How to load properties on util class

Question

I defined my properties file location on XML, and register my custom util class as bean. (with factory-method is “getInstance”)

What I want is I want to load my properties value before my Custom util construction us called.

class AUtil
{
   private static AUtil instance;

   @Value("something")
   private m;

   private AUtil() {}

   public static AUtil() {
       if (instance == null) instance = new AUtil();

       return instance;
   }
}

I think you should use @PostConstruct as: when the constructor is called, the bean is not yet initialized - i.e. no dependencies are injected. In the @PostConstruct method the bean is fully initialized and you can use the dependencies.
