Building a Flexible GraphQL API with Spring Boot and Query by Example

Build a flexible book management GraphQL API from scratch using Spring Boot and Query by Example (QBE) in this 21-minute tutorial. Master the implementation of a dynamic search API that handles multiple search parameters without writing complex query methods. Follow along to set up a Spring Boot project with GraphQL and JPA, utilize the @GraphQLRepository annotation for automatic query mapping, and implement Query by Example for flexible searching. Learn to create and test the API using the GraphQL playground while eliminating boilerplate code. Progress through hands-on demonstrations covering project setup, schema creation, entity implementation, repository configuration, and comprehensive API testing. Access the complete source code via GitHub and explore additional resources through the accompanying blog post and related video content on Spring Boot, GraphQL fundamentals, Docker integration, and Query by Example implementations.
