現在、データベースとしてcassandraを使用したスプリングブートを使用してアプリケーションを開発中です。トランザクション管理によるスプリングブートエラー
私はカッサンドラクラスターを初期化するクラスを作成しました。私のDAOレイヤクエリメソッドで@Transactionalの使用を開始するとすぐに問題が始まります。システムでは以下のエラーメッセージを使用することを許可していません -
An exception has occured in method getMdoBean with msg: No qualifying bean of type 'org.springframework.transaction.PlatformTransactionManager' available.
私は間違っていることを理解していません。私のアプリは、トランザクション管理に関連する問題なしに、春のブートなしで正常に動作します。
H2データベースとともにJPAサポートを追加しようとしましたが、問題が解決しました。私は宿題をして、H2データベースとそのメモリ内データ記憶メカニズムについて読んでいました。私は、TransactionManagementの問題がどのように修正されているのか理解できません。それは世話をしているH2データベースドライバのためですか？
第2に、私はH2データベースを必要としないため、この解決法は私にとっては良いとは思われません。バックエンドは私のアプリケーションのためのカサンドラです。どんな導線が役に立つでしょう。ありがとう！キャッシングのための

メソッドレベルで上記のクラスで@Transactionalを使用すると、JPAのH2サポートを追加しないと許可されません。 POMのコード行の下に置いてもうまくいきます。
