本文探讨了SSH2结合JPA时出现的事务提交失败问题，具体表现为TransactionSystemException异常，深入分析了其背后的RollbackException及ObjectDeletedException，并提供了相应的解决思路。
SSH2+JPA，提示如下错误：
Stacktraces
org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Error while commiting the transaction
javax.persistence.RollbackException: Error while commiting the transaction
org.hibernate.ObjectDeletedException: deleted entity passed to persist: [com.myfw.qx.model.QxUserRole#]
