Java Microservices with Spring

Marcin Grzejszczak

OSS / Author / Mentor / Trainer

Learn how to do Microservices with Spring with Spring committer

The training introduces participants to microservices, discussing key concepts of dependency management and project generation. Participants learn how to create projects, manage configuration, and refresh the application configuration as it runs.

Participants will also focus on microservices communication. They will learn about service discovery, HTTP resilient communication and message-based communication. Practical exercises include creating HTTP applications, using circuit breakers and writing API gateways.

The training also focuses on application observability. Participants learn to monitor applications, create metrics, track distributed systems and test stability using chaos engineering. The training also covers the use of feature toggles.

What you’ll learn

Learn how to do Java Microservices with Spring with the Spring Framework and Micrometer committer.

  • Show dependency management with BOMs and platform projects.

  • Explain how to go beyond the 12th Factor App.

  • Learn how to do project standardization.

  • Configure apps with externalized configuration and profiles.

  • Demo live config refresh without restarting services.

  • Deploy the application to Kubernetes and observe dynamic configuration refresh.

  • Learn what service discovery is and how to use it.

  • Apply timeouts, retries, and circuit breakers in HTTP clients.

  • Make that work with reactive and imperative stacks.

  • Compare synchronous vs asynchronous communication patterns.

  • Build event-driven services using messaging brokers.

  • Implement API gateways for routing using reactive and imperative stacks.

  • Instrument code with metrics and traces using common API.

  • Visualize system behavior with dashboards and trace views.

  • Debug microservice flows using observability data.

  • Introduce controlled failures to validate system resilience.
