Salut,

J'ai eu a faire exactement le meme genre de classe via Spring pour rabbitMQ.
Ma classe comportait le code suivant dans la classe de configuration, je t'invite donc a l'essayer.
Biensur n'oublie pas de remplacer le path du fichier de configuration par celui qui te correspond.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 @Bean
    public static PropertySourcesPlaceholderConfigurer placeHolderConfigurer() throws IOException {
        PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
        propertySourcesPlaceholderConfigurer.setIgnoreResourceNotFound(true);
        propertySourcesPlaceholderConfigurer.setIgnoreUnresolvablePlaceholders(true);
        propertySourcesPlaceholderConfigurer.setLocations(new PathMatchingResourcePatternResolver()
                .getResources("file:" + System.getenv("CONF_DIR") + "/luProperties.properties"));
        return propertySourcesPlaceholderConfigurer;
    }

problem @Value pour l'injection
