我在用Springboot构建商城网站后台，请帮我写出商品下单部分Service层代码，只需要写出核心代码即可，不用输出完整代码。
|
||||
不要用@Autowired（使用@Resource代替）

以下是goods表结构
|
||||
CREATE TABLE `goods` (
|
||||
`id` bigint(20) UNSIGNED NOT NULL AUTO_INCREMENT,
|
||||
`goods_name` varchar(127) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL COMMENT '商品名称，例如苹果、香蕉',
|
||||
`category_id` int(11) NULL DEFAULT 0 COMMENT '商品所属类目ID',

||||
`brand` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL DEFAULT '0' COMMENT '商品品牌',
|
||||
`brief` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL DEFAULT NULL COMMENT '商品简介，例如医用玻璃水银体温计腋下温度计',
|
||||
`is_on_sale` tinyint(1) NULL DEFAULT 1 COMMENT '是否上架 0为下架 1为上架',
|
||||
`sort_order` smallint(4) NULL DEFAULT 100 COMMENT '排序',
|
||||
`unit` varchar(31) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL DEFAULT '件' COMMENT '商品单位，例如件、盒',
|
||||
`counter_price` decimal(10, 2) NULL DEFAULT 0.00 COMMENT '专柜价格（原价 / 划线价）',
|
||||
`retail_price` decimal(10, 2) NULL DEFAULT 100000.00 COMMENT '零售价格（售价 / 未划线价）',
|
||||
`detail` text CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL COMMENT '商品详细介绍'
|
||||
)
|
||||
|
||||
以下是category_id的id和分类对应关系如下
|
||||
1 水果蔬菜
|
||||
2 日用品
|
||||
3 药品
|
||||
4 防疫物资
|
||||
5 零食
|
||||
6 肉类
|
||||
7 饮料酒水
|
||||
|
||||
在零食分类下，请帮我造一些商品的真实数据。注意商品分类id需要对应，另外商品描述需要简单描述一下这个商品是什么（不要带入人称），id设为null，detail不超过30个字，不少于10个字。
|
||||
|
||||
例如
|
||||
goods_name 洗发水
|
||||
brand 清扬男士
|
||||
brief 清扬男士去屑洗发露
|
||||
detail 清扬男士去屑洗发露，深层清洁头皮，去除头屑。适合男性使用。
|
||||
|
||||
输出应为一条Insert语句，包含多行数据
|
||||
|
||||
测试数据中不应包含以下商品或与其近似：
|
||||
方便面
|
||||
饼干
|
||||
口香糖
|
||||
薯片
|
||||
巧克力
|
||||
蜜饯
|
||||
牛肉干
|
||||
薄荷糖
|
||||
|
||||
|
||||
请再多生成一些，但是不要跟上面的重复

请帮我将以下表转换为Java POJO对象，不需要getter和setter
