Goal

Migrate from CXF using JAX-RS for API endpoints to Spring Web MVC

Description

The Console Backend currently relies on the CXF implementation of JAX-RS for handling RESTful services like the API endpoints. However, we've decided to migrate to Spring Web MVC as Spring is already being used and CXF with JAX-RS lacks proper support for things like WebSocket's or other modern web services.

Tasks

• Add Spring Web MVC as a dependency
• Run JAX-RS equivalents endpoints using Spring next to existing endpoints
• Remove JAX-RS endpoints
• Remove CXF dependencies
• Change implementations to Spring Web only

See https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-servlet/multipart.html - in spring 6, the default behavior of multipart has been changed, make sure to use setMultipartConfig and add a bean named 'multipartResolver'.
