如何在 SOAPEnvelope 中添加命名空间声明

Question

在我的肥皂应用程序中，我使用的是 apache cxf。

这是我的代码，它将向服务器提交数据。

import org.apache.cxf.Bus;
import org.apache.cxf.BusFactory;
import org.apache.cxf.bus.spring.SpringBusFactory;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.ws.security.wss4j.DefaultCryptoCoverageChecker;
import org.apache.cxf.ws.security.wss4j.WSS4JInInterceptor;
import org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor;

SpringBusFactory bf = new SpringBusFactory();
URL              busFile = Submission.class.getResource(WSSEC_XML);    
File             f = new File(busFile.getPath());

Bus              bus = bf.createBus(busFile.toString());
BusFactory.setDefaultBus(bus);
BusFactory.setThreadDefaultBus(bus);

DefaultCryptoCoverageChecker coverageChecker = new DefaultCryptoCoverageChecker();

coverageChecker.setSignBody(true);
coverageChecker.setSignTimestamp(true);
coverageChecker.setEncryptBody(true);
coverageChecker.setSignAddressingHeaders(true);

MyClaimservice  service = new MyClaimservice();
Myclaims        port = service.getMyClaimsSoap11();
BindingProvider provider = (BindingProvider) port;
provider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, ENDPOINT_ADDRESS);
provider.getRequestContext().put(BindingProvider.SOAPACTION_URI_PROPERTY, SOAP_ACTION);

Client client = ClientProxy.getClient(port);

client.getOutInterceptors().add(new LoggingOutInterceptor());
client.getInInterceptors().add(new LoggingInInterceptor());
client.getInInterceptors().add(new WSS4JInInterceptor(getInProps()));
client.getOutInterceptors().add(new WSS4JOutInterceptor(getOutProps()));
client.getInInterceptors().add(coverageChecker);

SubmissionResponse response = port.submission(request);

我的请求数据是这样形成的。

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    ....
    ....
    ....
</soap:Envelope>

我需要向<soap:Envelope> 添加额外的命名空间。我预期的数据应该是这样的，

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:prefix1="url1" xmlns:prefix2="url2" xmlns:prefix3:"url3">
    ....
    ....
    ....
</soap:Envelope>

我尝试使用 Map 和 XpathExpressions 将这些前缀和命名空间 URL 添加到 DefaultCryptoCoverageChecker。但似乎它没有对我的请求数据进行任何更改。

Map<String, String> prefixes = new HashMap<String, String>();

prefixes.put("prefix1", "url1");
prefixes.put("prefix2", "url2");
prefixes.put("prefix3", "url3");
prefixes.put("prefix4", "url4");
prefixes.put("prefix5", "url5");

List<XPathExpression> xpaths = Arrays.asList(
        new XPathExpression("//prefix1:Envelope", CoverageType.SIGNED),
        new XPathExpression("//prefix2:Envelope", CoverageType.SIGNED),
        new XPathExpression("//prefix3:Envelope", CoverageType.SIGNED),
        new XPathExpression("//prefix4:Envelope", CoverageType.SIGNED),
        new XPathExpression("//prefix5:Envelope", CoverageType.SIGNED));

DefaultCryptoCoverageChecker coverageChecker = new DefaultCryptoCoverageChecker();

coverageChecker.addPrefixes(prefixes);
coverageChecker.addXPaths(xpaths);

coverageChecker.setSignBody(true);
coverageChecker.setSignTimestamp(true);
coverageChecker.setEncryptBody(true);
coverageChecker.setSignAddressingHeaders(true);

任何帮助将不胜感激。

更新 2：

我已经尝试过 Apache cxf 的转换功能。

Map<String, String> outTransformMap = Collections.singletonMap("{http://schemas.xmlsoap.org/soap/envelope/}Envelope", "Envelope");
TransformOutInterceptor transformOutInterceptor = new TransformOutInterceptor();
transformOutInterceptor.setOutTransformElements(outTransformMap);
client.getOutInterceptors().add(transformOutInterceptor);

根据http://cxf.apache.org/docs/transformationfeature.html#TransformationFeature-JAX-WS，上述代码将从Envelope 节点中删除该特定命名空间。我还可以通过看到 xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/ 正在从 <soap:Envelope> 中删除来确认它

我尝试了 transformOutInterceptor.setOutTransformElements(outTransformMap); 的反向操作，将其替换为 transformOutInterceptor.setOutAppendElements(outTransformMap);，其中 outTransformMap 现在将包含 Collections.singletonMap("{url1 (which I need to add)}Envelope", "Envelope");。但它不会将其作为新的命名空间附加到Envelope。我在这里做错了什么.. 除了默认命名空间之外，向<soap:Envelope> 添加额外的命名空间真的很难吗？

Answer 1

在cxf论坛上挖掘后，我找到了答案。

Map<String, String> nsMap = new HashMap<>();

nsMap.put("prefix1", "url1");
nsMap.put("prefix2", "url2");
nsMap.put("prefix3", "url3");
nsMap.put("prefix4", "url4");
nsMap.put("prefix5", "http://www.w3.org/2001/04/xmlenc#");

Client client = ClientProxy.getClient(port);   
client.getRequestContext().put("soap.env.ns.map", nsMap);

如果有人知道如何为 <soap:Header> 做同样的事情，我将不胜感激

Answer 2

您可以像这样添加标题：

UserCredentials authHeader = new UserCredentials();
    authHeader.setUsername(username);
    authHeader.setPassword(password);
    ArrayList<Header> headers = new ArrayList<Header>(1);
    try {
        Header soapHeader = new Header(new QName(TQIntegrationV2.TQIntegrationV2Soap.getNamespaceURI(), "UserCredentials"), authHeader, new JAXBDataBinding(UserCredentials.class));
        headers.add(soapHeader);
    } catch (JAXBException ex) {
        LOGGER.error("Exception trying to serialize header: {}", ex);
    }
    client.getRequestContext().put(Header.HEADER_LIST, headers);

如果你不想，你可以离开 setUsername/setPassword。
