Rationale

This project aims to show the problems we are facing with logging and tracing when upgrading to spring boot 3 in a reactive environment using netty.

Getting started

Build

The 'main' branch contains the functioning spring-boot-2 version including tests that show our expectations.

mvn clean install

Running the application locally

To locally run the application, use the following command:

mvn spring-boot:run

For local tests, a mockserver can be started with the provided docker-compose file. It simulates a backend-service, that will be accessed by our application.

docker-compose -f ./docker/docker-compose.yaml up

The mockserver can be reached via http://localhost:1080 and exposes a dashboard to monitor all requests is available via Mockserver Dashboard.

This application exposes a gateway route that can be called with

curl http://localhost:8080/question-route

This application exposes a REST endpoint that can be called with

curl http://localhost:8080/question-controller
