In this tutorial, we’ll see how to send scheduled messages from a server to the browser using WebSockets. An alternative would be using Server sent events (SSE), but we won’t be covering that in this article.

Spring provides a variety of scheduling options. First, we’ll be covering the @Scheduledannotation. Then, we’ll see an example with Flux::interval method provided by Project Reactor. This library is available out-of-the-box for Webflux applications, and it can be used as a standalone library in any Java project.

Also, more advanced mechanisms exist, like the Quartz scheduler, but we won’t be covering them.
