fusionner de nombreux fichiers application.properties au lieu de remplacer lors de Spring Boot?

J’utilise Spring Booot MVC 1.2.2.RELEASE. J’ai mon projet multi-module qui est structuré comme ceci:

example-backend-development(parent) ---> example-backend-development-domain ---> example-backend-development-service

Je veux rendre les deux modules indépendants, ou au moins domaine de service, car service a un module de domaine dans son classpath. Les deux modules ont donc leur fichier application.properties dans leur dossier de ressources respectif. Je veux le faire comme ceci parce que je ne veux pas gérer toutes les propriétés du module de service (par exemple, les propriétés Jpa, qui appartiennent au module de domaine).

Donc, par exemple, j’ai cette application.properties dans le module de service

 logging.level.org.springframework.web: DEBUG logging.level.org.hibernate: ERROR logging.level.com.example.movies: DEBUG

Et celui-ci dans le module de domaine

 spring.datasource.driverClassName=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://localhost:3306/sarasa_db spring.datasource.username=root spring.datasource.password=mypassword spring.jpa.hibernate.ddl-auto=update spring.jpa.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect spring.jpa.show-sql=true

Le problème est que lorsque je démarre mon service, comme ils sont tous deux application.properties dans le classpath du service, ils remplacent alors application.properties du service par l’autre du domaine. Et je veux les fusionner s’ils portent le même nom, comme dans ce cas. Ici les grumes de spring (DEBUG + INFO)

J’ai beaucoup cherché mais je n’ai rien trouvé. Avez-vous une idée? Merci d’avance!

En supposant que vous démarrez votre application à partir de example-backend-development-service , je vous suggère de procéder comme suit

Renommez application.properties dans example-backend-development-domain en `domainapplication.properties. Lors du démarrage de votre application, remplacez la configuration de la propriété, comme indiqué ci-dessous. J’ai testé cela et cela fonctionne pour moi.

  /** * Hello world! * */ @SpringBootApplication @PropertySource(value = { "application.properties","domainapplication.properties" }) public class App { @Autowired private ModuleService moduleService; public static void main(Ssortingng[] args) throws Exception { ApplicationContext applicationContext= SpringApplication.run(App.class, args); ModuleService moduleService = (ModuleService) applicationContext.getBean(ModuleService.class); System.out.println(moduleService.getProp()); Ssortingng[] beanNames = applicationContext.getBeanDefinitionNames(); Arrays.sort(beanNames); for (Ssortingng beanName : beanNames) { System.out.println(beanName); } } }

MODIFIER:-

Si vous démarrez à partir de domaine également, utilisez les éléments suivants dans la référence ici

Si vous n’aimez pas application.properties comme nom de fichier de configuration, vous pouvez en changer en spécifiant une propriété d’environnement spring.config.name. Vous pouvez également faire référence à un emplacement explicite à l’aide de la propriété d’environnement spring.config.location (liste d’emplacement de répertoires ou de chemins de fichiers séparés par des virgules).

 $ java -jar myproject.jar --spring.config.name=myproject

 $ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
