【问题描述】：
我正在使用带有自定义 WebServiceMessageCallback 的 spring-ws (2.1.4) WebServiceTemplate 插入带有 SAML 的安全标头，我将收到该 SAML 作为 org.w3c.dom.Element 并且仅创建自己用于测试。
我使用webServiceTemplate.marshalSendAndReceive(request, new HeaderCallback(ctx, uri)) 来编组并发送我的请求。
我的问题是服务器端的签名验证失败，摘要不匹配。比较发送前和接收后 SAML 的输出，我发现在接收方我有命名空间声明，这些元素在发送前没有命名空间声明。
我目前在回调中做了什么：
@Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
super.doWithMessage(message);
Assert.isInstanceOf(SoapMessage.class, message);
SoapMessage soapMessage = (SoapMessage) message;
SoapHeaderElement securityHeader = soapMessage.getSoapHeader().addHeaderElement(WS_SECURITY_NAME);
try {
Transformer t = TransformerFactory.newInstance().newTransformer();
t.transform(new DOMSource(assertion), securityHeader.getResult());
} catch (org.springframework.oxm.MarshallingException ex) {
throw new IOException(ex);
}
有谁知道如何将元素插入 SOAP XML 以确保元素不会被修改？或者是否有其他方法可以使用 Spring WebServiceTemplate 实现这一目标？
我遇到了org.apache.ws.security.saml.ext.SAMLCallback，它有一个方法setAssertionElement，但是我没有找到如何使用WebServiceTemplate（分别为Wss4jSecurityInterceptor）来实现它，特别是考虑到我需要传入现有的SAML断言作为参数。

编辑：我找到了一种不添加额外命名空间的方法。我现在正在做的是使用javax.xml.soap.SOAPMessage 并导入节点：
@Override
public void doWithMessage(WebServiceMessage message) throws IOException, TransformerException {
super.doWithMessage(message);
Assert.isInstanceOf(SaajSoapMessage.class, message);
try {
SOAPMessage soapMessage = ((SaajSoapMessage) message).getSaajMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPEnvelope soapEnvelope = soapPart.getEnvelope();
if (soapEnvelope.getHeader() == null) {
soapEnvelope.addHeader();
}
SOAPHeaderElement securityElement = soapEnvelope.getHeader().addHeaderElement(WS_SECURITY_NAME);
securityElement.appendChild(soapPart.importNode(assertion, true));
} catch (SOAPException ex) {
throw new IOException(ex);
}
}
但是，即使 diff 显示输出之间没有差异验证仍然失败。在这一点上，我不确定我是否可以信任输出，并且这样做确实不会改变 SAML...
还有什么可能导致摘要不匹配的想法吗？
【问题讨论】：
-
您能给我们看一下 XML 的前/后代码片段吗？
-
你使用什么样的消息工厂？ SAAJ 还是 Axiom？
-
我正在使用
SaajSoapMessageFactory。
