Note: it's important to understand that several Spring projects are offering different OAuth-related features and implementations. In addition, the new client is a reactive, non-blocking solution that works over the HTTP/1.1 protocol. It was created as part of the Spring Web Reactive module and will be replacing the classic RestTemplate in these scenarios.

serving a simple Foo object secured resource accessible using the /foos/ endpoint Simply put, WebClient is an interface representing the main entry point for performing web requests.

The WebClient object addresses the complexity of the HttpWebRequest by wrapping it to provide a simpler interface for calling RESTful services. Note that you must have read the whole response before you can send a new request to the server. We won't go over the full configuration, since it's not the topic of this tutorial, so it's enough knowing that: An intrinsic part of the modern web application is the ability to use external APIs and webpages. To better understand the role of the OAuth2 Client, we can also use our own servers, with an implementation available here. We can use well-known authorization providers, like Google or Github. In line with the OAuth2 specification, apart from our Client, which is the focus subject of this tutorial, we naturally need an Authorization Server and Resource Server.
