title: hibernate @GeneratedValue correct?
body: <p>I set my entity property </p>
  
  <pre><code>@GeneratedValue
  Long id;
  </code></pre>
  
  <p>and I able to generate id for the entity in database. My question is why all the entities are sharing the same incremental number?  <strong>aren't each table should start counting from zero?</strong></p>
