Java JAXB和enum实现接口

我不熟悉JAXB（也不熟悉Stackoverflow！），在尝试封送和解封包含实现接口的枚举列表的对象时遇到了问题。 我看了一眼，尝试了一个类似的例子：

public class testXML {
    private static interface Animal {
        public String getName();
    }

    @XmlRootElement
    private static class Lion implements Animal {
        @XmlElement
        private String name;
        public Lion() { name = "Lion"; }
        @Override public String getName() {
            return name;
        }
    }

    @XmlRootElement
    private static class Dog implements Animal {
        @XmlElement
        private String name;
        public Dog() { name = "Dog"; }
        @Override public String getName() {
            return name;
        }
    }

    @XmlRootElement
    private static class Zoo {
      @XmlElementRefs({
          @XmlElementRef(name = "lion", type = Lion.class, required = true),
          @XmlElementRef(name = "dog", type = Dog.class, required = true)
      })
      public List<Animal> animals;
      public Zoo(Animal ... animals) {
          this.animals = Arrays.asList(animals);
      }
      public Zoo() {
          animals = null;
      }
      public Animal getAnimal(int i) {
          return animals.get(i);
      }
    }

    public static void main(String[] args) throws JAXBException {
        File file = new File("testXML.xml");
        JAXBContext context = JAXBContext.newInstance(
                Zoo.class,
                Lion.class,
                Dog.class);
        //SerializableParameter<ChannelParamEnum> result = new SerializableParameter(ChannelParamEnum.PARAM_CH_FGAIN, 1.0);
        Zoo result = new Zoo(new Lion(), new Dog());
        Marshaller marshaller = context.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
        marshaller.marshal(result, file);

        Zoo unmar = (Zoo)context.createUnmarshaller().unmarshal(file);
        Animal anim = unmar.getAnimal(0);
        System.out.println(anim);
    }
}

显然这不是我的用例，我必须使用枚举而不是类。我环顾了很多地方，但没有找到答案，所以非常感谢您的帮助

谢谢大家!

我终于找到了解决办法。这足以改变

  @XmlElementRefs({
      @XmlElementRef(name = "lion", type = Lion.class),
      @XmlElementRef(name = "dog", type = Dog.class)
  })

与

无论如何，我仍然觉得我在JAXB利用率方面遗漏了很多

我希望这有帮助

我面临着完全相同的问题。除了公认的答案外，您是否还尝试过其他解决方案？

Exception in thread "main" com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
Invalid @XmlElementRef : Type "package.testXML$Lion" or any of its subclasses are not known to this context.

  @XmlElementRefs({
      @XmlElementRef(name = "lion", type = Lion.class),
      @XmlElementRef(name = "dog", type = Dog.class)
  })

  @XmlElements({
      @XmlElement(name="lion", type=Lion.class),
      @XmlElement(name="dog", type=Dog.class)
  })
