spring-boot - Spring boot, use profiles to load files

Question

I have used spring-boot profiles to change property values for different environments, now I want to use the same approach to load different resource files, ie example I have dev_queries and prod_queries.xml with sql queries.

How can I make spring-boot load dev_queries.xml if active profile is dev and prod_queries.xml otherwise. I know that I can check the active profile but my idea is to do not add specific logic for handle this situation.

将文件名外部化为自定义属性（docs，尤其是24.4）是否有帮助？因此，在您的属性中，您将使用：

# application-dev.properties
myapp.query-source=dev_queries.xml

# application-production.properties
myapp.query-source=prod_queries.xml

在您的应用程序 bean 中，可以使用@Value注释访问此设置：

@Value("${myapp.query-source}")
private String querySource;  // will be dev_queries.xml or prod_queries.xml

这样，在您加载 xml 文件的代码中，您不必有条件地检查当前活动的配置文件，但可以将该设置外部化到属性中。
