Spring Boot microservices are small Spring Boot applications that each own one business capability and call each other over the network. This tutorial builds a complete library system on Spring Boot 4.1 with Spring Cloud Gateway, HTTP interface clients, Resilience4j retry and circuit breaker, OpenTelemetry tracing with one trace id across services, Docker Compose and WireMock tests, and explains when not to use microservices.
Spring helps write high-performing, easily testable, and reusable code and promotes programming best practices by applying dependency injection (DI).
