spring2.0事务的嵌套

spring2.0事务的嵌套：

一个ServiceA:

public class ServiceA{

public int transactionDetailService(PaymentDetail detail)
   throws ServiceException {
  try {
     return dao.deletePaymentDetail(detail);
  } catch (DAOException ex) {
   logger .error("错误发生在：PaymentDetailServiceImpl.deletePaymentdetailService()方法中！");
   throw new ServiceException();
  }
 }

}

另一个ServiceB：

public class ServiceB{

public int deletePaymentInfoService(int payId) throws ServiceException {
  try {
         PaymentDetail detail = new PaymentDetail();
         detail.setPayId(payId);
          paymentDetailService.transactionDetailService(detail);
         dao.deletePaymentInfo(payId);     //如果这里执行删除操作失败的话，那么ServiceB的事务回滚，同时，内嵌事务ServiceA的事务也回滚；即transactionDetailService（）中的删除操作回滚。
        return 1;
      } catch (DAOException ex) {
   logger.error("错误发生在：PaymentInfoServiceImpl.deletePaymentInfoService(int payId)方法中！");
   throw new ServiceException();
    }
 }

}
