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