JAXB 将多个 XML 元素解组为单个类

使用JAXB（Java Architecture for XML Binding）可以很方便地将多个XML元素解组为单个类。JAXB是Java语言中用于将XML和Java对象相互转换的一种技术。它使得开发人员能够以面向对象的方式处理XML数据。

java
@XmlRootElement
public class Person {
    private String name;
    private int age;
    // 省略构造函数、getter和setter方法
    @XmlElement
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @XmlElement
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}

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