Building a marketplace with Spring Boot? Let us review it.
Expert code review for marketplace apps built with Spring Boot. We fix Spring Boot-specific security gaps, optimize performance, and handle deployment. From $19.
Common Spring Boot issues we find
Real problems from Spring Boot codebases we've reviewed.
Open actuator endpoints
Spring Boot Actuator endpoints like /actuator/env and /actuator/heapdump exposed without authentication, leaking environment variables, secrets, and heap memory.
Disabled Spring Security defaults
CSRF protection, CORS restrictions, and security headers disabled in SecurityFilterChain to 'make things work' during development and never re-enabled.
N+1 queries in JPA/Hibernate
Lazy-loaded entity relationships fetched inside loops, generating hundreds of individual SQL queries instead of proper JOIN FETCH or EntityGraph queries.
Missing @Transactional boundaries
Service methods that perform multiple database operations without transaction annotations, leaving data inconsistent if any step fails.
Marketplace challenges to solve
Key marketplace concerns that AI-generated code often misses.
Payment splitting and payouts
Buyers pay, the platform takes a cut, sellers receive the rest. This requires Stripe Connect or similar — significantly more complex than basic checkout. AI tools rarely implement this correctly, leaving you with manual payout processes.
Two-sided authorization
Sellers can manage their listings but not other sellers'. Buyers can view listings but only manage their own orders. Admins can moderate everything. Three distinct permission levels, all enforced server-side.
Trust and safety
Reviews, ratings, dispute resolution, content moderation, and fraud detection. These are complex systems that AI tools don't generate but that make or break a marketplace.
Search and discovery
Users need to find what they're looking for. Basic database queries won't cut it at scale — you need full-text search, filters, sorting, and potentially geolocation. This requires proper indexing or a dedicated search service.
What we check
Key areas we review for Spring Boot marketplace projects.
Payment flow — Stripe Connect setup, split payments, seller payouts
Authorization — buyer vs seller vs admin permissions enforced server-side
Data integrity — race conditions, inventory management, order state machines
Search performance — indexing, query optimization, full-text search
