1.在需要整体回滚的方法上面添加注解:@Transactional(这个注解可以用在控制层和业务层都是可以的)
@GetMapping("/toCheckout")
@Transactional
public String toCheckout(HttpSession session,
Model model) throws Exception {
TUser user =(TUser) session.getAttribute(BookStoreConstants.USER_SESSION_KEY);
Cart cart = (Cart)session.getAttribute(BookStoreConstants.CART_SESSION_KEY);
TOrder tOrder = tOrderService.insertTOrder(cart, user);
tOrderItemService.batchTOrderItems(cart,tOrder);
Integer integer = tBookService.batchupdateBook(cart);
tBookService.selectBookStoreById(cart);
model.addAttribute("tOrderSquence",tOrder.getOrderSquence());
session.removeAttribute(BookStoreConstants.CART_SESSION_KEY);
return "pages/cart/checkout";
}
2.在主启动类上添加自动开启事务管理注解:@EnableTransactionManagement
@SpringBootApplication
@MapperScan("com.atguigu.mapper")
@EnableTransactionManagement
public class SpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootBookstoreApplication.class, args);
}
}
3.好了搞定!
