@MountedPathでページにアクセスすると、@SpringBeanが動作しません。

SpringBoot 1.5.xでcom.giffing.wicket.spring.boot.starter.wicket-spring-boot-starterを使用しています。残念ながら、@SpringBean注釈を使用してSpring beansの注入を使用するとエラーが発生します。（私は家庭、第一ページ、第二ページでwicketの共通デモを使用しています）一般的なURLを使用してページにアクセスすると、その作業（bean injection）はうまくいきます：/wicket/bookmarkable/app.wicket.pages.FirstPage。しかし、このページには@MountPathアノテーションもあります。このアノテーションで定義されているURLを使ってページにアクセスすると、以下のようなエラーが出ます。 @MountPathページのSpringインジェクションを有効にする特定のオプションはありますか？ Btw。私は最新の安定したwicket-spring-boot-startter 1.0.6バージョンを使用しています（Wicket 8M5を使用した2.0.1バージョンと同じ問題）...何が間違っていますか？@MountedPathでページにアクセスすると、@SpringBeanが動作しません。

spring-boot-devtoolsを使用していますか？それを取り出してもう一度試すことはできますか？ – meleagros

本当にDevToolsを無効にすると正しく動作します。どういう意味ですか？ DevToolsは開発のために必要なツールです... –

問題は、Spring Boot Devtoolsの再起動機能です。 wicketライブラリのクラスローディングの問題があります。 @MountPathアノテーションを完全にサポートするための修正を提供します。 [Springブートリファレンス]（http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-customizing-classload） – meleagros

あなたは次の内容のルートクラスパスにMETA-INF/spring-devtools.propertiesファイルを追加する必要があります。

restart.include.wicket-annotation=/wicketstuff-annotation-[\\w-\.]+\.jar 
restart.include.wicket-spring=/wicket-spring-[\\w-\.]+\.jar

これはWicketのクラスをリロードする春ブーツデベロッパーツールに指示します再起動後に定義されたjarファイルに保存されます。

私はWicket Spring Boot Starterプロジェクトを更新します。次のリリースでは、このプロパティをもう提供する必要はありません。
