Java HTML/XML - 如何使用JAXB与抽象方法覆盖

public abstract class MyAbstractClass {

  private String value;
  private String dataType;

  public String getValue() {
    return value;
  }
  public void setValue(String value) {
    this.value = value;
  }
  public String getDataType() {
    return dataType;
  }
  public void setDataType(String dataType) {
    this.dataType = dataType;
  }

  public abstract String getMatch();
  public abstract void setMatch(String match);
}

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="MyAbstractClass")
public class MyClass extends MyAbstractClass {

  private String match;

  @Override
  public String getMatch() {
    return match;
  }

  @Override
  public void setMatch(String match) {
    this.match = match; 
  }

}

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

public class Main {

  public static void main(String[] args) throws JAXBException {

      MyClass my = new MyClass();
      my.setDataType("data type");
      my.setMatch("STRING MATCH");
      my.setValue("value");

      JAXBContext context = JAXBContext.newInstance(MyClass.class);
      Marshaller m = context.createMarshaller();
      m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
      m.marshal(my, System.out);
  }

}
