【中文标题】Junit测试在事务后不回滚

【英文标题】：Junit test not rolling back after transaction

【发布时间】：2014-05-04 18:19:59

【问题描述】：

我正在尝试对一些持久性代码进行单元测试，但遇到了数据库挂在先前测试中创建的行上的问题。我也在使用 Hibernate Search，虽然这没有反映在我在这里分享的代码中。

我正在使用 Spring 3.1.x、Hibernate 4.x 和 HSQLDB 2.3.2

【问题讨论】：

尝试在您的测试中添加@Rollback(true) 注释。

谢谢。没有区别

可能是因为你没有清理你的数据？

我还尝试使用 rollback=true 显式指定事务管理。没有帮助，这是 Spring 设置的默认值。日志表明回滚实际上正在发生，它似乎没有传播到数据库

清理是什么意思？回滚表明不需要显式清理？

【参考方案1】：

尝试在测试类上添加@Transactional 注解。 http://docs.spring.io/spring/docs/2.0.x/api/org/springframework/transaction/annotation/Transactional.html

【讨论】：

是的，这没有帮助

【参考方案2】：

尝试添加事务拦截器：

<beans xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="
    ...
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

【讨论】：

这里有，我没有在示例中包含这个

【参考方案3】：

扩展 AbstractTransactionalJunit4SpringContextTests 或添加 @TestExecutionListeners(TransactionalTestExecutionListener.class)。

【讨论】：

不确定这是否会有所帮助，因为它只是一个方便类，用于似乎已经存在的东西

我以前遇到过一个问题，因为缺少@TestExecutionListeners(TransactionalTestExecutionListener.class)。

顺便说一下，你扩展了TestCase——你用的是什么版本的junit？ （在 Junit4 中不需要扩展任何东西）。

【参考方案4】：

所以，我终于通过在 BoneCPDatasource 上指定 defaultAutoCommit=false 来完成这项工作。 AFAIK 这对于这种配置来说太低了，因此可能是错误的。但至少它是有效的。
