J'ai un problème avec l'injection d'un haricot @Inject ou @Autowired annotations: cela est arrive dans une classe appelée MultitenantConfiguration: pendant deployement mon Tomcat 8 bloquer et arrêter! Cela se produit uniquement lorsque l'application est déployée sur tomcat, pas quand pom packaging = jar (donc il fonctionne comme application autonome avec Tomcat embarqué car c'est l'application de démarrage de Spring) .. Notez que FileProperties les accessoires restent null et je reçois NullPointerException en ligne avec le code files = Paths.get(props.getTenantsFilePath()).toFile().listFiles(); .. beacuse propr est null .. Pourquoi? Que puis-je faire .. Ce sont des lignes de mon code:Erreur injection de configuration Bean dans un autre bean en utilisant SpringBootServletInitializer dans Tomcat88

je résous, semble que @ Injecter ne fonctionne pas, remplacez donc tous @ Injecter avec @ Autowired. Je pense que parce que cdi-api dans pom a une portée \t fourni .. –

'@ ConfigurationProperties' ne fonctionne que pour les propriétés de lecture Spring Boot. Les '@ PropertySource' sont lus trop tard et ne seront pas liés (d'où le' NullPointerException'). Supprimez le '@ Configuration' mettre les propriétés dans le' application.properties' et ajouter un @EnableConfgurationProperties (FileProperties.class) 'à votre classe d'application. –
