次の号で久しぶりに電話を切りました。私は一対多の関係を持っており、Hibernate を使用してモデルに従ってデータベースを生成しています。次のエラーが発生します。しかし、私はそれを正しく行っているようで、何も問題はありません。そして、AppFuse を使用して生成されたアプリを使用しています。
Field 'task_id' doesn't have a default value
org.hibernate.exception.GenericJDBCException: could not execute statement
これが私の2つのモデルです。

この特定の質問に対するすべての答えは AUTO_INCREMENT に関係していましたが、すべて持っていますが、まだ機能していません。どんな助けでも大歓迎です。
