Java秒杀项目需求汇总

1.环境搭建&&数据表设计

SpringBoot+Mybatis+Druid+Thymeleaf
Jedis+通用缓存Key封装
Result结果集封装

通用缓存Key封装: 采用接口+抽象类+实现类的模板模式。这样做能偶避免键重复，导致值被覆盖。

//1.商品表
CREATE TABLE `goods`(
  `id` BIGINT(20) NOT NULL AUTO_INCREMENT COMMENT "商品ID",
  `goods_name` VARCHAR(16) DEFAULT NULL COMMENT "商品名称",

  `goods_price` DECIMAL(10,2) DEFAULT 0.00 COMMENT "商品单价",
  `goods_stock` INT(11) DEFAULT 0 COMMENT "商品库存，-1表示没有限制",
  PRIMARY KEY(`id`)
