Spring initializing the @Value annotation property from a static field

Having the following code:

public class Constants {
    public static final String X = "-";
}

And in another class

@Value("${some.property:Constants.X")
private String separator;

How can I achieve this? Constant property is not being loaded

Solution

  • You need to use the T operator with the actual package name where your Constants class is located like below

    @Value("#{T(your.package.Constants).X}")
private String separator;
