一、具体实现截图

简单介绍：
使用三端分离，会员端、控台端、服务端，便于开发和维护，同时将界面与功能逻辑分开，易于分配不同的资源。使用微服务生态组件：注册中心、配置中心、网关、限流降级、分布式事务、服务调用，保障服务高可用。将系统功能拆分成多个微服务应用，实现服务间低耦合，服务内功能高内聚。使用Redis、MQ等中间件，提升系统性能，保障服务高性能响应。

二、技术栈

①.SpringBoot3.0体系

自动配置与约定优于配置简化了项目配置，提供默认配置，减少了开发者的工作量。快速开发集成了大量常用功能，通过注解和约定，减少了样板代码，提高了开发效率。嵌入式服务器支持常见的嵌入式服务器，如Tomcat、Jetty，方便打包成可执行JAR文件。微服务支持提供了Spring Cloud等工具，支持微服务开发和管理。Spring生态系统整合可轻松整合Spring框架中的各种组件，如Spring Data、Spring Security等。广泛的社区支持拥有庞大的社区，提供了丰富的文档和解决方案。
Spring Boot的使用优势在于简化开发、提高效率、支持微服务等方面，使得Java开发更加便捷和灵活。如有新版本发布，请查阅最新文档以获取详细信息。

②.第三方组件集成

含：Mybatis、Redis、RocketMQ、Quartz；

③.设计亮点

WT单点登录、项目分层设计、分库分表、自制前后端代码生成器

④.前端Vue3

Vue CLI 5、Ref、Reactiev、Axios、Router、Vuex、Ant Design Vue、多环境配置、编译与部署

⑤.前高并发秒杀技术

高并发秒杀技术、缓存、限流、熔断、JWT令牌、令牌大闸、削峰填谷、分布式锁
