is not working in apache camel

问题描述 投票:1回答:1

我有一个包含两个表,accountsA和accountsB的数据库。我想在同一个事务范围内对这两个数据库表做一些更新,所以我使用了组件,但是当更新accountsB时发生异常时,accountsA的更新正在继续,我需要我的数据库一起进行两个更新或者没有一个。

为了测试事务处理组件是否正常工作,我对accountB表名称进行了更改,产生了异常。我原以为accountA表的更新会停止,但不会发生。我做错什么了吗?

也许你只是省略了它,但你的问题中缺少的一个关键因素是DataSourceTransactionManager,使你的DataSource交易。

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