Developing and maintaining a Java GraphQL back-end
summary
Practical walkthrough shows how a Java service becomes a GraphQL endpoint with a few lines: annotate methods and POJOs, register them with the schema generator and keep one GraphQL runtime instance in a Spring controller. The repo named speaker implements dynamic schema generation, addresses N+1 with batch resolvers, defends against expensive queries via complexity scoring, depth limits and timeouts, and lets resolvers receive field selections to avoid select * and optimize SQL. GitHub sample included.
