Android プロジェクトでは、Spring REST lib を使用して、Apache Tomcat/7.0.32で jax-rs サービスを呼び出しています。データベース通信にはhibernate 3.0を使用しています。

API がエラーを返すことがあります: org.hibernate.exception.JDBCConnectionException: could not execute query

問題は hibernate SessionFactoryにあると思います。

エンタープライズ環境で使用する tomcat Web サービスを構成する方法を知りたいです。より多くのリクエストを処理するために hibernate SessionFactory を構成する方法。

ドキュメントで提案されているように、JTA を使用できます: http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/architecture.html#architecture-current-session

「よりエンタープライズ」なものを探している場合は、SessionManager と接続プーリングを使用することをお勧めします。これにより、アプリケーションにより多くのオプションと柔軟性がもたらされます。この点に関して、Spring はいくつかの優れた機能を提供します。

乾杯、
