title: Hibernate updating my entities
body: <p>I have created 2 entities. 
  Now when I retrieve my entities in my backend I verify some things, but when my backend return those entities to my frontend the hibernate try to update automatically the db. </p>
  
  <p>I don't actually run any update in my backend code (I think it`s because I change some data in my entity while i do my logic and remove some properties that I should return to my frontend). </p>
  
  <p>How can I tell to hibernate to not update anything until I run .save or .update explicitly?</p>
