问题描述
我有以下配置。

指示Spring自动执行带注释的类的
声明式事务管理。 transaction-manager =transactionManager
- >
< tx：注解驱动的事务管理器=transactionManager/>
< / beans>
然后，当我运行带有insert语句的测试时，它们产生如下错误消息： p>
javax.persistence.TransactionRequiredException：执行更新/删除查询
at org.hibernate.ejb.QueryImpl.executeUpdate（QueryImpl .java：47）
经过深思熟虑之后，我试过了这个：
@RunWith（SpringJUnit4ClassRunner.class）
@ContextConfiguration（locations = {classpath：services.xml}）
@Transactional = Propagation.REQUIRED）
@TransactionConfiguration（defaultRollback = true）
@TestExecutionListeners（value = {DependencyInjectionTestExecutionListener.class，TransactionalTestExecutionListener.class}）
public class SimpleUnitTest {
@Test
public void simpleTest（）抛出异常{
System.out.println（entityManager.getTransaction（）。isActive（））;
assertTrue（entityManager.getTransaction（）。isActive（））;
}
}
失败。 entityManager.getTransaction（）。isActive（）实际上是false。
为什么交易测试不会开始交易？
@TestExecutionListeners（TransactionalTestExecutionListener。类）
或从
扩展<$ p $以获取事务行为。为了获得事务性行为，可以使用
AbstractTransactionalJUnit4SpringContextTests
（请记住，您的测试类不是一个bean，因此常规的事务配置不适用）
I have following configuration.

</bean>
<!--

on annotated classes. transaction-manager="transactionManager"
-->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
Then, when I ran tests that had an insert statement, they produced error messages as such:
javax.persistence.TransactionRequiredException: Executing an update/delete query
at org.hibernate.ejb.QueryImpl.executeUpdate(QueryImpl.java:47)
After much deliberation, I tried this:
@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());
}
}
And it failed. entityManager.getTransaction().isActive() was in fact false.
Why wouldn't Transactional test does not begin a transaction?
解决方案
You need to either add
@TestExecutionListeners(TransactionalTestExecutionListener.class)
or extend from
AbstractTransactionalJUnit4SpringContextTests
to get transactional behavior. (remember, your test class is not a bean, so regular transaction configuration does not apply)
