我有以下配置。

<!--

然后,当我运行带有insert语句的测试时,它们会产生错误消息:
javax.persistence.TransactionRequiredException: Executing an update/delete query
at org.hibernate.ejb.QueryImpl.executeUpdate(QueryImpl.java:47)
经过深思熟虑后,我尝试了这个:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:services.xml" })
@Transactional(propagation = Propagation.REQUIRED)
@TransactionConfiguration(defaultRollback = true)
@TestExecutionListeners(value = { DependencyInjectionTestExecutionListener.class, TransactionalTestExecutionListener.class})
public class SimpleUnitTest {
@Test
public void simpleTest() throws Exception {
System.out.println(entityManager.getTransaction().isActive());
assertTrue(entityManager.getTransaction().isActive());
}
}
它失败了。 entityManager.getTransaction()。isActive()实际上是假的。
为什么Transactional测试不会开始交易?
答案 0 :(得分:4)
您需要添加
@TestExecutionListeners(TransactionalTestExecutionListener.class)
或从
延伸AbstractTransactionalJUnit4SpringContextTests
获取交易行为。 (请记住,您的测试类不是bean,因此常规事务配置不适用)
答案 1 :(得分:0)
如果您使用TransactionalTestExecutionListener
,则默认启用SpringJUnit4ClassRunner
。
您需要确保在测试上下文配置中包含事务管理配置:
@ContextConfiguration(locations = { "classpath:services.xml" })
所以你可以通过注入TM bean来检查它:
@Autowired
private PlatformTransactionManager transactionManager;
如果未解决依赖关系,则说明事务配置未正确定位。
在调试测试期间,请检查堆栈跟踪中的TransactionInterceptor
。
答案 2 :(得分:0)
因为您有两个与配置相关的答案,我认为问题不在于配置,而在于您如何检查事务是否处于活动状态,以及如何获取EntityManager
实例。
可能存在的问题是:使用EntityManagerFactory.createEntityManager()
方法而不是注入EntityManager
。
