Spring MVC: Async Processing
Marten Deinum, Daniel Rubio, Josh Long · Apress eBooks · 2017
When the Servlet API was released, the majority of the implementing containers used one thread per request. This meant a thread was blocked until the request processing had finished and the response was sent to the client. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
