Spring Boot for Microservices and REST APIs
Spring Boot is the standard Java framework for building production-grade REST APIs and microservices. It handles configuration, dependency injection, data persistence, and observability out of the box, so you can focus on application logic instead of boilerplate. This track covers Spring Boot 4 from a first REST endpoint all the way to distributed, cloud-deployed microservices — grounded in the patterns used in real backend systems.
What You Will Learn
You will build and secure REST APIs, manage the full bean lifecycle with dependency injection, and persist data with Spring Data JPA. From there you will add observability with Actuator, validate inputs, handle exceptions globally, and document APIs with SpringDoc OpenAPI. The advanced material covers caching with Redis, batch processing, event-driven architecture with Kafka, reactive programming with WebFlux, distributed tracing with Micrometer and Zipkin, service discovery, and API gateways. The track closes with cloud deployment strategies, resilience patterns, and performance and scalability optimization.
The Learning Path
Twenty-four courses progress from A1 through C2. The opening course covers Spring Boot and REST API fundamentals at A1, followed by configuration, profiles, and the bean lifecycle at A2–B1. The B2 block is the largest: advanced REST API design, security, testing with JUnit, MockMvc and Testcontainers, advanced Spring Data JPA, caching, Spring Batch, centralized config with Spring Cloud Config, and an introduction to microservices architecture. The C1 and C2 courses cover the most demanding topics — event-driven microservices with Kafka, reactive programming with WebFlux, distributed tracing, service discovery, cloud deployment, building resilient microservices, and performance and scalability optimization.
How It Works
Each course is split into short, focused lessons you complete in the built-in code editor with real-time feedback. An AI tutor is available whenever you get stuck, and every concept is reinforced with hands-on exercises rather than passive reading.
