rabbitMQ+redis+SpringBoot模擬高併發秒殺(源碼)！！！

效果展示：

模擬併發1000個請求秒殺10個商品

數據庫表信息：

商品數初始值爲10

使用壓測工具Jmeter模擬高併發

併發1000個請求

 

模擬手機號，從15100000000遞增

接口地址，參數設置

開始秒殺-----------------------

商品數量已經爲0

記錄表裏已成功記錄秒殺成功的手機號

源碼說明：

配置文件內容需改成自己環境的連接信息

 

 

需新建數據庫

表sql：

CREATE TABLE `goods` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(50) DEFAULT NULL COMMENT '商品名稱',
  `count` tinyint(11) NOT NULL DEFAULT '0' COMMENT ' 商品數量 ',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4;

CREATE TABLE `record` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `mobile` varchar(20) DEFAULT NULL COMMENT '手機號',
  `time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '秒殺成功時間',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=26 DEFAULT CHARSET=utf8mb4;
