基于SpringBoot框架完成下列程序代码。实现点击超链接“删除订单”，发送请求，从数据库表order按Id删除对应订单信息的功能。 OrderList.html 文件信息如下： <div class="row" > <a th:href="@{'/delete/'+${orderId}}" > 删除订单 </a> </div> OrderController.java 文件信息如下： package order.controller; import … _______1______ public class OrderController { private OrderService orderService; @GetMapping("/__2__/{orderId}") public Order deleteOrder(@PathVariable("____3_____") Integer id) { Order order = orderService.deleteById(_______4_____); return order; } } OrderServiceImpl.java 文件信息如下： Package order.service.impl; import … ____5_____ public class OrderServiceImpl implements OrderService { ______6________ private OrderDao orderDao; @Override public Article deleteById(Integer orderId) { return______7____.deleteById(orderId); } } OrderDao.java 文件信息如下： package order.dao; import … ____8______ public interface OrderDao { Article deleteById(Integer orderId); } OrderMapper.xml 文件信息如下： <?xml version="1.0" encoding="UTF-8"?> <mapper namespace="____9_____"> <delete id="_____10_______" > delete from order where id = #{id} </select> </mapper>
