MTOM支持ws：outbound-gateway

Question

我们有一个动态的ws-service客户端，如下所示：

    <si-ws:outbound-gateway id="wsOutboundGateway" uri="{uri}" reply-timeout="120000" fault-message-resolver="wsFaultMessageResolver">

        <si-ws:uri-variable name="uri" expression="headers.URL"/>

        <si-ws:request-handler-advice-chain>
            <ref bean="wsRetryAdvice"/>
        </si-ws:request-handler-advice-chain>

    </si-ws:outbound-gateway>

是否可以动态处理mtom附件，而无需自定义编组？ 或者例如它可以像这样，但如果答案有一个mtom，我们还有另一个处理案例？

    private static class DefaultSourceExtractor extends TransformerObjectSupport implements SourceExtractor<DOMSource> {

            @Override
            public DOMSource extractData(Source source) throws IOException, TransformerException {
                    if (source instanceof DOMSource) {
                            return (DOMSource)source;
                    }
                    DOMResult result = new DOMResult();
                    this.transform(source, result);
                    return new DOMSource(result.getNode());
            }
