Maven is a great build tool which is very prominent in Java community. It helps developers in their java projects in defining the project dependencies which is required during development. It also serves an important purpose of creating the build of the project in an automated way once configured in the pipeline.
SpringBoot helps developers to quickly create production grade application which is based on Spring framework. It removes the overhead of a lot of boilerplate code and allow developers to focus on business task in need. With very few lines of code you can easily expose a REST endpoint.
OpenAPI specification allows developers to perform API first approach. In API first approach, you define the API endpoints and their contract like input type they will receive and the type of output they will provide. Using the specification, you can proceed with generating the actual code needed to expose such endpoints from your application.
Hope you get the idea of the three components and in the below video I have demonstrated how we can create a blank maven project, upgrade it to SpringBoot3 project and finally create endpoint using OpenAPI specification.
