I have a web application set up with MyBatis and Spring, but it doesn’t seem to be using any transactions. Here’s the configuration:

applicationContext.xml:

<tx:annotation-driven />

<!-- <tx:jta-transaction-manager /> --> <!-- using WebSphere 7 -->

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="jdbc/my_datasource" />
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="configLocation" value="WEB-INF/mybatis-config.xml" />
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="testDAO" class="org.mybatis.spring.mapper.MapperFactoryBean">
    <property name="mapperInterface" value="com.lmig.TestDAO" />
    <property name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

Sample bean method with transaction definition:

@Transactional(propagation = Propagation.REQUIRED)
public void testDelete() {
    testDAO.firstDelete(); //always successful
    testDAO.secondDelete(); //always throws SQLServerException
}

TestDAO:

public interface TestDAO {
    public void firstDelete();
    public void secondDelete();
}

Server debug log:

...SQLServerException follows...

Since secondDelete() throws an exception, the entire transaction would be expected to roll back. However, this isn’t the case, and the firstDelete() is still committed. I’ve tried all combinations of the transaction manager config (Spring-managed, app server-managed, both) but I keep getting the same results. Any idea what I’m doing wrong?

I’m using Mybatis 3, Spring 3 on WebSphere 7 with SQL Server 2005 as the DB.

    I figured this out: my testDelete() method wasn’t a Spring-managed bean, so it wasn’t participating in Spring-managed transactions. I changed my configuration to this, and now it’s working.
