Spring data : CrudRepository's save method and update
<p>I wanted to know if the <code>{save}</code> method in <code>CrudRepository</code> do an update if it finds already the entry in the database like : </p>

<pre><code>@Repository
public interface ProjectDAO extends CrudRepository&lt;Project, Integer&gt; {}

@Service
public class ProjectServiceImpl {

@Autowired private ProjectDAO pDAO;

public void save(Project p) { pDAO.save(p); } }
</code></pre>

<p>So if I call that method on an already registred entry, it'll update it if it finds a changed attribute ?</p>

<p>Thanks.</p>
