无法优化 SOAP 数据包，传输数据。我做错了什么？

使用 JBDS 生成的客户端类。我查看了很多示例，无法实现在包外传输文件的能力：

</ SOAP-ENV: Envelope>
---- boundary388.5294117647058824932.470588235294118--
Content-Id: <1.B1150656.EC8A.4B5A.8835.A932E318190B>
Content-Transfer-Encoding: binary
CONTENT-TYPE: application / octet-stream
..........

我改了参数，结果总是这样：

<ns2:AttachmentContentList>
                <ns2:AttachmentContent>
                    <ns2:Id>request.zip</ns2:Id>
                    <ns2:Content>UEsDBBQACAg......

【解决方案1】：

发现问题。如果添加了 handlerList，MTOM 将停止工作。请告诉我如何同时使用 handlerList 和 MTOM？

        List<Handler> handlerList = binding.getHandlerChain();
        // handlerList.add(new Handler1());
        // handlerList.add(new Handler2());
        handlerList.add(handler1);
        handlerList.add(handler2);
        binding.setHandlerChain(handlerList);
