Framework

Design pattern

• spring-boot - alone, production-grade Spring-based applications, and the built-in web server lets you run projects like normal Java programs. In addition, most Spring Boot projects require only a small amount of configuration, which is different from Spring reconfiguration.
• spring-cloud-alibaba - stop solution for distributed application development. It contains all the components required to develop distributed applications, making it easy for you to develop your applications using Spring Cloud.
• flink - and batch-processing capabilities.
• Sentinel
• dubbo - performance, java based, open source RPC framework.
• spring-cloud-kubernetes
• skywalking - based (Docker, Kubernetes, Mesos) architectures.
• seata - to-use, high-performance, open source distributed transaction solution.

Practical Project

Others

• FEBS-Shiro
• mall - commerce systems, including a front-end mall system and a back-end management system, which are implemented based on SpringBoot + MyBatis.
• mall-swarm - swarm is a set of micro-service mall system, which adopts core technologies such as Spring Cloud Greenwich, Spring Boot 2, MyBatis, Docker and Elasticsearch, and meanwhile provides a management background based on Vue to facilitate and quickly set up the system
