title: MapStruct with Spring Boot, annotate generated classes with custom annotation
body: <p>Is there possibility, to annotate class generated by MapStruct, with custom annotation? Currently Im using MapStruct with <code>componentModel</code> defined as <code>"spring"</code>, like:</p>
  
  <pre><code>@Mapper(componentModel = "spring")
  public interface MyMapper {}
  </code></pre>
  
  <p>For this interface, class is generated by MapStruct:</p>
  
  <pre><code>@Component
  public class MyMapperImpl implements MyMapper {}
  </code></pre>
  
  <p>So I can easily inject it. What I want to do, is to annotate generated class with <code>org.springframework.context.annotation.Profile</code> annotation, so my generated bean will be in force only if specific profile is defined, is there possibility to inject such annotation, <code>@Profile("dev")</code>, to generated class somehow? I was thinking about <code>org.mapstruct.DecoratedWith</code> annotation, but I didn't make it working for me</p>
