26.18. 附加支持
POJO 模式: 支持带有 Attachment 和 MTOM 的 SOAP (请参阅 Payload Mode for enable MTOM)。但是,没有测试带有 Attachment 的 SOAP。由于附件被放入 POJO 中,因此用户通常不需要自行处理附件。如果没有启用 MTOM,则附件会被传播到 Camel 消息的附件。因此,可以通过 Camel Message API 检索附件
DataHandler Message.getAttachment(String id)
DataHandler Message.getAttachment(String id)
有效负载模式: 组件支持 MTOM。附件可以通过上述 Camel 消息 API 检索。支持带有 Attachment (SwA)的 SOAP,并可以检索附件。SwA 是默认值(与将 CXF 端点属性"mtom-enabled"设置为 false 的相同)。
要启用 MTOM,将 CXF 端点属性 "mtom-enabled" 设置为 true。
@Bean
public CxfEndpoint routerEndpoint() {
CxfSpringEndpoint cxfEndpoint = new CxfSpringEndpoint();
cxfEndpoint.setServiceNameAsQName(SERVICE_QNAME);
cxfEndpoint.setEndpointNameAsQName(PORT_QNAME);
cxfEndpoint.setAddress("/" + getClass().getSimpleName()+ "/jaxws-mtom/hello");
cxfEndpoint.setWsdlURL("mtom.wsdl");
Map<String, Object> properties = new HashMap<String, Object>();
properties.put("dataFormat", "PAYLOAD");
properties.put("mtom-enabled", true);
cxfEndpoint.setProperties(properties);
return cxfEndpoint;
}
@Bean

CxfSpringEndpoint cxfEndpoint = new CxfSpringEndpoint();

您可以生成带有附件的 Camel 消息,以发送到 Payload 模式的 CXF 端点。
Exchange exchange = context.createProducerTemplate().send("direct:testEndpoint", new Processor() {

Assert.assertEquals(1, out.getBody().size());

您还可以使用在 Payload 模式中从 CXF 端点接收的 Camel 消息。CxfMtomConsumerPayloadModeTest 演示了如何工作:
public static class MyProcessor implements Processor {
@SuppressWarnings("unchecked")
public void process(Exchange exchange) throws Exception {
CxfPayload<SoapHeader> in = exchange.getIn().getBody(CxfPayload.class);
// verify request
Assert.assertEquals(1, in.getBody().size());
Map<String, String> ns = new HashMap<String, String>();
ns.put("ns", MtomTestHelper.SERVICE_TYPES_NS);
ns.put("xop", MtomTestHelper.XOP_NS);
XPathUtils xu = new XPathUtils(ns);
Element body = new XmlConverter().toDOMElement(in.getBody().get(0));
Element ele = (Element)xu.getValue("//ns:Detail/ns:photo/xop:Include", body,
XPathConstants.NODE);
String photoId = ele.getAttribute("href").substring(4); // skip "cid:"
Assert.assertEquals(MtomTestHelper.REQ_PHOTO_CID, photoId);
ele = (Element)xu.getValue("//ns:Detail/ns:image/xop:Include", body,
XPathConstants.NODE);
String imageId = ele.getAttribute("href").substring(4); // skip "cid:"
Assert.assertEquals(MtomTestHelper.REQ_IMAGE_CID, imageId);
DataHandler dr = exchange.getIn().getAttachment(photoId);
Assert.assertEquals("application/octet-stream", dr.getContentType());
MtomTestHelper.assertEquals(MtomTestHelper.REQ_PHOTO_DATA, IOUtils.readBytesFromStream(dr.getInputStream()));
dr = exchange.getIn().getAttachment(imageId);
Assert.assertEquals("image/jpeg", dr.getContentType());
MtomTestHelper.assertEquals(MtomTestHelper.requestJpeg, IOUtils.readBytesFromStream(dr.getInputStream()));
// create response
List<Source> elements = new ArrayList<Source>();
elements.add(new DOMSource(DOMUtils.readXml(new StringReader(MtomTestHelper.RESP_MESSAGE)).getDocumentElement()));
CxfPayload<SoapHeader> sbody = new CxfPayload<SoapHeader>(new ArrayList<SoapHeader>(),
elements, null);
exchange.getOut().setBody(sbody);
exchange.getOut().addAttachment(MtomTestHelper.RESP_PHOTO_CID,
new DataHandler(new ByteArrayDataSource(MtomTestHelper.RESP_PHOTO_DATA, "application/octet-stream")));
exchange.getOut().addAttachment(MtomTestHelper.RESP_IMAGE_CID,
new DataHandler(new ByteArrayDataSource(MtomTestHelper.responseJpeg, "image/jpeg")));
}
}
public static class MyProcessor implements Processor {
@SuppressWarnings("unchecked")
public void process(Exchange exchange) throws Exception {
CxfPayload<SoapHeader> in = exchange.getIn().getBody(CxfPayload.class);

MtomTestHelper.assertEquals(MtomTestHelper.REQ_PHOTO_DATA, IOUtils.readBytesFromStream(dr.getInputStream()));

exchange.getOut().setBody(sbody);
exchange.getOut().addAttachment(MtomTestHelper.RESP_PHOTO_CID,
new DataHandler(new ByteArrayDataSource(MtomTestHelper.RESP_PHOTO_DATA, "application/octet-stream")));
exchange.getOut().addAttachment(MtomTestHelper.RESP_IMAGE_CID,
new DataHandler(new ByteArrayDataSource(MtomTestHelper.responseJpeg, "image/jpeg")));
}
}
原始模式: 不支持附件,因为它根本不处理消息。
CXF_RAW 模式 :支持 MTOM,可以通过上述 Camel 消息 API 检索附件。请注意,当收到多部分(即 MTOM)消息时,默认 SOAPMessage 到 String converter 将提供正文上的完整多部分有效负载。如果您只需要 SOAP XML 作为字符串,您可以使用 message.getSOAPPart ()设置消息正文,Camel convert 可以为您执行其余工作。
