Master Microservices with Spring Boot and Spring Cloud - Step 19 – Content Negotiation – Implementing Support for XML

The video tutorial covers content negotiation in RESTful services, focusing on how resources can have multiple representations, such as JSON and XML. Initially, the tutorial explains how to handle JSON requests and the importance of specifying accept headers. It then addresses the complexities of handling XML requests, including dealing with 406 errors when XML is not supported. The tutorial provides a step-by-step guide on adding XML support using Jackson data format XML dependency. It concludes with testing XML representation and implementing POST requests with XML data, demonstrating the successful addition of content negotiation features.
