Spring MVC + mybatis + mysql transaction rollback service layer, annotate the transaction with @Transactional.
1. The mysql table creation engine is set to INNODB, such as:
ALTER TABLE goods_order ENGINE = INNODB;
2. Service layer
public interface IGoodsOrderService {
/**
* Add order
* @param order
* @return
*/
boolean addOrder(GoodsOrder order) throws Exception;
}
@Service
public class GoodsOrderServiceImpl implements IGoodsOrderService {
@Autowired
private IGoodsOrderDao orderDao;
@Autowired
private IGoodsOrderDetailDao orderDetailDao;
@Autowired
private IGoodsOrderStatusDao orderStatusDao;
@Override
@Transactional(readOnly=false,propagation=Propagation.REQUIRED,rollbackFor=Exception.class)
public boolean addOrder(GoodsOrder order) throws Exception {
boolean result = false;
try {
if (null != order.getDetails() && order.getDetails().size() > 0) {
order.setOrderNum(order.getDetails().size());
// add order
orderDao.addGoodsOrder(order);
// add order details
for (GoodsOrderDetail orderDetail : order.getDetails()) {
// orderDetail.setOrderNo(order.getOrderNo());
orderDetailDao.addGoodsOrderDetail(orderDetail);
}
result = true;
}
} catch (Exception e) {
//Transaction rollback exception needs to be thrown
throw e;
}
return result;
}
}
