Master Java Web Services and REST API with Spring Boot- 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 the default use of JSON and the challenges of requesting XML, which results in a 406 error due to unsupported formats. It then guides on adding XML support by incorporating the Jackson data format XML dependency. The tutorial demonstrates testing XML representation through GET and POST requests, ultimately enabling both JSON and XML formats for resources.
