How to control how many threads in a Spring application?

Is it important, or even possible, to control how many threads Spring uses in, for example, a web application?

Lets say I have a Spring based REST server. Should I, or is it possible to control the number of threads Spring uses to service requests? If I deploy my app on a machine with 8 cores vs 4, should I have to configure Spring to account for the difference in cores?

The number of request threads is controlled by the web container not by Spring. For example, if you are running on Tomcat, this Q&A explains how to configure the thread pool size: https://stackoverflow.com/a/7803226/139985

It is possible, but you should generally shouldn't. Let the container deal with this ... unless you have good (evidence-based!) reason to think that the container is making a poor choice. The container defaults / policy should take account of the number of available cores.
