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.

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

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.

I created a library that exports your Spring endpoints into a Postman collection! Please, let me know what you think of it :)
We recently moved to https://springdoc.org/ since SpringFox is basically dead.

Don't go OpenAPI first, go API first
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.

FLUENT
We start with an example app that will generate logs. We will use a Java API from a previous post on deploying with Helm. For the complete code for this section take a look at this branch here. We see that we have a logback.xml where we specify to write logs to a file. (See here te relevant part)
-
OAS3 AND SPRING BOOT
We will add OAS3 documentation to a Java Spring API from a previous post on Kubernetes Helm. The completed code for this post is found on github here.
-
SPRING AUTOCONFIGURE
We are going to reuse an application that we made in an earlier post (found here). It’s just a basic setup with a greetings endpoint. The code that is used is found on github here.
-
PROMETHEUS ALERTING
Now we have the architecture in place. We only need to add a Prometheus Rule for our application that triggers an alert. We build from the Spring Boot application that we deployed in the cluster in an earlier post. The configuration of this rule is done as another CRD and is found on this branch on github.

KUBERNETES AND PROMETHEUS
The full code can be found on this branch. Here are the steps I took.

GENERIC JENKINS FILE
With our library in place we can remove the pipeline config out of our Jenkins file and refer to it as follows: (or checkout the code here)

JENKINS DELOY TO KUBERNETES
To get our app running on kubernetes we need a deployment definition. Check out this branch of our test application and check deployment/deployment.yaml:

DOCKER ON JENKINS
We need an application to test our Jenkins pipeline on. Let’s take a simple Java API using Spring. Here is the application I used on github.
