Spring Boot 4: Enterprise Java Without the Boilerplate
Spring Boot is the standard framework for building production-grade Java applications — from REST APIs and batch jobs to reactive microservices and cloud-native deployments. Spring Boot 4 brings ahead-of-time compilation, native image support, and first-class AI integration into an ecosystem already trusted by tens of thousands of production systems. This track covers the complete framework, from wiring your first bean to deploying a GraalVM-compiled service with distributed tracing and resilience baked in.
What You Will Learn
You will build RESTful APIs with Spring Web and secure them with Spring Security, including OAuth2 and OIDC flows. You will persist and query data efficiently with Spring Data JPA, apply validation and structured error handling, and implement caching with Caffeine and Redis. Further into the track you will work with asynchronous messaging, batch processing with Spring Batch, GraphQL APIs, reactive pipelines with Spring WebFlux, and event-driven architecture with Spring Modulith. The final courses cover native image compilation with GraalVM, cloud-native observability, distributed tracing, resilience engineering, and building LLM-powered applications with Spring AI.
The Learning Path
Twenty-one courses progress from A1 through C2. The opening courses establish dependency injection, external configuration, and core Spring Boot mechanics. B-level courses move into real production concerns: REST API design, security, testing, microservices, caching, batch jobs, and GraphQL. The C1 tier shifts to performance and architecture — advanced data access, WebFlux, production readiness, Spring Modulith, advanced OAuth2, and GraalVM native images. The two C2 capstone courses address cloud-native observability and Spring AI integration, finishing with distributed tracing and resilience engineering.
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, so you can work through compilation errors, misconfigurations, and architectural questions without leaving the app.
