3.订单控制器类 OrdersController.java

package lucky.controller;

import lucky.domain.Orders;
import lucky.service.IOrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

/**
 * 订单控制器
 * @Controller 此注解是Spring的ioc，用于创建对象，用于把当前类对象存入spring容器中
 * @RequestMapping url请求的一级目录
 * @Autowired 用于注入IProductService的对象
 */
@Controller
@RequestMapping(path = "/orders")
public class OrdersController {
    @Autowired
    private IOrderService iOrderService;

    @RequestMapping(path = "/queryAll")
    public ModelAndView queryAll() throws Exception{
        ModelAndView mv=new ModelAndView();
        List<Orders> orders = iOrderService.queryAll();
        mv.addObject("ordersList",orders);
        mv.setViewName("orders-list");
        return mv;

    }
}

4.service层的接口及其实现类

(1)IOrderService.java

package lucky.service;

import lucky.domain.Orders;

import java.util.List;

public interface IOrderService {
    public List<Orders> queryAll() throws Exception;

}

(2)OrderServiceImpl.java

package lucky.service.impl;

import lucky.dao.IOrdersDao;
import lucky.domain.Orders;
import lucky.service.IOrderService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Service
@Transactional
public class OrderServiceImpl implements IOrderService {
    @Autowired
    private IOrdersDao iOrdersDao;

    @Override
    public List<Orders> queryAll() throws Exception {
        return iOrdersDao.queryAll();
    }
}

5.dao层

package lucky.dao;

import lucky.domain.Orders;
import lucky.domain.Product;
import org.apache.ibatis.annotations.One;
import org.apache.ibatis.annotations.Result;
import org.apache.ibatis.annotations.Results;
import org.apache.ibatis.annotations.Select;

import java.util.List;

public interface IOrdersDao {
    /**
     * 查询所有订单表
     * @return 查询结果
     * @throws Exception
     * @Select 查询的sql语句
     * @Results 映射查询结果集到实体类属性
     * column为数据库字段名，porperty为实体类属性名，jdbcType为数据库字段数据类型，id为是否为主键。
     * @One 当我们需要通过查询到的一个字段值作为参数，去执行另外一个方法来查询关联的内容，lucky.dao.queryById为要执行的方法
     */
    @Select("select * from LUCKY.ORDERS")
    @Results({
            @Result(id=true,property = "id",column = "id"),
            @Result(property = "orderNum",column = "orderNum"),
            @Result(property = "orderTime",column = "orderTime"),
            @Result(property = "orderStatus",column = "orderStatus"),
            @Result(property = "peopleCount",column = "peopleCount"),
            @Result(property = "payType",column = "payType"),
            @Result(property = "orderDesc",column = "orderDesc"),
            @Result(property = "product",column = "productId",javaType = Product.class,one = @One(select = "lucky.dao.IProductDao.queryById")),
    })
    public List<Orders> queryAll() throws Exception;
}

6.查询结果
