Java CXF提供程序服务（jax ws）

我需要解析一个巨大的xml请求，因此我使用cxf提供程序，但是使用这个提供程序类，我必须返回与输入类对象相同的类对象

我的问题是，在处理输入StAXSource时，如何从提供程序返回带有修改的xml流的输出StAXSource

我的代码

@WebServiceProvider(
        portName = "MyService", serviceName = "service",
        targetNamespace = "mytarget.space.com",
        wsdlLocation = "WEB-INF/wsdl/my/wsd-file.wsdl")

public class MyServiceProvider implements Provider<StAXSource> {
    @Override
    public StAXSource invoke(StAXSource stAXSource) {
        XMLInputFactory xmlInputFactory = XMLInputFactory.newFactory();
        XMLOutputFactory xmlOutputFactory = XMLOutputFactory.newInstance();

        XMLEventReader xmlEventReader;
        XMLEventWriter xmlEventWriter;
        StAXSource outpuStaxSource = null;
        try {
            ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(16 * 1024);
            xmlEventReader = xmlInputFactory.createXMLEventReader(stAXSource.getXMLStreamReader());
            xmlEventWriter = xmlOutputFactory.createXMLEventWriter(byteArrayOutputStream);
            XMLStreamReader xmlStreamReader = xmlInputFactory.createXMLStreamReader(new InputStreamReader(new ByteArrayInputStream(byteArrayOutputStream.toByteArray())));
            outpuStaxSource = new StAXSource(xmlStreamReader);
            while (xmlEventReader.hasNext()){
               xmlEventWriter.add(xmlEventReader.nextEvent());
               xmlEventWriter.flush();
               xmlStreamReader.next();
            }

        } catch (Throwable er){

        }
        return outpuStaxSource;
    }
}

更新

因此，基本上我正在寻找一种直接将数据返回到流的方法，如本文（）所述，但我需要对CXF和JAX-WS执行相同的操作，而不是rest
