Online shopping project:

We have adopted a microservice architecture and adopted the SpringCloud technology stack for microservice technology. Each microservice site is built on SpringBoot and connected with the functionality of each microservice using SpringCloud Gateway to form a set of systems. At the same time, we have implemented filtering and flow limiting strategies in the microservice gateway to protect and authenticate microservices. The project adopts SpringSecurity OAuth2.0 to solve single sign on and user authorization between various microservices. Seata was adopted to address distributed transactions between microservices. We have adopted Elasticsearch to solve real-time retrieval of massive products. MySQL is used for data storage, combined with Canal to achieve data synchronization operations, and Redis is used for data caching operations. RabbitMQ is used to achieve asynchronous communication between various microservices. We use OpenResty integrated Nginx to control the massive concurrency at the outermost layer of microservices, and utilize Keepalive+Nginx to solve Nginx's single point of failure problem.
