Java-buildpack: JBPはSpringBoot 2.0をサポートしていますか？

まだテストしていませんが、実行方法（ java -jar ）が変更されていないことを考えると、変更されていないと信じる理由はありません。

私は実際に現在のM3に問題があります。 ただし、MongoDBが使用されている場合にのみ発生します。 Cloud FoundryはMongoDB接続を再構成しようとし、 NoSuchMethodErrorます。

私が見る限り、これはspring-data-mongo依存関係の重大な変更によるものです。

セットアップは、次のスターターを備えた基本的なSpring Boot2.0.0.M3アプリです。

• アクチュエータ
• データ-mongo
• ウェブ
• NS。

ええ、これは自動再構成の問題です。 SpringDataにアップグレードされたメジャーバージョンに対応する準備ができていない可能性のあるSpringCloudコネクタのバージョンに依存しています。 @scottfrederickはこれを知っていますか？私がする必要があるのは、新しいバージョンのSpring Cloud Connectorの使用を開始することだけですか？

JavaテストアプリケーションをBoot2.0に更新しています。 その作業に基づいて、問題があると思われる唯一のことは、Spring Data Mongoの自動再構成が壊れているように見えることです（APIが変更されています）。 その指標としてこの問題を開いたままにし、修正が完了したら閉じます。

これがいつ利用可能になるかについての見積もりはありますか？ また、現時点で適用可能な回避策はありますか？

配信は間近に迫っていますが、 @ scottfrederickがSpringCloudConnectorsのリリースを行うのをまだ待っています。 自動再構成を簡素化し、Spring Cloud Connector2.xを使用するようにアップグレードするための重要な作業を行いましPRを消費して、自動再構成の新しいバージョンを公開します。

MongoDBの自動再構成以外はすべて今日期待どおりに機能するため、回避策は実際には必要ありません。 MongoDBの自動再構成を実行しようとしている場合、サービスを使用するようにアプリケーションを明示的に構成する以外に回避策はありません（とにかく実行する必要があります。自動再構成は、実稼働システムには適していません）。
