Access all Environment properties as a Map or Properties object

You need something like this, maybe it can be improved. This is a first attempt:

...
import org.springframework.core.env.PropertySource;
import org.springframework.core.env.AbstractEnvironment;
import org.springframework.core.env.Environment;
import org.springframework.core.env.MapPropertySource;
...

@Configuration
...
@org.springframework.context.annotation.PropertySource("classpath:/config/default.properties")
...
public class GeneralApplicationConfiguration implements WebApplicationInitializer 
{
    @Autowired
    Environment env;

    public void someMethod() {
        ...
        Map<String, Object> map = new HashMap();
        for(Iterator it = ((AbstractEnvironment) env).getPropertySources().iterator(); it.hasNext(); ) {
            PropertySource propertySource = (PropertySource) it.next();
            if (propertySource instanceof MapPropertySource) {
                map.putAll(((MapPropertySource) propertySource).getSource());
            }
        }
        ...
    }
...

Basically, everything from the Environment that’s a MapPropertySource (and there are quite a lot of implementations) can be accessed as a Map of properties.
