Creating a Spring enum bean and passing the value of a method call

Question

I have this Singleton:

   public enum Elvis {
       INSTANCE;
       private int age;

       public int getAge() {
           return age;
       }
   }
         


        

Answer 1

You can use Spring Expression Language:

<constructor-arg value = "#{elvis.age}" />

or without elvis bean:

<constructor-arg value = "#{T(com.xyz.Elvis).INSTANCE.age}" />
