JAXB 绑定从非抽象 XML 类型生成抽象 Java 类

使用JAXB绑定从非抽象XML类型生成抽象Java类

xjc person.xsd

java
public abstract class Person {
    public abstract String getName();
    public abstract void setName(String name);
    public abstract int getAge();
    public abstract void setAge(int age);
}

java
@XmlRootElement(name = "person")
public class PersonImpl extends Person {
    private String name;
    private int age;
    @XmlElement(name = "name")
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @XmlElement(name = "age")
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

java
public class Main {
    public static void main(String[] args) {
        try {
            JAXBContext jaxbContext = JAXBContext.newInstance(PersonImpl.class);
            Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
            Person person = (Person) jaxbUnmarshaller.unmarshal(new File("person.xml"));
            System.out.println("Name: " + person.getName());
            System.out.println("Age: " + person.getAge());
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
}
