Springcloud Learning
This project is a reference implementation of a distributed system built using Spring Cloud Alibaba, Spring Boot, and JDK 17. It serves as a comprehensive model for implementing a microservices architecture.
The system integrates a wide range of distributed patterns, including global transaction coordination for data consistency, OAuth2 and JWT for identity management, and Kubernetes-based container orchestration. It features a dedicated observability stack for distributed request tracing, log aggregation, and service health monitoring.
The implementation covers several functional domains, including e-commerce operations such as product inventory management, order processing, and marketing campaign execution. It also incorporates technical capabilities for asynchronous message queuing, distributed data caching, full-text search, and cloud object storage.
The project provides deployment templates for Kubernetes to manage the scaling and reliability of the microservices cluster.
Features
