Ich habe ein Spring-Boot-Projekt, das ich in IntelliJ erfolgreich ausführen kann, aber wenn ich eine ausführbare JAR-Datei packe, kann ich es nicht mehr ausführen. Hier ist der Stack-Trace der Ausnahme:

18:13:55.254 [main] INFO  o.s.c.a.AnnotationConfigApplicationContext - Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@b3d7190: startup date [Wed Sep 07 18:13:55 CEST 2016]; root of context hierarchy

Meine Konfiguration sieht ungefähr so aus:

@Configuration
@EnableAutoConfiguration
public class AppConfig {
  ... some beans
}

Ich habe hinzugefügtMETA-INF/spring.factories unter dem Projektressourcenordner wie in @ beschrieb 43.2 Kandidaten für die automatische Konfiguration finden wie folgt Aber das hat das Problem nicht behoben:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
el.dorado.AppConfig
