contract-first-sample

A sample project for contract first approach using OAS

This project is a simple representation of contract first approach using open api specification. We have created the contract first, then generated the client and server (interface only) code using the openapi-generator-maven-plugin. We have implemented the server side code in the service code (contract-first) and then used the generated client side code in consuming the service (sample-client).
