这些单元测试向您展示如何使用CXF从MTOM消息中提取附件。如果以后这个链接不存在，我会内联其中一个测试：

These unit tests show you how to use CXF to extract attachments out of an MTOM message. I'll inline one of the tests in case this link doesn't exist in the future:

private MessageImpl msg;

@Before
public void setUp() throws Exception {
    msg = new MessageImpl();
    Exchange exchange = new ExchangeImpl();
    msg.setExchange(exchange);
}

@Test
public void testDeserializerMtom() throws Exception {
    InputStream is = getClass().getResourceAsStream("mimedata");
    String ct = "multipart/related; type=\"application/xop+xml\"; "
                + "start=\"<soap.xml@xfire.codehaus.org>\"; "
                + "start-info=\"text/xml; charset=utf-8\"; "
                + "boundary=\"----=_Part_4_701508.1145579811786\"";

    msg.put(Message.CONTENT_TYPE, ct);
    msg.setContent(InputStream.class, is);

    AttachmentDeserializer deserializer = new AttachmentDeserializer(msg);
    deserializer.initializeAttachments();

    InputStream attBody = msg.getContent(InputStream.class);
    assertTrue(attBody != is);
    assertTrue(attBody instanceof DelegatingInputStream);

    Collection<Attachment> atts = msg.getAttachments();
    assertNotNull(atts);

    Iterator<Attachment> itr = atts.iterator();
    assertTrue(itr.hasNext());

    Attachment a = itr.next();
    assertNotNull(a);

    InputStream attIs = a.getDataHandler().getInputStream();

    // check the cached output stream
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    IOUtils.copy(attBody, out);
    assertTrue(out.toString().startsWith("<env:Envelope"));

    // try streaming a character off the wire
    assertTrue(attIs.read() == '/');
    assertTrue(attIs.read() == '9');
}

在您的情况下， ct 将来自响应的内容类型标头。 mimedata将是回复的内容。

In your case, the ct will come from the content type header of the response. The "mimedata" will be the content of the response.
