非常简单实用的前后端分离项目-仓库管理系统（Springboot+Vue）part 5（未实现预期目标）

进行文件功能的书写，依旧新建查询。

CREATE TABLE `goods_file` (
    `id` INT(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
    `goods_id` INT(11) NOT NULL COMMENT '物品ID，关联goods表',
    `file_name` VARCHAR(255) NOT NULL COMMENT '文件名',
    `file_path` VARCHAR(255) NOT NULL COMMENT '文件路径（相对于loadfile目录）',
    `file_size` BIGINT(20) DEFAULT NULL COMMENT '文件大小（字节）',
    `upload_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '上传时间',
    PRIMARY KEY (`id`),
    FOREIGN KEY (`goods_id`) REFERENCES `goods`(`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='对应文件表';

在代码生成器中，完成代码的生成

在wms和wms-web同级下加一个文件夹goodsfile用于存储文件。完善生成的六个代码
