MyBatis-Spring设置不使用事务

2023年11月19日 363次阅读

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：

applicationContext.xml中：

<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
}

TestDAO：

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,因此整个事务将被回滚.但是,情况并非如此,并且仍然提交firstDelete().我已经尝试了事务管理器配置的所有组合(Spring管理,app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？

我在使用SQL Server 2005作为数据库的WebSphere 7上使用Mybatis 3,Spring 3.

最佳答案 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.我将配置更改为此,现在它正在运行.
