如何使用JAXB Marshaller流式传输大型文件？

JAXBContext jaxbContext = JAXBContext.newInstance(YourClass.class);

XMLStreamReader xmlStreamReader = XMLInputFactory.newFactory().createXMLStreamReader(new FileInputStream("large-file.xml"));
XMLStreamWriter xmlStreamWriter = XMLOutputFactory.newFactory().createXMLStreamWriter(new FileOutputStream("output.xml"));

Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Marshaller marshaller = jaxbContext.createMarshaller();

unmarshaller.setListener(new Unmarshaller.Listener() {
    @Override
    public void afterUnmarshal(Object target, Object parent) {
        // 处理解析后的对象
    }
});

marshaller.setListener(new Marshaller.Listener() {
    @Override
    public void beforeMarshal(Object source) {
        // 在序列化之前进行处理
    }
});

JAXBElement<YourClass> jaxbElement = unmarshaller.unmarshal(xmlStreamReader, YourClass.class);
marshaller.marshal(jaxbElement, xmlStreamWriter);

xmlStreamReader.close();
xmlStreamWriter.close();
