如何使用Java解析XOP / MTOM SOAP响应？

Question

我只想知道，是否有任何简单的方法可以解析MTOM / XOP
SOAP响应。问题是我使用纯HTTP发送肥皂消息和javax.xml来解析响应。但是某些服务以mulipart /
related回应了我，它需要更复杂的逻辑来解析它（性能很重要）。因此，我想知道我是否可以以某种方式利用apache
cxf，apache公理或任何其他库来解析MTOM / XOP SOAP响应？

这些单元测试向您展示了如何使用CXF从MTOM消息中提取附件。我将内联其中一项测试，以防将来此链接不存在：

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=\"<[e-mail]>\"; "
                + "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');
}

您的情况ct将来自响应的内容类型标头。该"mimedata"会是响应的内容。
