Answer 1

It depends on how you want to use the properties, if it is to inject the properties using ${propertyname} syntax, then yes just having PropertySourcesPlaceHolderConfigurer will work, which internally has access to the PropertySources registered in the environment.

If you plan to use Environment directly, using say env.getProperty(), then you are right - the properties using PropertySourcesPlaceHolderConfigurer are not visible here. The only way then is to inject it using Java code, there are two ways that I know of:

a. Using Java Config:

@Configuration
@PropertySource("classpath:/app.properties")
public class SpringConfig{

}

b. Using a custom ApplicationContextInitializer, the way it is described here
