How to programmatically resolve property placeholder in Spring

Question

I currently work on a web application based on Spring 3.1.0.M1, annotations based, and I have a problem with resolving property placeholders in one specific place of my appl

Answer 1

One option is to add a PropertySource (here MapPropertySource to exemplify an in-memory configuration) to a ConfigurableEnvironment and ask it to resolve properties for you.

public class Foo {

    @Autowired
    private ConfigurableEnvironment env;

    @PostConstruct
    public void setup() {
        env.getPropertySources()
           .addFirst(new MapPropertySource("my-propertysource", 
               ImmutableMap.of("your.property.name", "the value")));
        env.resolvePlaceholders("your.property.name");
    }
}

Optionally annotate the Foo class with @Configuration to enjoy the power of programmatic configuration in favor of XML.
