Project
Spring Boot Playground
An opinionated Spring service starter that turns “how should we begin?” into a reusable contract across service creation, deployment, and release discipline.
Proof
- Defines a starter contract instead of leaving service shape to convention drift.
- Includes CI workflow, release process, ADRs, and Helm support in the repository itself.
- Separates default and advanced variants rather than pretending one stack fits every service.
For
- Teams standardizing how internal services are started
- Platform engineers who need a starter with governance, not just code scaffolding
- JVM teams deciding when to stay with MVC versus move to reactive variants
Stack
- Java 21
- Spring Boot 3
- PostgreSQL
- Flyway
- Docker Compose
- Helm
What it is
This repository is less about “sample code” and more about institutionalizing good defaults. The core value is not the generated service itself. It is the contract around how new services begin, what they ship with, and what gets treated as optional instead of mandatory.
Why it matters
Many starter repositories are honest time savers but weak platform assets. They generate code once and then disappear from the engineering conversation. This one is more useful because it pushes into governance: release readiness, CI, Helm, support expectations, and architectural decision records.
What makes it credible
The strong signal here is the explicit split between the default mvc-jpa path and the supported
advanced webflux-r2dbc variant. That is the kind of design decision platform teams usually avoid
writing down. Making it explicit is what turns the repo from template clutter into engineering
positioning.
Where it fits
This project supports the part of my work that is less visible than a benchmark or an AI integration: creating service standards that keep teams moving without locking them into accidental complexity.
