API First Development with Spring Boot and OpenApi 3 and Swagger | Coding Session 10 | BibBobBib

HEJA coding people, I hope you're well,
WELCOME to this small coding exercise video ;)

THANK YOU
for being here, I hope you're well!

CONTENT
Let's continue with our spring boot projects. This time I try API First approach using Spring Boot and Open API Specification 3.0 and Swagger.

For this session I created 1 simple spring boot application.
First I add sleuth and zipkin features to the both spring boot apps and trace the requests in zipkin ui. Then I let the ui-service call the data-service, to see how this communication cloud be traced in zipkin.
