（1）spu保存

这个页面选择了手机之后，会调用查询分类品牌的接口，显示品牌，在分类品牌中添加了两个品牌后也会在这里显示出来

销售属性名称需要查询base_sale_attr表：

实体类：BaseSaleAttr

package com.atguigu.gmall.model.product;

import com.atguigu.gmall.model.base.BaseEntity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

/**
 * <p>
 * BaseSaleAttr
 * </p>
 *
 */
@Data
@ApiModel(description = "销售属性")
@TableName("base_sale_attr")
public class BaseSaleAttr extends BaseEntity {
	
	private static final long serialVersionUID = 1L;
	
	@ApiModelProperty(value = "销售属性名称")
	@TableField("name")
	private String name;

}

加载销售属性

创建mapper：BaseSaleAttrMapper

@Mapper
public interface BaseSaleAttrMapper extends BaseMapper<BaseSaleAttr> {
}

继续在MangeService添加接口


/**
 * 查询所有的销售属性数据
 * @return
 */
List<BaseSaleAttr> getBaseSaleAttrList();

实现类

@Autowired
private BaseSaleAttrMapper baseSaleAttrMapper;

@Override
public List<BaseSaleAttr> getBaseSaleAttrList() {
    return baseSaleAttrMapper.selectList(null);
}

继续在控制器SpuManageController添加接口：

@RestController
@RequestMapping("admin/product")
public class SpuManageController {

    // 引入服务层
    @Autowired
    private ManageService manageService;

    // 销售属性http://api.gmall.com/admin/product/baseSaleAttrList
    @GetMapping("baseSaleAttrList")
    public Result baseSaleAttrList(){
        // 查询所有的销售属性集合
        List<BaseSaleAttr>  baseSaleAttrList = manageService.getBaseSaleAttrList();

        return Result.ok(baseSaleAttrList);
    }
}

（2）保存后台代码

实体类：SpuInfo

package com.atguigu.gmall.model.product;

import com.atguigu.gmall.model.base.BaseEntity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.util.List;

/**
 * <p>
 * SpuInfo
 * </p>
 *
 */
@Data
@ApiModel(description = "SpuInfo")
@TableName("spu_info")
public class SpuInfo extends BaseEntity {
	
	private static final long serialVersionUID = 1L;
	
	@ApiModelProperty(value = "商品名称")
	@TableField("spu_name")
	private String spuName;

	@ApiModelProperty(value = "商品描述(后台简述）")
	@TableField("description")
	private String description;

	@ApiModelProperty(value = "三级分类id")
	@TableField("category3_id")
	private Long category3Id;

	@ApiModelProperty(value = "品牌id")
	@TableField("tm_id")
	private Long tmId;

	// 销售属性集合
	@TableField(exist = false)
	private List<SpuSaleAttr> spuSaleAttrList;

	// 商品的图片集合
	@TableField(exist = false)
	private List<SpuImage> spuImageList;

	// 商品的海报图片集合
	@TableField(exist = false)
	private List<SpuPoster> spuPosterList;
}

SpuImage ：spu图片实体类

package com.atguigu.gmall.model.product;

import com.atguigu.gmall.model.base.BaseEntity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

/**
 * <p>
 * SpuImage
 * </p>
 *
 */
@Data
@ApiModel(description = "Spu图片")
@TableName("spu_image")
public class SpuImage extends BaseEntity {
	
	private static final long serialVersionUID = 1L;
	
	@ApiModelProperty(value = "商品id")
	@TableField("spu_id")
	private Long spuId;

	@ApiModelProperty(value = "图片名称")
	@TableField("img_name")
	private String imgName;

	@ApiModelProperty(value = "图片路径")
	@TableField("img_url")
	private String imgUrl;

}

SpuPoster ：spu海报实体类

package com.atguigu.gmall.model.product;

import com.atguigu.gmall.model.base.BaseEntity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

/**
 * <p>
 * SpuPoster
 * </p>
 *

 */
@Data
@ApiModel(description = "SpuPoster")
@TableName("spu_poster")
public class SpuPoster extends BaseEntity {
	
	private static final long serialVersionUID = 1L;
	
	@ApiModelProperty(value = "商品id")
	@TableField("spu_id")
	private Long spuId;

	@ApiModelProperty(value = "文件名称")
	@TableField("img_name")
	private String imgName;

	@ApiModelProperty(value = "文件路径")
	@TableField("img_url")
	private String imgUrl;

}

SpuSaleAttr ：销售属性实体类

package com.atguigu.gmall.model.product;

import com.atguigu.gmall.model.base.BaseEntity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import java.util.List;

/**
 * <p>
 * SpuSaleAttr
 * </p>
 *
 */
@Data
@ApiModel(description = "销售属性")
@TableName("spu_sale_attr")
public class SpuSaleAttr extends BaseEntity {
	
	private static final long serialVersionUID = 1L;
	
	@ApiModelProperty(value = "商品id")
	@TableField("spu_id")
	private Long spuId;

	@ApiModelProperty(value = "销售属性id")
	@TableField("base_sale_attr_id")
	private Long baseSaleAttrId;

	@ApiModelProperty(value = "销售属性名称(冗余)")
	@TableField("sale_attr_name")
	private String saleAttrName;

	// 销售属性值对象集合
	@TableField(exist = false)
	List<SpuSaleAttrValue> spuSaleAttrValueList;

}

SpuSaleAttrValue ：销售属性值实体类

package com.atguigu.gmall.model.product;

import com.atguigu.gmall.model.base.BaseEntity;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableName;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;


/**
 * <p>
 * SpuSaleAttrValue
 * </p>
 *
 */
@Data
@ApiModel(description = "销售属性值")
@TableName("spu_sale_attr_value")
public class SpuSaleAttrValue extends BaseEntity {
	
	private static final long serialVersionUID = 1L;
	
	@ApiModelProperty(value = "商品id")
	@TableField("spu_id")
	private Long spuId;

	@ApiModelProperty(value = "销售属性id")
	@TableField("base_sale_attr_id")
	private Long baseSaleAttrId;

	@ApiModelProperty(value = "销售属性值名称")
	@TableField("sale_attr_value_name")
	private String saleAttrValueName;

	@ApiModelProperty(value = "销售属性名称(冗余)")
	@TableField("sale_attr_name")
	private String saleAttrName;

	// 是否是默认选中状态
//	@TableField("sale_attr_name")
//	String isChecked;
	@TableField(exist = false)
	String isChecked;

}

创建mapper

建立对应的mapper 文件

SpuImageMapper、SpuSaleAttrMapper 、SpuSaleAttrValueMapper 、SpuPosterMapper

@Mapper
public interface SpuImageMapper extends BaseMapper<SpuImage> {
}
@Mapper
public interface SpuSaleAttrMapper extends BaseMapper<SpuSaleAttr> {

}
@Mapper
public interface SpuSaleAttrValueMapper extends BaseMapper<SpuSaleAttrValue> {
}
@Mapper
public interface SpuPosterMapper extends BaseMapper<SpuPoster> {
}

继续添加在接口添加代码

/**
 * 保存商品数据
 * @param spuInfo
 */
void saveSpuInfo(SpuInfo spuInfo);

实现类：

@Override
@Transactional(rollbackFor = Exception.class)
public void saveSpuInfo(SpuInfo spuInfo) {
    /*
        spuInfo;
        spuImage;
        spuSaleAttr;
        spuSaleAttrValue;
        spuPoster
     */
    //保存spu信息
    spuInfoMapper.insert(spuInfo);


  //保存图片
    //  获取到spuImage 集合数据
    List<SpuImage> spuImageList = spuInfo.getSpuImageList();
    //  判断不为空
    if (!CollectionUtils.isEmpty(spuImageList)){
        //  循环遍历
        for (SpuImage spuImage : spuImageList) {
            //  需要将spuId 赋值
            spuImage.setSpuId(spuInfo.getId());
            //  保存spuImge
            spuImageMapper.insert(spuImage);
        }
    }

//保存销售属性
    //  获取销售属性集合
    List<SpuSaleAttr> spuSaleAttrList = spuInfo.getSpuSaleAttrList();
    //  判断
    if (!CollectionUtils.isEmpty(spuSaleAttrList)){
        //  循环遍历
        for (SpuSaleAttr spuSaleAttr : spuSaleAttrList) {
            //  需要将spuId 赋值
            spuSaleAttr.setSpuId(spuInfo.getId());
            spuSaleAttrMapper.insert(spuSaleAttr);


        //保存销售属性值
            //  再此获取销售属性值集合
            List<SpuSaleAttrValue> spuSaleAttrValueList = spuSaleAttr.getSpuSaleAttrValueList();
            //  判断
            if (!CollectionUtils.isEmpty(spuSaleAttrValueList)){
                //  循环遍历
                for (SpuSaleAttrValue spuSaleAttrValue : spuSaleAttrValueList) {
                    //   需要将spuId， sale_attr_name 赋值
                    spuSaleAttrValue.setSpuId(spuInfo.getId());
                    spuSaleAttrValue.setSaleAttrName(spuSaleAttr.getSaleAttrName());
                    spuSaleAttrValueMapper.insert(spuSaleAttrValue);
                }
            }
        }
    }


//保存海报

    //  获取到posterList 集合数据
    List<SpuPoster> spuPosterList = spuInfo.getSpuPosterList();
    //  判断不为空
    if (!CollectionUtils.isEmpty(spuPosterList)){
        for (SpuPoster spuPoster : spuPosterList) {
            //  需要将spuId 赋值
            spuPoster.setSpuId(spuInfo.getId());
            //  保存spuPoster
            spuPosterMapper.insert(spuPoster);
        }
    }
}

继续在控制器添加代码

/**
 * 保存spu
 * @param spuInfo
 * @return
 */
@PostMapping("saveSpuInfo")
public Result saveSpuInfo(@RequestBody SpuInfo spuInfo){
    // 调用服务层的保存方法
    manageService.saveSpuInfo(spuInfo);
    return Result.ok();
}
