springdoc-openapi VS hibernate-validator

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.

The SpringDoc library comes with lots of annotations to tune your REST API specification precisely. Anyway, that's out of context of this article.

I found SpringDoc, a library that automates the generation of the spec from the source code. It relies on annotations for textual bits (like tags and descriptions), but it also infers stuff from Spring annotations.

This is an API made with Spring Web, uses springdoc-openapi-ui to expose a swagger-ui on http://localhost:8080/swagger-ui/index.html

The springdoc-openapi helps automating the generation of API documentation using Spring Boot projects GitHub - springdoc/springdoc-openapi

Our microservice accept http requests: For swagger used Swagger OpenAPI 3. The bank account REST controller, which accept requests, validate it using Hibernate Validator, then call command or query service. The main reason for CQRS gaining popularity is the ability to handle reads and writes separately due to severe differences in optimization techniques for those much more distinct operations.

We recently moved to https://springdoc.org/ since SpringFox is basically dead.

API documentation (https://springdoc.org/) is important.

For APIs that should be exposed publicly we use a solution based on springdoc-openapi that generates OpenAPI specification from Java/Kotlin classes. Non JVM services can expose OpenAPI specification by themselves on a dedicated endpoint. Thus, regardless of how the specification is created, it is a public contract.
