Spring事务失败回滚

Question

我列出了一个问题“Spring事务失败回滚”。我有一个服务类，它调用2 DAO将数据插入到数据库表中。

 public void saveEmTrcvHeader(List<EmTrcvHeaderVOImpl> voList,  List<ResponseItem> responseItemList) {

        for (EmTrcvHeaderVOImpl vo : voList) {
            emTrcvHeaderDAO.create(vo);
            List<EmTrcvLineVOImpl> lineList = vo.getLineList();
            for (int i = 0; i < lineList.size(); i++) {
                EmTrcvLineVOImpl lineVo = lineList.get(i);
                lineVo.setEmTrcvHeaderId(vo.getEmTrcvHeaderId());
                lineVo.setProjId(null);
                emTrcvLineDAO.create(lineVo);

            }    

        }       

}

我的事务配置：

<bean id="txProxyTemplate" abstract="true" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
    <property name="transactionManager">
        <ref bean="transactionManager" />
    </property>
    <property name="proxyTargetClass">
        <value>true</value> 
    </property>
    <property name="transactionAttributes">
        <props>             
            <prop key="save*">PROPAGATION_REQUIRED,-java.lang.Exception,-org.springframework.dao.DataAccessException</prop>     
            <prop key="*">PROPAGATION_REQUIRED,-java.lang.Exception,-org.springframework.dao.DataAccessException</prop>
        </props>
    </property>
</bean>

我的服务和dao定义如下：

<bean name="emTrcvHeaderService" parent="txProxyTemplate">
    <property name="target">
      <bean class="com.emtrcv.service.EmTrcvHeaderService">
        <property name="emTrcvHeaderDAO">
          <ref bean="emTrcvHeaderDAO"/>
        </property>
         <property name="emTrcvPubSelectIdsDAO">
          <ref bean="emTrcvPubSelectIdsDAO"/>
        </property>
        <property name="emTrcvLineDAO">
          <ref bean="emTrcvLineDAO"/>
        </property>
      </bean>
    </property>
  </bean>
  <bean name="emTrcvHeaderDAO" class="com.emtrcv.dao.EmTrcvHeaderDAOImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
  </bean>
  <bean name="emTrcvPubSelectIdsDAO" class="com.emtrcv.dao.EmTrcvPubSelectIdsDAOImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
  </bean>
   <bean name="emTrcvLineDAO" class="com.emtrcv.dao.EmTrcvLineDAOImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
  </bean>

我想你必须提到回滚应该在什么时候发生。根据doc，回滚规则的概念很重要：它们使您能够指定哪些异常（和抛物）应该导致自动回滚。您可以在配置中以声明的方式指定它，而不是在Java代码中指定它。因此，尽管您仍然可以调用TransactionStatus对象上的setRollbackOnly（）来回滚当前事务，但通常您可以指定一个规则，即MyApplicationException必须始终导致回滚。
