私は、既存のWebプロジェクトをサポートすることを目的としたアプリケーションの開発を始めたばかりです。したがって、ビジネス層と永続性層はすでに存在し、そのWebアプリケーション内で非常にうまく機能しています。コンソールアプリケーションで両方のレイヤーのライブラリを使用すると、JpaTransactionManagerがentityManagerFactoryを必要とするというエラーが発生します。これは、Webアプリで例外がスローされないため、奇妙なことです。コンソールアプリケーションで行うのは、アプリケーションコンテキストを作成することだけです
public static void main(String[] args) {
ApplicationContext ctx = new ClassPathXmlApplicationContext("engine-context.xml");
}
engine-context.xml：
<import resource="business-context.xml" />
<import resource="persistence-context.xml" />
<tx:annotation-driven transaction-manager="myTxManager" proxy-target-class="true"/>

Webアプリケーションで行うのは、web.xmlでコンテキストXMLファイルを定義することだけです。
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/applicationContext.xml
classpath:persistence-context.xml
classpath:business-context.xml
</param-value>
</context-param>
applicationContext.xmlにはこれ以上の魔法はありません

より多くの情報が必要ですか？
汚い回避策として、新しい永続コンテキストを作成し、代わりにこれを使用しましたが、混乱を招き、冗長な構成は必要ありません。また、例外がスローされないことを除いて、スタンドアロンアプリと同じことを行う2番目のWebアプリを作成しました。
前もって感謝します。
