根据代码信息,需要填写的内容如下:
1. OrderController类需要导入OrderService,代码可能如下:
```
import order.service.OrderService;
```
2. @GetMapping注解中的路径应该为"/delete",代码可能如下:
```
@GetMapping("/delete/{orderId}")
```
3. @PathVariable注解中的参数应该为"orderId",代码可能如下:
```
@PathVariable("orderId")
```
4. deleteById方法需要传入orderId参数,代码可能如下:
```
Order order = orderService.deleteById(orderId);
```
5. OrderServiceImpl类需要实现OrderService接口,代码可能如下:
```
public class OrderServiceImpl implements OrderService {
// 实现OrderService接口中的方法
}
```
6. OrderServiceImpl类中的orderDao属性可以使用@Autowired注解自动注入,代码可能如下:
```
@Autowired
private OrderDao orderDao;
```
7. deleteById方法需要返回Order对象,代码可能如下:
```
public Order deleteById(Integer orderId) {
return orderDao.deleteById(orderId);
}
```
8. OrderDao类需要导入Order实体类,代码可能如下:
```
import order.entity.Order;
```
9. OrderMapper.xml文件中的namespace应该为"order.dao.OrderDao",代码可能如下:
```
<mapper namespace="order.dao.OrderDao">
```
10. delete标签的id属性应该为"deleteById",代码可能如下:
```
<delete id="deleteById" >
delete from order where id = #{id}
</delete>
```
