У меня есть веб-приложение, настроенное с MyBatis и Spring, но оно, похоже, не использует транзакции. Вот конфигурация:
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>
Пример метода bean с определением транзакции:
@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();
}

...SQLServerException follows...
Поскольку secondDelete()
выдает исключение, ожидается, что вся транзакция будет откатываться. Тем не менее, это не так, и firstDelete()
все еще совершается. Я перепробовал все комбинации конфигурации менеджера транзакций (Spring-управляемого, управляемого сервером приложений, оба), но я продолжаю получать одинаковые результаты. Есть идеи, что я делаю не так?
Я использую Mybatis 3, Spring 3 в WebSphere 7 с SQL Server 2005 в качестве базы данных.
