title: Use repository method in custom repository
body: <p>I check documentation of spring for doing custom method</p>
  
  <pre><code>interface UserRepositoryCustom {
    public void someCustomMethod(User user);
  }
  
  class UserRepositoryImpl implements UserRepositoryCustom {
  
    public void someCustomMethod(User user) {
      // Your custom implementation
    }
  }
  </code></pre>
  
  <p>What is need to do if i need to use some standard rempository method (find, delete...) in UserRepositoryImpl?</p>
