springboot集成开发实现商场秒杀
加入主要依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!-- alibaba的druid数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.5</version> </dependency> <!-- redis客服端--> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.38</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-validation</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-amqp</artifactId> </dependency> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>19.0</version>
秒杀项目主要目录构架
1.java目录
config 所有的配置信息
controller
exception 所有业务异常
mapper
service
rabbitmq
redis redis缓存
validator 后端校验
bean:数据传输层包括：mysql以及redis
util：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
