Printing all properties set via Spring PropertyPlaceholderConfigurer

Question

I’d like to print the consolidated list of properties set in our application on startup. What is the best way to do this?

Thanks

This is my implementation:

public class CustomPropertySourcesPlaceholderConfigurer extends PropertySourcesPlaceholderConfigurer implements InitializingBean{

    public void afterPropertiesSet(){
        try{
            Properties loadedProperties = this.mergeProperties();
            for(Entry singleProperty : loadedProperties.entrySet()){
                logger.info("LoadedProperty: "+singleProperty.getKey()+"="+singleProperty.getValue());
            }
        }catch(Exception ex){
            ex.printStackTrace();
        }
    }
}
