我有一个使用 MyBatis 和 Spring 设置的 Web 应用程序，但它似乎没有使用任何事务。这是配置：

应用程序上下文.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>

带有事务定义的示例 bean 方法：

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

测试道：

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

服务器调试日志：

...SQLServerException follows...

由于secondDelete()抛出异常，整个事务将被预期回滚。但是，事实并非如此，并且firstDelete()仍然承诺。我已经尝试了事务管理器配置的所有组合（Spring 管理，应用服务器管理，两者），但我一直得到相同的结果。知道我做错了什么吗？

我在 WebSphere 7 上使用 Mybatis 3、Spring 3 和 SQL Server 2005 作为数据库。

我想通了：我的testDelete()方法不是 Spring 管理的 bean，所以它没有参与 Spring 管理的事务。我将配置更改为这个，现在它可以工作了。
