合并许多 application.properties 文件，而不是在 Spring Boot 上替换？

java spring spring-mvc jpa spring-boot
2022-09-02 21:28:29

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

我想使这两个模块独立，或者至少是与服务的域，因为服务的类路径中有域模块。因此，这两个模块都在其各自的资源文件夹中都有其 application.properties 文件。我想像这样做，因为我不想处理服务模块中的所有属性（例如Jpa属性，它属于域模块）。

例如，我在服务模块中有这个应用程序.属性

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

而这个在域模块中

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，因为它们都位于服务类路径中，因此它将服务中的 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，就像这种情况一样。此处为弹簧日志（调试+信息）

我搜索了很多，但我找不到任何东西。你有什么想法吗？提前致谢！


答案 1

假设您正在从 引导应用程序，我建议执行以下操作example-backend-development-service

重命名为'domainapplication.properties。引导应用程序时，重写属性配置，如下所示。我测试了这个，它确实对我有用。application.propertiesexample-backend-development-domain

 /**
     * 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：-

如果您也从域引导，只需在此处的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配置文件。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

或

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