title: Get physical column value with entity property value using hibernate
body: <p>I have a table T with columns defined as usual.</p>
  
  <pre><code>@Entity
  @Table(name="T")
  public class T {
  @Column(name="test_id")
  private Long testId;
  
  }
  </code></pre>
  
  <p>Given entity property "testId", I want to get corresponding DB column name (i.e. "test_id"). How could it be achieved?</p>
  
  <p><strong>Edit 1:</strong>
  I want to keep this column at separate location with actual DB column name (test_id) than testId. I fetched these values from DB using HQL which have key as entity name (i.e. testId) and I want actual column name in DB.</p>
