私はIntelliJから正常に実行できるSpringブートプロジェクトを持っていましたが、実行可能なjarをパッケージ化するともう実行できません。ここでは、例外のスタックトレースです:設定クラスのインポート候補を処理できませんでした

私の設定のようなものです:
@Configuration
@EnableAutoConfiguration
public class AppConfig {
... some beans
}
43.2 Locating auto-configuration candidatesで説明したように、次のように私は、プロジェクトのリソースフォルダの下META-INF/spring.factories
を追加しました。しかしこれはしませんでした問題を修正:
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
el.dorado.AppConfig
は、プロジェクトpom.xml
です

Bootがこの 'AppConfig'を最初にスキャンするためには、あなたの*エントリーポイント*設定クラスに' @ EnableAutoConfiguration'が必要です。 – chrylis
SpringBootApplicationクラスとpom.xmlを共有できますか? –
これは奇妙な設定です。自動構成クラスに '@ EnableAutoConfiguration'を入れてはいけません。参照したドキュメントを確認してください。第二に、クラスパス上で 'spring-boot-autoconfigure'なしであなたのアプリを動かそうとしているようです。 'spring.factories'が見つかりませんので、ビルドでは正しくパッケージ化されません。問題を再現するプロジェクトを共有してください。 –
