springboot集成开发实现商场秒杀

加入主要依赖

org.springframework.boot spring-boot-starter-thymeleaf com.alibaba druid 1.0.5 redis.clients jedis com.alibaba fastjson 1.2.38 commons-codec commons-codec org.springframework.boot spring-boot-starter-validation org.springframework.boot spring-boot-starter-amqp com.google.guava guava 19.0

秒杀项目主要目录构架

1.java目录

config 所有的配置信息controllerexception 所有业务异常mapperservicerabbitmqredis redis缓存validator 后端校验bean:数据传输层包括：mysql以及redisutil：工具包dto:数据传输对象

秒杀系统逻辑

实现技术点

1.MD5

实现用户的密码为加密在保存到数据库之前

2.全局异常统一处理

通过拦截所有异常，对各种异常进行相应的处理

3.页面缓存

通过手动渲染的html页面缓存到redis中

WebContext ctx = new WebContext(request, response, request.getServletContext(), request.getLocale(), model.asMap());html = thymeleafViewResolver.getTemplateEngine().process("goods_detail", ctx);

4.解决了超买
