[英]Apache cxf attachment security
我尝试让我的apache cxf客户端签名和加密附件。 由于我现在有了解决方案,它确实对邮件正文进行了签名和加密,但是它忽略了附件。
我有以下代码:
Map<String, Object> props = new HashMap<>();
props.put("action", "Signature Encrypt");
props.put("signaturePropFile", "client.properties");
props.put("passwordCallbackClass", "******.KeystorePasswordCallback");
props.put("user", "node1");
props.put("signatureKeyIdentifier", "DirectReference");
props.put("signatureParts",
"{Element}{http://www.w3.org/2003/05/soap-envelope}Body;" +
"{}cid:Attachments;");
props.put("encryptionParts",
"{Content}{http://www.w3.org/2003/05/soap-envelope}Body;" +
"{Element}cid:Attachments;" );
props.put("encryptionPropFile", "client.properties");
props.put("encryptionKeyIdentifier", "IssuerSerial");
props.put("encryptionKeyTransportAlgorithm",
"http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p");
WSS4JOutInterceptor wss4jOut = new WSS4JOutInterceptor(props);
client.getOutInterceptors().add(wss4jOut);
我正在按照此示例制作代码。
{}cid:Attachments

问题在于,Apache CXF出于某种原因在将附件添加到消息的拦截器之前运行符号/加密拦截器。
一个简单的解决方法是添加您自己的WSS4J出入拦截器(问题在两种方式-传入/传出消息)都可以在加密/解密/签名(检查)完成之前添加附件。 基本上,您可以打开添加附件的SAAJ拦截器,并将代码的一部分从handleMessage方法复制粘贴到拦截器。 对于外来的感知器:
@Override
public void handleMessage(SoapMessage mc) throws Fault {
super.handleMessage(mc);
SOAPMessage soapMessage = mc.getContent(SOAPMessage.class);
if (soapMessage != null) {
if (soapMessage.countAttachments() > 0) {
if (mc.getAttachments() == null) {
mc.setAttachments(new ArrayList<Attachment>(soapMessage
.countAttachments()));
}
Iterator<AttachmentPart> it = CastUtils.cast(soapMessage.getAttachments());
while (it.hasNext()) {
AttachmentPart part = it.next();
String id = AttachmentUtil.cleanContentId(part.getContentId());
AttachmentImpl att = new AttachmentImpl(id);
try {
att.setDataHandler(part.getDataHandler());
} catch (SOAPException e) {
throw new Fault(e);
}
Iterator<MimeHeader> it2 = CastUtils.cast(part.getAllMimeHeaders());
while (it2.hasNext()) {
MimeHeader header = it2.next();
att.setHeader(header.getName(), header.getValue());
}
mc.getAttachments().add(att);
it.remove();
}
}
}
}
对于拦截器:
@Override
public void handleMessage(SoapMessage msg) throws Fault {
super.handleMessage(msg);
SOAPMessage soapMessage = msg.getContent(SOAPMessage.class);
soapMessage.removeAllAttachments();
Collection<Attachment> atts = msg.getAttachments();
if (atts != null) {
for (Attachment a : atts) {
if (a.getDataHandler().getDataSource() instanceof AttachmentDataSource) {
try {
((AttachmentDataSource) a.getDataHandler().getDataSource()).cache(msg);
} catch (IOException e) {
throw new Fault(e);
}
}
AttachmentPart ap = soapMessage.createAttachmentPart(a.getDataHandler());
Iterator<String> i = a.getHeaderNames();
while (i != null && i.hasNext()) {
String h = i.next();
String val = a.getHeader(h);
ap.addMimeHeader(h, val);
}
if (StringUtils.isEmpty(ap.getContentId())) {
ap.setContentId(a.getId());
}
soapMessage.addAttachmentPart(ap);
}
}
msg.setAttachments(Collections.<Attachment>emptyList());
msg.setContent(SOAPMessage.class, soapMessage);
}
