我的交易有点问题。我将 Spring 3.1.1.RELEASE、Spring Data 1.0.3.RELEASE JPA 与 Hibernate 提供程序一起使用。当我开始一个 junit 测试时,在哪里用@Transactional
它注释的方法似乎很好,但是当我启动整个应用程序时,没有错误,但事务不起作用。这是我的配置和示例代码:
应用程序上下文.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>
持久性.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>
用户存储库.java
公共接口 UserRepository 扩展 CrudRepository<User, Long>{ }
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
}
}
用户服务测试.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 JUnit 测试的情况下,尽管服务方法使用@Transactional
. 当我将此注释添加到testUserAdd()
方法时,我会在控制台中得到它:
2012-05-17 11:17:54,208 INFO [org.springframework.test.context.transaction.TransactionalTestExecutionListener] - Rolled back transaction after test execution for test context [[TestContext@23ae2a testClass = UserRepositoryTest, testInstance = com.sheedo.upload.repository.UserRepositoryTest@7f52c1, testMethod = testUserAdd@UserRepositoryTest, testException = java.lang.RuntimeException, mergedContextConfiguration = [MergedContextConfiguration@111fd28 testClass = UserRepositoryTest, locations = '{classpath:/META-INF/spring/root-context.xml}', classes = '{}', activeProfiles = '{}', contextLoader = 'org.springframework.test.context.support.DelegatingSmartContextLoader']]]
我想这是正确的。那么,注释怎么可能@Transactional
只在 Junit 测试类中有效,而在其他 spring bean 中无效呢?
我的理论是,它SpringJUnit4ClassRunner
以某种方式提供了这种交易。我的 Spring 配置中是否有问题,即事务在我的应用程序中不起作用,而仅在 Junit 测试类中起作用?appContext 中缺少什么?
