Spring Boot 3.5: Full Microservices Course

The Spring Boot 3.5 microservices course, built around a ticketing system. If your team is on the 3.x line rather than 4, this is the version that matches what you are running in production.

The shape of the course is the same as the Spring Boot 4 one: several independent services, their own data, and the operational concerns that come with splitting an application up.

What you build

A ticketing system split across several Spring Boot 3.5 services.

What you learn

• Wire services together through a gateway and a message broker
• Give each service its own database without losing consistency
• Add monitoring and health checks that are worth having

Before you start
