我应该怎么做才能让java输出XML？

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

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

            // 创建Marshaller
            Marshaller marshaller = jaxbContext.createMarshaller();
            marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

            // 创建Java对象
            YourClass obj = new YourClass();
            // 设置对象属性...

            // 转换为XML并输出到文件
            File xmlFile = new File("output.xml");
            marshaller.marshal(obj, xmlFile);

            System.out.println("Java对象已成功转换为XML！");
        } catch (JAXBException e) {
            e.printStackTrace();
        }
    }
}
