### 2.5 上传图片 ###

我们尝试一下上传图片，发现请求负载是一个上传的图片的二进制

![image-20230818212224025][]

之后我们把图片上传到下图所示位置，但是这是未编译的资源

![image-20230818214451024][]

我们真正上传到服务器上的项目是编译后的项目

![image-20230818214838013][]

**简单来说我们图片的上传位置并不是未编译之前的位置，而是编译之后且部署到服务器的classes/static/img/upload位置**

所以我们在配置文件中就可以配置

#自定义属性 - 图片上传到的位置
    file:
      upload-path: "classpath:static/img/upload"
      #自定义属性 - 上传的图片保存数据库的访问路径的目录路径
      access-path: "/img/upload/"

这个upload-path可以理解为未编译时，存放到上面的图2，编译后存放到上图的图3

#### 2.5.1 Mapper ####

#### 2.5.2 Service ####

#### 2.5.3 Controller ####

    //      实现文件的上传
    //      拿到图片上传到的目录路径的file对象 - classpath:static/img/upload 图片要上传到的路径
            File uploadDirFile = ResourceUtils.getFile(uploadAddress);
    
    //        String file1 = Objects.requireNonNull(this.getClass().getClassLoader().getResource("static/image/upload/")).getFile();
    //        System.out.println(file1);
    
    //      我们之前封装目录路径的方式如下所示
    //      File f = new File(uploadAddress);
    //      现在我们并不能这么封装，因为这个路径是特殊的类路径的路径，我们需要一个特定的工具类进行解析
    
    //      拿到图片上传到的目录路径的磁盘路径
            String uploadDirPath = uploadDirFile.getAbsolutePath();
            log.info("uploadDirPath - "+uploadDirPath);
    
    //      拿到我们上传的图片的名称
            String originalFilename = file.getOriginalFilename();
    //      拿到上传的文件要保存到的磁盘文件的路径
            String uploadFilePath = uploadDirPath + "/" + originalFilename;
    //      File对象表示文件保存到的那个位置

        public int setStateByPid(@Param("productId")Integer productId,@Param("upDownState")String upDownState);

#### 3.1.3 Controller ####

    @RequestMapping("/state-change")
    public Result changeProductState(@RequestBody Product product) {
        
        return productService.updateStateByPid(product);
    }

### 3.2 修改商品 ###

#### 3.2.2 Service ####

@Value("${file.access-path}")

    //          说明图片被修改过了,product.getImgs()的值只是图片的名称
                product.setImgs(imageURL+product.getImgs());
            }
    
    //      修改商品信息
            int success = productMapper.setProductById(product);
    
            return success > 0 ? Result.ok("商品修改成功") : Result.err(501, "商品修改失败");

            product.setCreateBy(currentUser.getUserId());
    
            return productService.setProductById(product);
        }

## 四、删除商品 ##

### 4.1 Mapper ###

        int success = productMapper.removeProductByIds(productIdList);
        return success>0 ? Result.ok("商品删除成功"):Result.err(501,"商品删除失败");

        }

    ![image-20230819185218636][]
 *  **当商品采购到之后进行入库**

## 七、商品分类 ##

### 7.1 查询商品分类树 ###

这个地方在2.1写过，我们重新写一个接口即可

#### 7.1.1 Controller ####

//  查询商品分类树的url
        @RequestMapping("/product-category-tree")
        public Result productCategoryTree(){
        
    //      执行业务
         return  Result.ok(productTypeService.productTypeTree())  ;
        }

#### 7.1.2 效果图 ####

### 7.2 添加商品分类 ###

一种是添加一级分类，直接添加即可

![image-20230820135701043][]

一种是添加二级分类，需要先勾选一级分类

![image-20230820135732834][]

分类编码type\_code字段不能重复，这个地方的校验时当光标离开“分类编码”文本框的时候便开始校验

分类名type\_name字段不能重复

![image-20230820140145740][]

#### 7.2.1 Mapper ####

校验分类编码、分类名称是否重复的Mapper方法

//  根据分类编码或者分类名称查询商品分类的方法
        public ProductType findTypeByCodeOrName(ProductType productType);

<select id="findTypeByCodeOrName" resultType="com.pn.entity.ProductType">
            select *
            from product_type
            <where>
                <if test="typeName !=null and typeName != '' ">
                    type_name = #{typeName}
                </if>
                <if test="typeCode !=null and typeCode != '' ">
                   or type_code = #{typeCode}
                </if>
            </where>
        </select>

添加商品分类的Mapper方法

//  添加商品分类的方法
        public int insertProductType(ProductType productType);

<insert id="insertProductType">
        insert into product_type
        values (null, #{parentId}, #{typeCode}, #{typeName}, #{typeDesc})
    </insert>

#### 7.2.2 Service ####

> 校验分类编码、校验分类名称的业务方法分开，因为校验分类编码是否重复是在光标离开文本框的时候发送请求进行校验的，但是校验分类名称的时候是在提交表单数据的时候

校验分类编码是否重复的方法

@Override
        public Result checkTypeCode(String typeCode) {
        
    //      根据分类编码查询分类，并判断是否存在
            ProductType productType  = new ProductType();
            productType.setTypeCode(typeCode);
            ProductType prodType = productMapper.findTypeByCodeOrName(productType);
    
            return Result.ok(prodType == null);
        }

添加商品分类

@CacheEvict(key = "'all:typeTree'")
        @Override
        public Result saveProductType(ProductType productType) {
        
    //      首先校验一下分类名称是否存在
            ProductType prodType = new ProductType();
            prodType.setTypeName(productType.getTypeName());
            ProductType prodCategory = productMapper.findTypeByCodeOrName(prodType);
            if (prodCategory!=null){
        
                return Result.err(501,"分类名称已经存在");
            }
    
    //      分类名称不存在，添加分类
            int success = productMapper.insertProductType(productType);
    
            return success>0 ? Result.ok("添加分类成功") : Result.err(501,"添加分类失败");
        }

#### 7.2.3 Controller ####

校验分类编码是否重复的Controller

//  校验分类编码是否已经存在
        @RequestMapping("/verify-type-code")
        public Result checkTypeCode(String typeCode){
        
    //      执行业务
           return productTypeService.checkTypeCode(typeCode);
        }

添加商品分类Controller

//  添加商品分类的url接口
        @RequestMapping("/type-add")
        public Result addProductType(@RequestBody ProductType productType){
        
            return productTypeService.saveProductType(productType);

#### 7.2.4 效果图 ####

当“分类编码”文本框失去焦点后如下所示

添加商品分类

![image-20230820150537985][]

### 7.3 删除商品分类 ###

删除商品分类，我们要删除哪个商品分类，就勾选哪个商品分类

如果删除父级分类的话，子级分类也要删除

> 根据分类id或父级分类id删除分类

#### 7.3.1 Mapper ####

//  根据分类id或父级分类id删除分类的方法
        public int removeProductType(Integer typeId);

<delete id="removeProductType">
        delete
        from product_type
        where type_id = #{typeId} or parent_id = #{typeId}
    </delete>

#### 7.3.2 Service ####

@CacheEvict(key = "'all:typeTree'")
        @Override
        public Result deleteProductType(Integer typeId) {
        
            int success = productMapper.removeProductType(typeId);
    
            return success>0? Result.ok("删除成功") : Result.err(501,"删除失败");
        }

#### 7.3.3 Controller ####

//  删除商品分类
        @RequestMapping("/type-delete/{typeId}")
        public Result typeDelete(@PathVariable Integer typeId){
        
           return productTypeService.deleteProductType(typeId);
        }

### 7.4 修改商品分类 ###

只能改分类名称和分类描述

![image-20230820224152401][]

![image-20230820224224072][]

#### 7.4.1 Mapper ####

//  根据分类id修改分类的方法
        public int setProductTypeById(ProductType productType);

<update id="setProductTypeById">
        update product_type
        set type_name=#{typeName},
            type_desc=#{typeDesc}
        where type_id= #{typeId}
    </update>

#### 7.4.2 Service ####

@CacheEvict(key = "'all:typeTree'")
        @Override
        public Result setProductType(ProductType productType) {
        
    //      修改的分类名称是否已经存在
            ProductType prodType = new ProductType();
            prodType.setTypeName(productType.getTypeName());
            ProductType prodCategory = productMapper.findTypeByCodeOrName(prodType);
    
            if (prodCategory!=null && !prodCategory.getTypeId().equals((productType.getTypeId()))){
        
                return Result.err(501,"分类名称已经存在");
            }
    
            int success = productMapper.setProductTypeById(productType);
    
            return success>0? Result.ok("修改分类成功") : Result.err(501,"修改分类失败");
        }

#### 7.4.3 Controller ####

//  修改商品分类的url
        @RequestMapping("/type-update")
        public Result updateProductType(@RequestBody ProductType productType){
        
            return productTypeService.setProductType(productType);
        }
