Spring - Ensure Thread Pooling
<p>The question is How to ensure that we can control how many concurrent calls there can be towards any given system from Spring application?</p>

<p>Secondary how to provide such functionality? </p>

<p>Does Spring already has such mechanism?</p>

<p>I have basic knowledge about FixedThreadPool but no clue how to implement such thing.</p>

<p>'Calls' as web service calls to external systems and subsystems.
'concurrent calls' - running at the same time - I don't know if that description helps.</p>

<p>Java/Spring based enterprise application - I'm new in project so I have huge lack of information yet.</p>

<p>What I've noticed till now it uses spring in version 4.x
context, web, webmvc, core, aspects, aop, beans, orm, jdbc, context-support,</p>
