Spring Hibernate MySQL Test doesn't roll back - mysql

Question

I have a problem with transactional tests using Spring 3.0.5, Hibernate 3 and MySQL 5.
In logs it seems there's everything OK and transaction rolls back, but I got record inserted into database.
My configuration is like this:
<bean id="hibernateDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/blog" />
<property name="username" value="user" />
<property name="password" value="password" />
<property name="defaultAutoCommit" value="false" />
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="hibernateSessionFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="hibernateDataSource" />
<property name="schemaUpdate" value="true" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.connection.autocommit">false</prop>
</props>
</property>
<property name="annotatedClasses">
<list>
<value>pl.jedenpies.blog.domain.Uzytkownik</value>
</list>
</property>
</bean>
<bean id="uzytkownikDao" class="pl.jedenpies.blog.db.hibernate.dao.HibernateUzytkownikDao">
<property name="sessionFactory" ref="hibernateSessionFactory" />
</bean>
Test class:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(locations = {"classpath:beans.xml"})
#TransactionConfiguration(defaultRollback = true)
public class UzytkownikDaoTest {
private UzytkownikDao uzytkownikDao;
#Test
#BeforeTransaction
public void test1Config() {
Assert.notNull(uzytkownikDao, "UzytkownikDao nie moze byc null");
}
#Test
#Transactional
#Rollback
public void test2Create() {
Uzytkownik u = new Uzytkownik();
u.setEmail("my4#uzytkownik.pl");
u.setHaslo("blablabla");
Assert.isTrue(!u.isIdUstawione());
u = uzytkownikDao.create(u);
Assert.notNull(u, "Uzytkownik nie moze byc null");
Assert.isTrue(u.isIdUstawione());
}
#Resource
public void setUzytkownikDao(UzytkownikDao uzytkownikDao) {
this.uzytkownikDao = uzytkownikDao;
}
}
Log:

Yes, I googled a lot this problem but didn't really find a solution. I have no idea what's wrong.
Any suggestions?

Answer 1

Do you are using InnoDB engine? MyISAM is the default engine form MySQL 5.x prior to 5.5 and does not support transactions - Wikipedia - MyISAM

Answer 2

Remove the following Hibernate property, it conflicts with Spring transaction management:
<prop key="hibernate.current_session_context_class">thread</prop>
