title: Run Spring class asynchronously
body: <p>I'm working in an Spring application that downloads data from different APIs. For that purpose I need a class Fetcher that interacts with an API to fetch the needed data. One of the requirements of this class is that it has to have a method to start the fetching and a method to stop it. Also, it must download all asynchronously because users must be able to interact with a dashboard while fetching data.</p>
  
  <p>Which is the best way to accomplish this? I've been reading about task executors and the different annotations of Spring to schedule tasks and execute them asynchronously but this solutions don't seem to solve my problem.</p>
