How to dynamically update the argument of OOTB hibernate validator annotations?

Question

I use the @Min annotation for field validation.

@Min(100)
private Long cost;

I want to extract the argument of the annotation in a separate configuration file.

Is there way to achieve it?

P.S.

I understrand that I can write my own annotation and my own validator but I want to reuse a library's code.

No way to do it with annotations like @Min, @Max and so on. You can use @AssertTrue to annotate a method of your entity in which your own validation logic will be implemented.

public class MyEntity {
     private Long cost;

     //getters and setters...
     @AssertTrue
     public boolean isValid() {
          long minCost = MyExternalConfig.getMinCost(); //get data from where you want
          return cost > minCost; 
     }

}
