title: How to refresh ConcurrentMapCache periodically in Spring 4?
body: <p>If I am using <code>@Cashable</code> annotation to cache the results using a <code>ConcurrentMapCacheManager</code>, then how would I periodically refresh the cache in Spring 4.3.5? </p>
  
  <p>It looks like Ehcache provides some implementation and it depends on the backing store, but I would like to understand in case I am not using any external cache backing store.  </p>
  
  <p>One option I am thinking about is to periodically call a method, but what implementation will go into that method? How will I collect and call all those cachable methods again?</p>
  
  <p>It would be great to look at some examples.</p>
