merge many application.properties files instead of replace on Spring Boot?
提问by jscherman
i am using Spring Booot MVC 1.2.2.RELEASE. I have my multi-module project which is structured like this:
我正在使用 Spring Boot MVC 1.2.2.RELEASE。我有我的多模块项目，其结构如下：
example-backend-development(parent)
---> example-backend-development-domain
---> example-backend-development-service
I want to make both modules independent, or at least domain from service, since service has domain module in its classpath. So both modules have their application.properties file in their respective resources folder. I want to do it like this way because i don't want to handle all properties from service module (e.g Jpa properties, which belongs to domain module).
我想让两个模块独立，或者至少是域独立于服务，因为服务在其类路径中有域模块。所以这两个模块在各自的资源文件夹中都有它们的 application.properties 文件。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 Jpa 属性，它属于域模块）。
So for example i have this application.properties in service module
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
And this one in domain module
域模块中的这个
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
The problem is that when i boot my service, as they both application.properties are in the service classpath, then it replace the application.properties from service with the other one from domain. And i want to merge them if they have the same name, as this case. Here the spring logs (DEBUG+INFO)
问题是，当我启动我的服务时，因为它们两个 application.properties 都在服务类路径中，然后它将 service 中的 application.properties 替换为域中的另一个。如果它们具有相同的名称，我想合并它们，就像这种情况。这里是弹簧日志（DEBUG+INFO）

I searched a lot but i couldn't find anything. Do you have any idea? Thanks in advance!
我搜索了很多，但找不到任何东西。你有什么主意吗？提前致谢！

Assuming You are booting your application from example-backend-development-service, I would suggest doing the following
假设您正在从 启动您的应用程序example-backend-development-service，我建议您执行以下操作
Rename application.propertiesin example-backend-development-domainto `domainapplication.properties. While Booting Your application, Override the property configuration as shown below. I tested this and it does work for me.
重命名application.properties在 example-backend-development-domain为`domainapplication.properties。在引导您的应用程序时，覆盖属性配置，如下所示。我对此进行了测试，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);
}
}
}
EDIT:-
编辑：-
If you are booting from domain as well just use the following in the referencehere
如果您也从域启动，只需在此处的参考中使用以下内容
If you don't like application.properties as the configuration file name you can switch to another by specifying a spring.config.name environment property. You can also refer to an explicit location using the spring.config.location environment property (comma-separated list of directory locations, or file paths).
如果您不喜欢 application.properties 作为配置文件名，您可以通过指定 spring.config.name 环境属性切换到另一个。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）引用显式位置。
$ java -jar myproject.jar --spring.config.name=myproject
or
或者
$ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties
