spring-boot-microservices
Standards for Feign clients and asynchronous messaging with Spring Cloud Stream. Use when implementing Feign HTTP clients or async event messaging in Spring Boot microservices. (triggers: **/*Client.java, **/*Consumer.java, feign-client, spring-cloud-stream, rabbitmq, resilience4j)
Best use case
spring-boot-microservices is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using spring-boot-microservices should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Spring Boot Microservices Standards ## **Priority: P0** ## Implementation Guidelines ### Sync Communication (REST & API Interface) - **Clients**: Use Spring Cloud OpenFeign or HTTP Interfaces (Spring 6/Java 21). - **Resilience**: Implement Resilience4j with Circuit Breaker, Retry (Exponential Backoff), and RateLimiter. - **Contracts**: Share DTO Records via a Maven BOM or API Contract module. - **Tracing**: Ensure Micrometer propagation for Distributed Tracing. See [implementation examples](references/implementation.md) for a Feign client with Circuit Breaker fallback. ### Async Communication (Spring Cloud Stream) - **Architecture**: Use Message-Driven patterns with Spring Cloud Stream. - **Functions**: Define message handlers as `java.util.function.Function`, `Consumer`, or `Supplier`. - **Serialization**: Use JSON or Avro for events. - **Reliability**: Implement Dead Letter Queues (DLQ) and idempotent consumers. See [implementation examples](references/implementation.md) for a Spring Cloud Stream event consumer with idempotency. ### Data & Isolation - **DB per Service**: NEVER share databases between microservices. - **Shared Libs**: Minimize shared logic to shared DTOs/Clients only. - **Discovery**: Use Spring Cloud Gateway for routing and auth. ## Anti-Patterns - **No Shared DB**: Services must communicate via APIs or Events only. - **No Shared Entities**: Share DTOs via Maven BOM, never JPA entities. - **No Sync Call Chains**: Use async messaging to prevent distributed monolith. ## References - [Implementation Examples](references/implementation.md)
