Could not commit JPA transaction; nested exception is javax.persistence.RollbackException 解决方法

Could not commit JPA transaction; nested exception is javax.persistence.RollbackException

原因:同一service方法里多次save导致,save过一次,事务已经提交了,如果再次save,则事务已经变为回滚状态,已经不能再次提交事务了。

可能没说清楚:如果在save一个表时,同时关联到的外键表也去save,会报这个异常。
