Error while commiting the transaction问题

标签：error while commiting the transaction   could not execute jdbc batch update   

在搭建一个spring3.0+hibernate+jpa项目框架，根据网友提供的例子，在junit下做了一个存储数据的测试，报如下异常：

网上搜索了一阵，没什么收获。还是自己解决吧。逐层分析异常堆栈如下：

Caused by: java.sql.BatchUpdateException: Table ‘j2ee.student‘ doesn‘t exist；   Caused by: org.hibernate.exception.SQLGrammarException: Could not execute JDBC batch update；

Caused by: javax.persistence.RollbackException: Error while commiting the transaction；

猜测问题的原因可能是因为：insert一条记录，正常情况下，如果表不存在，则会创建表，然后insert记录。这里因为是junit环境，且表不存在，在一个“事务”环境中，要建表、insert记录，因为什么原因，建表失败。导致Insert失败。

为了验证这个测试，手动建表，然后执行该junit测试操作，insert成功；

删除表，在正常环境下启动web服务器，成功启动后表即被建立，然后对该表的操作都成功。

到这里，初步得出一个结论，jap+hibernate+spring环境，建表同对表的操作不宜在一个“事务”中完成；

以上分析还未找到理论上的答案...
