title: Spring @Cacheable default TTL
body: <p>I generally use the <code>@Cacheable</code> with a cache config in my spring-boot app and set specific TTL (time to live) for each cache.</p>
  
  <p>I recently inherited a spring boot app that uses <code>@Cacheable</code> without explicitly stating a cache manager and ttl. I will be changing it to be explicit.</p>
  
  <p>But I am not able to find out what are the defaults when there is nothing explicit.</p>
  
  <p>I did look at the <a href="https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/cache/annotation/Cacheable.html" rel="noreferrer">docs</a> but found nothing there</p>
