How to do transaction management without using @transactional annotations

Question

I have a transaction manager bean in my xml as follows :

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

and session factory and data source beans as :

<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
    <property name="URL" value="jdbc:oracle:thin:@localhost:1521:XE"/>
    <property name="user" value="user"/>
    <property name="password" value="password"/>
</bean>

<!--   Hibernate SessionFactory -->

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

with session factory having all the hbm files mapping .

Now I have a UserAddressManagerImpl as follows :

public class UserAddressManagerImpl implements UserAddressManager{
 // methods to read and write in the database
}

and the bean for this is :

<bean id="userAddressManager"   class="com.sodiz.service.impl.UserAddressManagerImpl">  

Now , this UserAddressManagerImpl doesn't have @Transactional on it .

Whenever I make any read operation from this class it works well but when making write operation it fails.

I am using this class packaged in a jar. So I prefer not to change this class.

So, is there any way to perform the read and write operations without using @Transactional annotations?

Answer 1

You would have to use aspects to achieve this without using the annotations:

<bean id="transactionManager" 
   class="org.springframework.orm.hibernate4.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

<bean id="userAddressManager" class="com.sodiz.service.impl.UserAddressManagerImpl"/>

<tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*"/>
        </tx:attributes>
</tx:advice>

<aop:config>
   <aop:pointcut id="userAddressManagerOperation" 
       expression="execution(* com.sodiz.service.impl.UserAddressManagerImpl.*(..))"/>
   <aop:advisor advice-ref="txAdvice" pointcut-ref="userAddressManagerOperation"/>
</aop:config>

Of course you could use more wilcards so that every service in your package applies to the above transactional settings.
