Windows サービスとして tanuki サービス ラッパーで Camel (Spring ベース) プロジェクトを実行しようとしています。統合方法 #1 と #2 の両方を試しました: WrapperSimpleApp、WrapperStartStopApp の両方で、次の動作が発生しました。
Camelは正常に起動し、すぐにラッパーがシャットダウンしました!
最初は、これは Camel の非デーモン スレッドに関係しているのではないかと疑っていましたが、統合メソッドと org.tanukisoftware.wrapper.WrapperStartStopApp.systemThreadCount システム プロパティをいじってみると、ラッパーが JVM をシャットダウンする別の理由があるに違いないことに気付きました。
誰かが理由を知っていますか？
これがラッパーと Camel ログです - 2 行目と 3 行目に注意してください:
