insert into table using hibernate #Transactional - mysql

Question

I am using #Transactional annotation to test inserting some data into one of the tables through a Spring application. My test succeeds, but I do not see any data being inserted into the table.
Here are the relevant code snippets:
MyTest:
#TransactionConfiguration(transactionManager="MyTxManager")
#Transactional
public class MyTest {
#Autowired
private DataProvider provider;
#Test
#Transactional
void testInsert() {
Order purchaseOrder = new Order("ID1", "LER", "VDR1", 0, );
provider.addRow(purchaseOrder);
}
}
DataProvider:
public class DataProvider extends DatabaseProvider {
// some stuff...
#Transactional
public void insertRow(Order purchaseOrder) {
/*
* SessionFactory is got through autowiring
* and is working perfectly fine.
*/
Session session = sessionFactory.getCurrentSession();
// This should save the row into the table - which it doesn't :(
session.save(purchaseOrder);
}
}
information-providers.xml
<bean id="DataProvider" class="com.util.DataProvider">
<property name="sessionFactory" ref="MySessionFactory" />
</bean>
hibernate.xml containing the configuration of session factory
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
parent="AbstractSessionFactory" depends-on="EnvironmentHelper">
<property name="hibernateProperties">
<props>
<prop key="hibernate.connection.autocommit">true</prop>
<prop key="hibernate.connection.provider_class">com.hibernate.ConnectionPool</prop>
<prop key="hibernate.connection.driver_class">${driverClassName}</prop>
<prop key="hibernate.connection.url">${databaseURL}</prop>
<prop key="hibernate.connection.username">${databaseUsername}</prop>
<prop key="hibernate.connection.password">${databasePassword}</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.default_schema">${databaseDefaultSchema}</prop>
</props>
</property>
</bean>
<!-- Use Spring transactions for Hibernate -->
<tx:annotation-driven transaction-manager="MyTxManager" mode='proxy' proxy-target-class='true'/>
<bean id="MyTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="MySessionFactory" />
</bean>
</beans>

Answer 1

I think the problem in rolling back the transactions. See here defaultRollback method.
Try like this:
#TransactionConfiguration(transactionManager="MyTxManager", defaultRollback=false)

Answer 2

Your problem is that MyProvider myProviderInstance = new MyProvider(); the myProviderInstance isn't maintained by Spring container, you just new it, so the Spring can't do anything about it, definitely the transaction doesn't work. You should config the bean in Spring applicationcontext.xml and load it with ApplicationtContext, you can find dozens of sample after google it. And since you use Mysql you should make sure that you use innerDB mode or the transaction isn't supported by mysql.

Answer 3

add the line <tx:annotation-driven/> to your spring configuration
