devslab-kit

A reusable Spring Boot 4 platform starter. Drop it into an application and get authentication, authorization, multi-tenancy, dynamic menus and audit logging from auto-configuration — plus an admin REST API and a ready-made admin console — so each product can focus on its own domain instead of rebuilding the platform layer.

devslab-kit is deliberately product-agnostic: it knows only platform concepts (UserId, TenantId, Permission, Role, Menu, Audit), never a specific product's domain.

Status — pre-1.0

The platform is feature-complete for 0.1.0, the first public release. Artifacts publish to Maven Central from 0.1.0 onward.

What you get

  • Identity

    Users, BCrypt credentials, JWT issue/parse, configurable login lockout, forced password change.

  • Access

    Roles, permissions, subject groups, and an ABAC policy SPI on top of RBAC.

  • Multi-tenancy

    A tenant context that is always present, with pluggable resolvers — fixed, header, jwt, subdomain.

  • Dynamic menus

    Permission-filtered menu trees, computed per user.

  • Audit logging

    Asynchronous audit trail through ApplicationEventPublisher, persisted to PostgreSQL.

  • Pluggable cache

    in-memory, redis, or none. The Redis backend owns JSON serialization — no Serializable, no serializer wiring.

  • Config sync

    Promote permissions, roles and menus across environments as a code-keyed export/import bundle — merge or mirror, dry-run first (guide).

Why a starter?

Every product the team builds needs the same platform layer: who is the user, what can they do, which tenant are they in, what changed, and an admin surface to manage it all. devslab-kit provides that layer once, override-friendly:

  • Auto-configured. Add the starter, point it at PostgreSQL, boot.
  • Override-friendly. Every default bean is @ConditionalOnMissingBean — replace any piece by declaring your own.
  • Contracts are Java APIs. Each capability is split into a thin -api contract and a -core default; depend on the -api alone to supply your own implementation.

Next steps

The companion devslab-kit-admin-ui (Vue 3 + PrimeVue) is a ready-made console over the admin REST API.
