A Spring Boot reviews service for a microservices marketplace, supporting ratings, responses, filters, artisan statistics, OpenAPI documentation, and service discovery.
DigiService’s reviews and evaluations domain is a Java 17 Spring Boot API with review and response lifecycles, validation, filters, rating statistics, OpenAPI documentation, health endpoints, Eureka registration, and gateway integration.
Create, read, update, delete, and filter reviews by artisan, client, status, or minimum rating.
Response Lifecycle
Separate endpoints manage replies to reviews by review or responding user.

01Reviews Service Architecture
The Angular marketplace calls a Spring Cloud gateway. Eureka routes requests to domain services, including the reviews service, which manages review and response data while using Feign clients for cross-domain validation.
Gateway
Single frontend entry point for platform APIs.
Reviews service
Independent review, response, and rating-statistics domain.
Adjacent services
User and artisan records are provided by adjacent domain services.
