SQL Server データベースを使用して Spring-Hibernate アプリケーションに取り組んでいます。デッドロックが発生しています。トランザクション属性は、Spring 構成を介して定義されます。アプリケーションには、アプリケーション コードに悲観的ロックが実装されています。ユーザーが顧客レコードで作業を開始すると、そのレコードはロックされます。トランザクションを短くしたり、トランザクションの分離レベルを変更したりすることで、ロックをなくすように取り組んできました。
別の方法として、ロックを引き起こし、デッドロックを引き起こす SQL に NOLOCK を指定して、データベース レベルのロックを排除する (型にはまらない) アプローチは実用的でしょうか?
