Does Your API Need a REST? Check Out GraphQL.
summary
GraphQL replaces multiple REST fetches with a single POST to /graphql so a product page that used three REST calls becomes one query, and Spring integrates it via graphql-java plus Spring for GraphQL (starter, auto‑config, metrics). Schema files live under src/main/resources as schema.graphqls, controllers use @QueryMapping/@MutationMapping/@SchemaMapping and @Argument, input types require input definitions, pagination follows the cursor connection spec (Spring for GraphQL 1.2, Spring Boot 3.1, JDK 17), and observability, security, and testing are built in.
