从MusicBrainz Web服务检索元数据

我正在尝试使用第三方java库从MusicBrainz下载元数据： musicbrainzws2-java

我正在尝试检索指定相册中各个歌曲的元数据。 我已经检索了专辑的MBID，但是当我尝试搜索专辑中的歌曲时，我得不到回复。

这是我的代码：

public static void main (String args []) throws MBWS2Exception { String artistName = "Imagine Dragons"; String album_id = null; Artist artist = new Artist(); artist.search(artistName); List results = artist.getFullSearchResultList(); ArtistWs2 song = results.get(0).getArtist(); artist = new Artist(); song = artist.lookUp(song); List rgl = artist.getFullReleaseGroupList(); for(int i =0; i<rgl.size(); i++){ System.out.println(rgl.get(i).getTitle()); if(rgl.get(i).getTitle().equals("Night Visions")){ album_id = rgl.get(i).getId(); } } System.out.println("Night visions ID: " + album_id); Release release = new Release(); release.search(album_id); List list = release.getFullSearchResultList(); for(int i =0; i<list.size(); i++) System.out.println(list.get(i).getEntity()); 

有人可以给我一些指示。 谢谢

管理以检索信息代码如下：

 public static void main (String args []) throws MBWS2Exception { String artistName = "Imagine Dragons"; String albumName = "Night Visions"; String album_id = null; Artist artistsearch = new Artist(); artistsearch.search(artistName); List result = artistsearch.getFullSearchResultList(); ArtistWs2 artist = new ArtistWs2(); for(ArtistResultWs2 x : result){ if(x.getArtist().toString().equals(artistName)){ artist = x.getArtist(); break; } } artistsearch = new Artist(); artistsearch.lookUp(artist); List release_groups = artistsearch.getFullReleaseGroupList(); ReleaseGroupWs2 releasegroup = null; for(ReleaseGroupWs2 x : release_groups) if(x.getTitle().equals(albumName)){ releasegroup = x; } ReleaseGroup releasegroupsearch = new ReleaseGroup(); releasegroupsearch.lookUp(releasegroup); List releases = releasegroupsearch.getFullReleaseList(); ReleaseWs2 album = releases.get(0); Release releaselist = new Release(); releaselist.lookUp(album); MediumListWs2 releaselist1 = releaselist.getComplete(album).getMediumList(); List tracklist = releaselist1.getCompleteTrackList(); System.out.println("artist: " + artist); System.out.println("album: " + album); System.out.println("title: " + tracklist.get(0).getRecording().getTitle()); System.out.println("genre: " + tracklist.get(0).getRecording().getTags().get(0).getName()); System.out.println("track: " + tracklist.get(0).getPosition()); System.out.println("year: " + album.getYear()); System.out.println("disc no.: " + releaselist1.getMedia().get(0)); System.out.println("label: " + album.getLabelInfoString()); System.out.println("artist sort : " + tracklist.get(0).getRecording().getArtistCreditString()); System.out.println("comment: " + tracklist.get(0).getRecording().getDisambiguation()); } 

}
