Spring Boot Template v1.0

A pragmatic Spring Boot
foundation.

For Java teams that ship. Hexagonal architecture, OAuth2 + Keycloak, structured observability, and a Docker-ready local environment — wired from day one.

// Root problem

Every Spring project
re-litigates the same setup.

Spring config sprawl

XML, YAML, Java config, profiles — every Spring Boot project re-litigates the same setup decisions for two weeks before shipping a feature.

Auth bolt-ons

OAuth2, JWT, Keycloak — every team wires the same security plumbing differently. Half of them have subtle bugs.

Build & deploy chaos

Maven vs. Gradle, multi-module structure, Dockerfile, Helm chart — bespoke for every project, none of it reusable.

// Three pillars

Designed for production from day one.

01

Hexagonal architecture

Ports and adapters with clear boundaries. Domain logic stays free of framework concerns; infrastructure is swappable.

02

Production defaults

OAuth2 resource server, Spring Security, Flyway migrations, Resilience4j, Micrometer — wired and configured from day one.

03

Observability built in

Structured logging, distributed tracing (OpenTelemetry), Prometheus metrics, health checks — production-grade from commit one.

// Out of the box

What's already wired.

Auth

OAuth2 + Keycloak

Resource server with JWT validation, introspection, scope-based authorization. Plug your IdP in and ship.

Data

Multi-database support

PostgreSQL primary, MySQL alternative. JPA + Flyway migrations + connection pooling pre-tuned for production.

API

OpenAPI-first

Spring Doc generates schema + Swagger UI automatically. Contract-driven; clients can codegen against you from day one.

Events

Async messaging

Kafka or RabbitMQ adapters; outbox pattern for reliable delivery. Built-in dead-letter handling and retries.

Resilience

Circuit breakers

Resilience4j wired into every external call. Bulkheads, retries, rate limiting — defaults that survive load tests.

DevEx

One-command bootstrap

Local dev environment with Docker Compose: Postgres, Keycloak, Kafka, observability stack — all running in 90 seconds.

// Engagement

Same engagement model as Pragmatic .NET.
