私は複数の人がいる学校のプロジェクトに取り組んでいます。 私は私のプロジェクトを実行すると、これによって引き起こされるようなエラーの束を得ます： 'hibernate.dialect'が設定されていない場合、DialectResolutionInfoへのアクセスをnullにすることはできません。'hibernate.dialect'が設定されていないと、DialectResolutionInfoへのアクセスがnullになることはありません

これが私のpom.xmlである：ここ

が、これは行方不明dependencysによって引き起こされる問題ですか？ 私はJavaを使った新人です。私は自分で問題を見つけることができません。

このエラーは、アプリケーションがデータベース接続を確立できないというヒントになる可能性があります。

明示的にhibernate.dialectプロパティを設定していない場合、Hibernateはデータベース接続を介して方言を決定しようとしています。データベースへの接続が不可能な場合は、DialectFactoryImpl#determineDialectを呼び出すとnullのパラメータがDialectResolutionInfoSourceになります。

あなたのデータベースパラメータは、url、user、passwordのように正しいですか？ エラーが発生する前に、tomcatログに次のようなログエントリがありますか？

WARN org.hibernate.engine.jdbc.internal.JdbcServicesImpl [thread1] - HHH000342: Could not obtain connection to query metadata : An attempt by a client to checkout a Connection has timed out.

これは私のプロジェクトまたはデータベースのプロパティですか？ netbeansで検索すると、hibernate.dialectの関係は見つかりません。 –

あなたは正しいです。 –

それはあなたのために働いており、あなたはもはや例外を取得していないのですか？ – danielnelz
