Springブート1.4.xに必要な最小Javaバージョン

Question

私はSpringブート1.4.xを使用してWebサービスを開発しており、Java 6をサポートするWebsphere 8.5に展開しています。しかし、WASで戦争を展開すると、エラー。

スプリングブートのjar依存関係（spring-ws-core-2.3.1.RELEASE.jar）のように見えますが、Javaでコンパイルされたクラスがあります。以下のエラーが発生しています。

Spring Boot 1.4.xを使用するために必要な最小Javaバージョンは何ですか？ 私の場合、上記の依存関係だけを下位バージョンに上書きすることは可能ですか？

According to the reference documentation：

By default, Spring Boot 1.4.4.RELEASE requires Java 7 and Spring Framework 4.3.6.RELEASE or above. You can use Spring Boot with Java 6 with some additional configuration. See Section 81.11, “How to use Java 6” for more details. Explicit build support is provided for Maven (3.2+) and Gradle (1.12 or 2.x). Support for Gradle 2.8 and earlier is deprecated. Gradle 3 is not supported.

あなたが問題を抱えている依存性は春ブーツではなく、別のSpring Web Services which is only compatible with Java 7：

Spring Web Services requires a standard Java 7 Runtime Environment. Java 8 is also supported. Spring-WS is built on Spring Framework 4.0.9, but higher versions are supported.

あなたは依存関係をダウングレードまたは除外しようとすることができますが、あなたが何かを壊す危険性が高いがあります。
