To support the fact that we are now making an AJAX call, and not expecting a redirect, we need to make alterations on the server side.

For one thing, we need to change the image microservice's CommentController from being view-based to being a REST controller. Earlier in this book, it looked like this:

    @Controller 
    @EnableBinding(Source.class) 
    public class CommentController { 
      ... 
    } 

@Controller marked it as a Spring WebFlux controller that was expected to return the HTTP redirect.

To tweak things for AJAX calls, update it to look like this:

    @RestController 
    @EnableBinding(Source.class) 
    public class CommentController { 
      ... 
    } 

By replacing @Controller with @RestController, we have marked this class as a Spring WebFlux controller with results written directly into the HTTP response body.
