How to load properties file and pass it to java singleton (enum)

I have a unicast java class that has my application settings.

I used this approach: What is an efficient way to implement singleton pattern in Java?

So, I have a:

public enum MySettings {

   INSTANCE;

   // bunch of private vars


   private MySettings {
     // load a json file and set my properties
     JsonParser parser = jf.createJsonParser(new File("HARD_CODED_PATH_HERE"));
   }

   // public getters/setters here


}

So the problem is with the hardcoded path I have.

I created a settings.properties file in / WEB -INF / folder, now the problem is the only way to know how to load the properties file, it needs the servlet context:

Properties prop = new Properties();
propertiesload(getServletContext().....);

Is there any other way to download this?

So this properties file is a static view of the properties file? that is, is it very fast and efficient?

can you try putting your properties directly in the src folder instead of the WEB-INF folder?

Spring has the ability to render property files as beans. You can take this route, given that you have marked the "Spring" message.
