Return single property with spring-boot repository
<p>Today I use spring-data-jpa to create my queries.<br>
Is it possible to return only one property from the object?<br>
For example:</p>

<pre><code>public interface UsuarioRepository extends MongoRepository&lt;Usuario, String&gt; {

    String findNameByMailAndPassword(String mail, String pass);

}
</code></pre>

<p>I want to return only the name, not the whole <code>Usuario</code> object.</p>
