Java使用JAXBContext从XML中提取值

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import java.io.File;

public class JAXBExample {
    public static void main(String[] args) {
        try {
            // 创建JAXBContext对象
            JAXBContext jaxbContext = JAXBContext.newInstance(Person.class);

            // 创建Unmarshaller对象
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

            // 加载XML数据
            File xmlFile = new File("person.xml");

            // 反序列化XML数据
            Person person = (Person) unmarshaller.unmarshal(xmlFile);

            // 提取值
            System.out.println("Name: " + person.getName());
            System.out.println("Age: " + person.getAge());
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
}
