Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Creation and Usage of BOM in Gradle
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.

Setting up swagger
I would suggest using Springdoc

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

What do you think about generating OpenAPI specs from code?
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.

Removies
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

Pulling out OpenAPI 3.0 Specifications from SpringBoot
Libraries like Springdoc or Springfox can do this. These libraries generate the OpenAPI documentation based on your controllers (+ you can apply the OpenAPI annotations on your controllers). This documentation is then exposed as a REST API, for Springdoc these can be found at /v3/api-docs.

Eureka Service Registration and Discovery
Retrieving all endpoints of a service isn't the goal of a service registry like Eureka, so no, you can't get all endpoints of a service. You can use a library like Springfox or Springdoc to enable Swagger/OpenAPI for your project. These libraries generate a JSON REST API (and a user interface) to view all your endpoints. You can even provide additional information (eg. default values, descriptions, ...) by adding some additional annotations on your controllers.

Java Spring EventSourcing and CQRS Clean Architecture microservice 👋⚡️💫
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.

URL Shortener: Java & Spring complete tutorial
Now Swagger UI is configured and we can start documenting our API. Inside UrlController, above every endpoint, we can use @ApiOperation annotation to add description. Depending on your needs you can use some other annotations.

Using Swagger API
Here is an example from Swagger APIs GitHub:

Organize code by concepts, not layers
Im mostly in C# land nowadays, but this seems to be the java version. I’m not sure it is as deeply integrated, as I think Java has a few popular server frameworks.
