Вопрос:

Я пытаюсь привязать XML к POJOs с помощью Simpleframework, но это работает некорректно, и я не могу обнаружить ошибку. Эта структура отлично работала с JAXB, я просто изменил аннотации на Simpleframework. Возможно, ошибка в List<Track> этом, но я не могу в этом разобраться.

Message.toString записывает это (заголовок отображается правильно):

 Message [body=Body [trackList=TrackList [tracks=[Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null], Track [trackId=null, trackMbid=null, trackLength=null, lyricsId=null, instrumental=null, subtitleId=null, trackName=null, albumName=null, albumId=null, artistId=null, albumCoverart=null, artistMbid=null, artistName=null]]]], header=Header [statusCode=200, executeTime=0.0075960159301758, available=1]]

Это входящий XML:

Ответ №1:

Я нашел решение. Здесь должен быть атрибут inline=true :

 @ElementList(name = "track", required = false)
public List<Track> tracks;
