库。

因为我在java中保存对象时采用了指定key的方式，而数据库中采用了autoinc。。

所以这里应该把autoinc去掉。并把相应的hbm.xml中的key指定方式修改为：assigned而非原先的identity。。。。
