Improve Your Developer Experience with Spring Boot Dev Services
summary
Spring Boot 3.1 auto-detects service dependencies and either generates or uses a Docker Compose file, runs docker compose up/down, and injects JDBC URL/username/password via a new ConnectionDetails abstraction so Hikari and other auto-configs just connect; Testcontainers integration adds @ServiceConnection for Testcontainers so tests and a test-only main can start containers without DynamicPropertySource; reuse and restart-scope options preserve state and cut startup to ~200ms for reused Postgres; works with Postgres, Redis, Kafka, Elasticsearch, Cassandra.
