Hello.
When I used Multibinder and MapBinder at the same time, I encountered
a strange result.
I wrote the following code in order to add a FlickrPhotoSummarizer
object into Set and Map.
protected void configure() {
Multibinder<UriSummarizer> uriBinder =
Multibinder.newSetBinder(binder(), UriSummarizer.class);
uriBinder.addBinding().to(FlickrPhotoSummarizer.class);
MapBinder<String, UriSummarizer> uriMapBinder =
MapBinder.newMapBinder(binder(), String.class,
UriSummarizer.class);
uriMapBinder.addBinding("flickr").to(FlickrPhotoSummarizer.class);
//
A
}
So, Set<UriSummarizer> was injected to the following class.
public class ClientWithMultibinder implements Client {
private Set<UriSummarizer> summarizers;
@Inject
public ClientWithMultibinder(Set<UriSummarizer> summarizers) {
this.summarizers = summarizers;
}
........
}
I expected that summarizers shoud have only one FlickrPhotoSummarizer
object. But it had two.
I commented out "A" line on trial, and it had one.
I can't understand what happened.
I hope sombody helps me.
Thank you for your reading my awkward English.
