SpringBoot 微信点餐系统学习记录六-订单表和订单详情表的后端开发

在dataobject文件夹创建订单表和订单详情表的实体类

package com.imooc.dataobject;

import com.imooc.enums.OrderStatusEnum;
import com.imooc.enums.PayStatusEnum;
import lombok.Data;
import org.hibernate.annotations.DynamicUpdate;

import javax.persistence.Entity;
import javax.persistence.Id;
import java.math.BigDecimal;
import java.util.Date;

/**
 * Created by Cdy1234 on 2018/7/24.
 *订单主表
 */
@Entity
@Data
@DynamicUpdate
public class OrderMaster  {

    /**订单ID**/
    @Id
    private  String orderId;

    /**买家姓名**/
    private  String buyerName;

    /**买家电话**/
    private  String buyerPhone;

    /**买家地址**/
    private  String buyerAddress;

    /**买家微信openId**/
    private  String buyerOpenid;

    /**订单总金额**/
    private  BigDecimal orderAmount;

    /**订单状态 默认为0，代表新订单**/
    private  Integer orderStatus= OrderStatusEnum.NEW.getCode();

    /**支付状态 默认为0，代表未支付**/
    private  Integer payStatus= PayStatusEnum.WAIT.getCode();

    /**订单创建时间**/
    private  Date createTime;

    /**更新时间**/
    private  Date updateTime;



}

package com.imooc.dataobject;

import lombok.Data;

import javax.persistence.Entity;
import javax.persistence.Id;
import java.math.BigDecimal;

/**
 * Created by Cdy1234 on 2018/8/7.
 *订单详情表
 */
@Entity
@Data
public class OrderDetail {
  @Id
  private String detailId;

  /**订单ID*/
  private String orderId;

  /**商品ID*/
  private String productId;

  /**商品名称*/
  private String productName;

  /**商品价格*/
  private BigDecimal productPrice;

  /**商品数量*/
  private Integer productQuantity;

  /***商品图片*/
  private String productIcon;


}

在DAO层创建对订单表的操作，继承JpaRepository，编写思路，订单详情是通过订单id查询，可能返回多个结果。所以是返回个list集合。

package com.imooc.repository;

import com.imooc.dataobject.OrderDetail;
import org.springframework.data.jpa.repository.JpaRepository;

import java.util.List;

/**
 * Created by Cdy1234 on 2018/8/11.
 * 订单详情表dao
 */

public interface OrderDetailRepository extends JpaRepository<OrderDetail,String>{
    /**
     * 根据Orderid 来查询订单详情，返回一条以上的记录，使用list集合。
     * @param orderId 订单id
     * @return
     */
    List<OrderDetail>findByOrderId(String orderId);


}

编写对订单主表的DAO层，继承JpaRepository，思路，查询用户的openid，可以是返回多个订单，所以返回一个Page。

package com.imooc.repository;

import com.imooc.dataobject.OrderMaster;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;

/**
 * Created by Cdy1234 on 2018/8/8.
 * 订单主表表dao层
 */

public interface OrderMasterRepository extends JpaRepository<OrderMaster,String>{

    /**
     * 根据用户id查询订单详情
     * @param buyerOpenid 用户的微信Open
     * @param pageable    第几页
     * @return Page      页数和用户下的订单详情
     */
   Page<OrderMaster>findByBuyerOpenid(String buyerOpenid, Pageable pageable);
}

测试DAO层OrderDetailRepository 的情况。右键OrderDetailRepository，选择go to--->Test

选择所编写的方法。创建OrderDetailRepositoryTest ，测试Save方法， Assert.assertNotNull(result)，只需要result不为空，就可以通过。

package com.imooc.repository;

import com.imooc.dataobject.OrderDetail;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.math.BigDecimal;

/**
 * Created by Cdy1234 on 2018/8/17.
 * 订单详情表DAO层
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class OrderDetailRepositoryTest {

    @Autowired
    private OrderDetailRepository repository;

    @Test
    public  void saveTest(){
        OrderDetail orderDetail=new OrderDetail();
        orderDetail.setDetailId("142342842988");
        orderDetail.setOrderId("1111321");
        orderDetail.setProductName("皮蛋粥");
        orderDetail.setProductIcon("http://xxx.jpg");
        orderDetail.setProductId("2332423");
        orderDetail.setProductPrice(new BigDecimal(12));
        orderDetail.setProductQuantity(20);
        OrderDetail result= repository.save(orderDetail);

        Assert.assertNotNull(result);
    }

    @Test
    public void testFindByOrderId() throws Exception {


    }
}

执行Save方法，数据表成功添加，测试成功。

测试订单主表DAO层测试，同上。

package com.imooc.repository;

import com.imooc.dataobject.OrderMaster;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.PageRequest;
import org.springframework.test.context.junit4.SpringRunner;

import java.math.BigDecimal;

/**
 * Created by Cdy1234 on 2018/8/17.
 * 订单主表测试
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class OrderMasterRepositoryTest {

    @Autowired
    private  OrderMasterRepository repository;

    private final String OPENID="110110";

    @Test
    public void SaveTest(){
        OrderMaster orderMaster=new OrderMaster();
        orderMaster.setOrderId("124323");
        orderMaster.setBuyerName("蔡中彩");
        orderMaster.setBuyerPhone("18060065761");
        orderMaster.setBuyerAddress("领袖天地");
        orderMaster.setBuyerOpenid(OPENID);
        orderMaster.setOrderAmount(new BigDecimal(2.3));
        OrderMaster result= repository.save(orderMaster);

        Assert.assertNotNull(result);


    }

    @Test
    public void testFindByBuyerOpenid() throws Exception {
        PageRequest requset=PageRequest.of(0,1);//调用PAgeRequest，该方法继承Pageable，
        Page<OrderMaster> result =repository.findByBuyerOpenid(OPENID,requset);
        Assert.assertNotEquals(0,result.getTotalElements());//不等于0，就运行通过
        System.out.println(result.getTotalElements());

    }
}

测试SaveTest方法。

运行成功
测试testFindByBuyerOpenid
测试成功
