Spring Bootフレームワークを使用したWebアプリケーションでエラーが出る

Q&A

Closed

Java初心者DockerWebアプリケーションSpringBoot

解決したいこと

デプロイしたWebアプリケーションが正常に動作するようにしたい。

AmazonなどのECサイトに自分が出品している商品を管理するWebアプリを作っています。
Eclipse上で実行すると正常に動作しますが、デプロイ後、「localhost:8080/App名/」にアクセスしてもWhitelabel Error Pageが表示されてしまいます。
解決方法を教えていただけませんでしょうか。

当方初心者のため、情報に不足等あるかと思いますので、ぜひご指摘いただけますと幸いです。

言語：Java (jdk20)
フレームワーク：SpringBoot(ver.3.1.2) + Thymeleaf
ORマッパー：Mybatis
ビルド：Gradle
IDE：Eclipse
デプロイ環境(ローカル)：Docker(Ubuntu)　tomcatコンテナを立てて.warファイルを配置
tomcat：10.1-jdk21

発生している問題・エラー

エラーが発生した際のDocker Logsを添付します。

エラーの内容からロジックというよりは、依存関係やJavaのバージョンなどの問題ではないかと考えました。
念のため、build.gradleの内容を記載します。

自分で試したこと

①どのファイルに問題があるのかを切り分けるため、新規プロジェクトを作成し、ファイルを一つずつ移してデプロイし、正常に動作するかを検証
　・entity、resources(html,cssなど)、controllerはすべてに問題がないことを確認
　・Service、DAOの一部は問題ないことを確認しているが、まだすべてを切り分けられていない(対応中)
②Dockerのtomcatのバージョンを変えて正常に動作するかを確認
　・ver.9 以下はSpringBoot ver.3 以上非対応(？)のため、ver.10以上に変更
　・10.1-jdk17でデプロイ後実行すると404エラーが発生
③build.gradleの依存関係で指定していたjackson-databaindのバージョンを2.12.5に変更⇒エラー解消なし
　バージョン指定削除(SpringBootデフォルト利用)⇒エラー解消なし
