With JPA 2.2, Spring 5.1( SPR-16305) and Hibernate 5.3.0 (HHH-12135) you no longer need to use the mutable static property hack and can use dependency injection just like you would on a regular spring managed bean (note that annotations are no longer necessary):

public class MyAttributeConverter implements AttributeConverter {

    private final MySpringBean bean;

    public MyAttributeConverter(MySpringBean bean) {
        this.bean = bean;
    }

    public Y convertToDatabaseColumn(X attribute) {
      ...
    }

    public X convertToEntityAttribute(Y dbData) {
      ...
    }
}
