合并许多application.properties文件而不是Spring Boot上的替换？
我正在使用Spring Booot MVC 1.2.2.RELEASE。 我有我的多模块项目，结构如下：
example-backend-development(parent) ---> example-backend-development-domain ---> example-backend-development-service 我想让两个模块独立，或者至少从服务域创建域，因为服务在其类路径中具有域模块。 因此，两个模块都将application.properties文件放在各自的资源文件夹中。 我想这样做，因为我不想处理来自服务模块的所有属性（例如，属于域模块的Jpa属性）。
例如，我在服务模块中有这个application.properties
logging.level.org.springframework.web: DEBUG logging.level.org.hibernate: ERROR logging.level.com.example.movies: DEBUG
而这一个在域模块中
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
问题是当我启动我的服务时，因为它们都是application.properties在服务类路径中，然后它将来自服务的application.properties替换为来自域的另一个。 如果它们具有相同的名称，我想合并它们，就像这种情况一样。 这里是spring的日志（DEBUG + INFO）

我搜索了很多，但我找不到任何东西。 你有什么主意吗？ 提前致谢！
假设您正在从example-backend-development-service启动应用程序，我建议您执行以下操作
将example-backend-development-domain application.properties重命名为`domainapplication.properties。 在引导您的应用程序时，覆盖属性配置，如下所示。 我测试了它，它确实对我有用。
/** * Hello world! * */ @SpringBootApplication @PropertySource(value = { "application.properties","domainapplication.properties" }) public class App { @Autowired private ModuleService moduleService; public static void main(String[] args) throws Exception { ApplicationContext applicationContext= SpringApplication.run(App.class, args); ModuleService moduleService = (ModuleService) applicationContext.getBean(ModuleService.class); System.out.println(moduleService.getProp()); String[] beanNames = applicationContext.getBeanDefinitionNames(); Arrays.sort(beanNames); for (String beanName : beanNames) { System.out.println(beanName); } } }
编辑：-
如果您也从域启动，请在此处参考中使用以下内容
如果您不喜欢application.properties作为配置文件名，则可以通过指定spring.config.name环境属性来切换到另一个。 您还可以使用spring.config.location环境属性（以逗号分隔的目录位置列表或文件路径）来引用显式位置。
$ java -jar myproject.jar --spring.config.name=myproject
要么
$ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
