title: Hibernate without Primary Key
body: <p>I making a sample application with Hibernate. My requirement is that there is no primary key on the table. I had to do only select query from application. I know there should be a primary key, but the table I am referring has been made without it.</p>
  
  <p>It has about 50k records. So, modifying the table to add ID column does not see viable option.</p>
  
  <p>Can it possible?</p>
