title: How to know which framework is used?
body: <p>I have been made to involve recently in a new project and I am completely unaware of which framework is used.After a long time I came to know spring is used because I saw some imports like</p>
  
  <pre><code>import org.springframework.beans.factory.annotation.Configurable; 
  </code></pre>
  
  <p>and I am sure spring is used.Now I am completely unaware of whether hibernate is used or jpa is used.When I asked my colleague then some are telling jpa is used and some are telling hibernate that means they are also confused.Can any body please throw some light regarding this.How would I know jpa or hibernate is used.</p>
  
  <p>which packages should be imported specifically for jpa or hibernate.Any hint please</p>
