NoClassDefFoundError：クラスを初期化できませんでした.... utils.HibernateSessionFactory

Question

助けてください。 psvmクラスでセッションを実行するとセッションが完璧に動作します。しかし、それがtomcatで実行されるとき：tomcatはこの例外を表示します。

Tomcat例外：ハンドラの処理に失敗しました。ネストされた例外がjava.lang.NoClassDefFoundErrorがある：クラスru.haki.utils.HibernateSessionFactory

Answer 1

コアに含まれているため、Hibernate Annotations依存関係を削除して解決しました。

Answer 2

あなたにも、Tomcatのライブラリ内の休止状態のjarファイルを含める必要があります。 NoClassDefFoundErrorは、ほとんどの場合、jarファイルが見つからない場合に発生します。
