I have a little problem with transactions. I use Spring 3.1.1.RELEASE, Spring Data 1.0.3.RELEASE JPA with Hibernate provider. When I start a junit test where is a method annotated with @Transactional it seems fine but when I start a whole application there are no errors but transactions don't work.
Here's my configurations and sample code:
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>
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
public interface UserRepository extends 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
}
}
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");
}
}
In this case of JUnit test, transaction doesn't work event though the service method is annotated with @Transactional. When I add this annotation to testUserAdd() method I get this in console:
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']]]
which is correct I suppose. So, how can be possible that @Transactional annotation works only in Junit test class, but not in others spring beans ?
My theory is that SpringJUnit4ClassRunner somehow provides this transaction. Have I something wrong in my spring configuration that transactions don't work in my app but only in Junit test classes? Something missing in appContext?
Edit: log:
