質問

私はJava 9上でSpring Bootアプリケーションを実行しようとしているのですが、JAXBの問題に直面し、ガイドで説明されていますが、私には動作しませんでした。JAXB apiへの依存を追加し、アプリケーションは動作するようになりました。 Javaバージョン>=9でJAXBの実装が不足しているため、以下の例外が発生した場合。 

javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.

どのように解決するのですか？

pom/gradleにこれらの依存関係を追加してください。

Gradle : 

compile('javax.xml.bind:jaxb-api:2.3.0')
compile('javax.activation:activation:1.1')
compile('org.glassfish.jaxb:jaxb-runtime:2.3.0')

Pom :
