我有一个交易小问题。我使用Spring 3.1.1.RELEASE，Spring Data 1.0.3.RELEASE JPA和Hibernate provider。当我开始JUnit测试其中一个方法标注了@Transactional似乎罚款，但是当我开始整个应用程序没有错误，但成交不工作。 这里是我的配置和示例代码：春天，JPA交易只能在JUnit测试而不是在应用
的applicationContext.xml
<context:annotation-config />
<context:component-scan base-package="com.sheedo.upload" />
<jpa:repositories base-package="com.sheedo.upload.repository" />
<tx:annotation-driven transaction-manager="transactionManager" />
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath*:messages/*.properties</value>
<value>classpath*:*.properties</value>
</list>
</property>
</bean>
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="persistenceUnit" />
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<bean id="dataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource">
<property name="url" value="${jdbc.url}" />
<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
的persistence.xml
<persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect" />
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy" />
<property name="hibernate.connection.charSet" value="UTF-8" />
<property name="hibernate.show_sql" value="true" />
</properties>
</persistence-unit>
UserRepository.java
公共interfa CE UserRepository扩展CrudRepository <用户，龙> {}
UserServiceImpl.java
@Service("userService")
public class UserServiceImpl implements UserService {
@Autowired
private UserRepository userRepository;
@Override
@Transactional
public void addUser(String name, String surname) {
User u = new User(name, surname);
userRepository.save(u);
throw new RuntimeException(); // to invoke a rollback
}
}
UserServiceTest.java
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:/META-INF/spring/root-context.xml" })
public class UserServiceTest {
Logger log = LoggerFactory.getLogger(getClass());
@Autowired
private UserService userService;
@Test
public void testUserAdd() {
userService.addUser("John", "Doe");
}
}
在这种情况下JUnit测试的，交易也不行事件虽然服务方法注释为@Transactional。当我这个注释添加到testUserAdd()方法我得到这个控制台：
2012-05-17 11:17:54,208 INFO [org.springframework.test.context.transaction.TransactionalTestExecutionListener] - Rolled back transaction after test execution for test context [[[email protected] testClass = UserRepositoryTest, testInstance = [email protected], testMethod = [email protected], testException = java.lang.RuntimeException, mergedContextConfiguration = [[email protected] testClass = UserRepositoryTest, locations = '{classpath:/META-INF/spring/root-context.xml}', classes = '{}', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader']]]
这是正确的，我想。那么，如何可能的是@Transactional注释只能在JUnit测试类，而不是在别人的Spring bean？
我的理论是SpringJUnit4ClassRunner某种程度上提供了本次交易。我的弹簧配置有问题，我的应用中的交易不起作用，但仅在Junit测试类中有效？ appContext中缺少的东西？

component-scan配置如何诊断的事务“不工作”？ –当我在UserService中调试这个事务性方法时，即使该方法完成了异常，它会在“userRepository.save（user）”之后将实体保存到数据库中。我没有登录控制台该交易开始。 –
启用“org.springframework.transaction”记录器。同样的。这将有助于进一步分析。 –
