Question

我试图对一些持久性代码进行单元测试，并且我遇到了数据库挂起到以前测试中创建的行的问题。我也在使用Hibernate Search，尽管这并没有反映在我在这里分享的代码中。

我使用的是Spring 3.1.x，Hibernate 4.x和HSQLDB 2.3.2

Answer 1

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

Answer 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>

Answer 3

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

Answer 4

所以，我终于通过在BoneCPDatasource上指定defaultAutoCommit = false来实现这一点。 AFAIK对于这种配置来说太低了，因此可能是错误的。但至少它正在发挥作用。

Junit测试在交易后没有回滚
