    • Project mention: Show HN: Java REST without annotations, DI nor reactive streams | news.ycombinator.com | 2023-06-11

    This project reminds me of java spark [1]. I was always a cheerleader of the project. We even used it in production, loved the non-annotation centric approach.

  • springdoc-openapi

    Library for OpenAPI 3 with spring-boot

    • Project mention: Creation and Usage of BOM in Gradle | dev.to | 2024-01-07

    The issue is that the springdoc-openapi BOM brings an old version of the Spring Framework 6.0, which is incompatible with Spring Boot 3.2. There are several ways to solve this problem: update springdoc, change the order of BOM imports, but the best, in my opinion, is to avoid using the io.spring.dependency-management plugin.
