Answer 1

Alternatively you should be able to configure kind of properties repository bean and then use it in SpEL directly in @Value annotation.

Let's say you'd have bean called propertiesRepository in your context that implements following interface:

interface PropertiesRepository {
    String getProperty(String propertyName);
}

then on bean where you want to inject values you can use following expression

@Value("#{propertiesRepository.getProperty('my.property')}")
String myProperty;
