お返事ありがとうございます。私は、persistence.xmlにhibernate.dialectを追加しました。エラーが変更されました。注意：接続プロパティが指定されていないため、ユーザーはJDBC接続を指定する必要があります。 org.hibernate.dialect.Dialect INF：Dialect：org .hibernate.dialect.MySQLDialect org.hibernate.transaction.TransactionFactoryFactory buildTransactionFactory org.hibernate.transaction.JDBCTransactionFactory INFO：JNDIに工場を結合しない、何のJNDI名はJDBC接続 を供給しなければならない ___Theのユーザーが ++ヌルをERRS設定されていません –

@rym、更新persistence.xmlとhibernate.cfg.xmlファイルを見てみたいと思います。 –
@rym、なぜhibernate-cfg.xmlとpersistence.xmlファイルが同時に必要なのかわかりません。私が答えて述べたように、persistence.xmlファイルのhibernate.dialectプロパティを設定することができます。使用するプロパティ名は "javax.persistence。*"スペースではないため、該当する場合は選択されます。 hibernate-cfg.xmlファイルを削除するのは安全だと思いますが、これは目的を果たさないためです。 –
