私は、他の戦争に依存する戦争でMavenマルチモジュールを使用しています。
Spring Boot webapp は、html ファイルのみを提供する基本的な webapp に依存しています。
Spring Boot アプリを実行すると、メインの webapp (Spring Boot のもの) からサービスと html にアクセスできますが、依存関係 war (404) から html ファイルにアクセスできません。しかし、これらの html ファイルは、Spring Boot webapp war で適切にパッケージ化されています...
問題を示すプロジェクトは次のとおりです:
https://github.com/cthiebault/spring-boot-war-overlays
このプロジェクトには 2 つの war モジュールがあります。
- dependency-webapp : html のみを提供する基本的な webapp (/dependency/index.html)
- main-webapp : Spring Boot webapp (Spring Guides gs-serving-web-contentからコピー)。この webapp は、dependency-webappに依存しています。
main-webapp pom.xml は次のとおりです。

Web アプリケーションを実行します。
mvn install
cd main-webapp
mvn spring-boot:run
編集 1: HTML ページにアクセスしようとしたときのログは次のとおりです。
