Review-v2 (Sprint-0-Plan-Review-v2) blockers: - B1: SecurityConfig chain now securityMatcher-scoped to plate-auth endpoints so it cannot hijack the consuming app's routes - B2: removed @ComponentScan from auto-config; explicit @Import of @Configuration + @Service/@RestController classes - B4: CORS fails closed (same-origin) when allowed-origins empty instead of defaulting to '*' - B5: removed dead RefreshToken entity + repo; v0.1 uses stateless JWT refresh (rotation deferred to v0.3) - W-A: documented OnboardingHook transaction contract Verified: mvn -pl plate-auth-starter compile succeeds.
plate-auth
Reusable authentication + multi-tenancy library for Spring Boot 4 + NextAuth v5.
Two artifacts, one contract
| Artifact | Registry | Purpose |
|---|---|---|
de.platesoft:plate-auth-starter |
Gitea Maven | Spring Boot auto-config: JWT, OAuth, memberships, invitations, access requests |
@platesoft/auth |
Gitea npm | NextAuth v5 config factory, HMAC exchange, proxy helpers, React hooks |
The wire contract between them is an HMAC-SHA256 signed exchange envelope + JWT bearer tokens.

Backend (Spring Boot 4)
<dependency>
<groupId>de.platesoft</groupId>
<artifactId>plate-auth-starter</artifactId>
<version>0.1.0</version>
</dependency>
plate:
auth:
jwt:
secret: ${PLATE_AUTH_JWT_SECRET} # ≥32 chars
exchange:
secret: ${PLATE_AUTH_EXCHANGE_SECRET} # ≥32 chars, shared with frontend
Frontend (Next.js 15 + NextAuth v5)
pnpm add @platesoft/auth@0.1.0 --registry=https://git.plate-software.de/api/packages/pplate/npm/
// app/api/auth/[...nextauth]/route.ts
import NextAuth from 'next-auth';
import { createAuthConfig } from '@platesoft/auth/config';
const config = createAuthConfig({
providers: { google: { clientId: process.env.GOOGLE_CLIENT_ID!, clientSecret: process.env.GOOGLE_CLIENT_SECRET! } },
exchange: { backendUrl: process.env.NEXT_PUBLIC_BACKEND_URL!, secret: process.env.NEXTAUTH_EXCHANGE_SECRET! },
});
export const { handlers, auth, signIn, signOut } = NextAuth(config);
export const { GET, POST } = handlers;
