I am a beginner in both hibernate and spring. I have understood about the hibernate transaction demarcation (at least I think so). But after coding a few method like this:
sessionFactory.getCurrentSession().beginTransaction();
//do something here
sessionFactory.getCurrentSession().endTransaction();
I started to want to avoid it and want to have it automatically done outside my method such that I only write the "//do something here" part. I have read about the TransactionProxyFactoryBean and think that the xml configuration is very long and have to be repeated for EVERY classes I want to make transactional so if possible I want to avoid using it.
I tried to use the @Transactional but it doesn't work at all. I have these lines in my applicationContext.xml
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
and I have already marked my service classes with @Transactional but I always get the "xxx is not valid without active transaction". Here is an example code that give me an error (run in unit test btw):
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations =
{
"classpath:applicationContext.xml"
})
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
public class UserServiceTest
{
@Resource
private UserService userService;
@Test
public void testAddUser()
{
User us = new User();
us.setName("any name");
userService.addUser(us);
}
}
In this case, the exact error message is: "org.hibernate.HibernateException: save is not valid without active transaction".
UPDATE: I tried calling the userService.addUser() method from outside unit tests (i.e. from actual web application) and I got the same error as well.
This is my hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Enable Hibernate's automatic session context management -->
<property name="current_session_context_class">thread</property>

<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">update</property>
<!-- all my mapping resources here -->
</session-factory>
</hibernate-configuration>
The userService class is marked with @Transactional. I am using hibernate 3.3.2 and spring 2.5.6.
Can I have some advice on how to fix this?
