The project provides hands-on examples for registering and discovering microservice instances with Nacos, Eureka, or Consul, and for routing external API requests through Spring Cloud Gateway with support for filters and load balancing. The tutorials explore service resilience through circuit breakers and rate limiting with Sentinel and Hystrix, including custom fallback logic and traffic management rules that can be persisted in external stores like Nacos or Apollo. Distributed request tracing with Zipkin is demonstrated to correlate logs and timing data across services, while asynchronous messaging with Spring Cloud Stream covers retries, dead-letter queues, and delayed delivery for decoupled service communication. Configuration management is a major focus, with examples showing how to store settings centrally in Nacos, load configuration by environment or profile, refresh values dynamically without restarting, and share configuration across multiple applications. The project also covers declarative remote service invocation through annotated Java interfaces, client-side load balancing, and the integration of alternative RPC protocols like Dubbo alongside the standard Spring Cloud stack. The repository includes practical walkthroughs for deploying Nacos server clusters, persisting registry data to MySQL, and securing administrative interfaces with authentication. ## Tags ### Software Engineering & Architecture - [Microservice Demonstrations](https://awesome-repositories.com/f/software-engineering-architecture/spring-boot-integrations/microservice-demonstrations.md) — An educational project demonstrating Spring Cloud microservice patterns. - [API Gateways](https://awesome-repositories.com/f/software-engineering-architecture/api-gateways.md) — Implements API gateway patterns for routing external requests to internal microservices. - [Application Configuration](https://awesome-repositories.com/f/software-engineering-architecture/application-lifecycle-management/configuration-management/configuration-scopes/application-configuration.md) — Provides examples of storing and serving configuration properties centrally, allowing live updates without restarting services.
