, bir problem.I ArticleServiceImp.java kullanmak karşılaştı Verilerimi güncellemek için. Çalışmıyor. o kamu boolean updateArticle içinde (Madde makalesi) olduğunda söz veriyorum, makale
. ben yazınca ben it.and var s = 1 yazdırmak want.bacause budur Ve sorun olduğunu düşünüyorum Article.xml.
ben hava it.So kimse? thx.
bana yardımcı olabilir Ve istisna yoktur çözmek için çok zaman kullanılır. ArticleDao.xml içinde
Bir istisna alır mıyım, yoksa verilerin güncellenmesi alamadım sadece budur ait değişkeni değiştirmeyi deneyin? –
no exception.just çalışmıyor – jack
Bu bir longshot, ancak başlık durumunu kontrol edin. Bir vaka duyarlılığı sorunu olabilir. –
