我能够生成 SOAP 消息，但我不知道

  • 只为soapMessage标签添加前缀（不应该有命名空间）

     SOAPConnectionFactory soapConnectionFactory =
                SOAPConnectionFactory.newInstance();
 SOAPConnection connection =
                soapConnectionFactory.createConnection();
 SOAPFactory soapFactory =
                SOAPFactory.newInstance();

 MessageFactory factory =
                MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);

 SOAPMessage message = factory.createMessage();
 SOAPHeader header = message.getSOAPHeader();
 SOAPPart soapPart = message.getSOAPPart();
 SOAPEnvelope soapEnvelope = soapPart.getEnvelope();                
 SOAPBody body = soapEnvelope.getBody();

 soapEnvelope.removeNamespaceDeclaration(soapEnvelope.getPrefix());
 soapEnvelope.setPrefix("soap");
 body.setPrefix("soap");

 header.removeNamespaceDeclaration(header.getPrefix());
 header.setPrefix("soap");

 soapEnvelope.addNamespaceDeclaration("v9", "URL TO SERVER");

 Name bodyName;
 bodyName = soapFactory.createName("SearchHotels");
 SOAPBodyElement getList = body.addBodyElement(bodyName);
 getList.setPrefix("v9");

 Name childName = soapFactory.createName("SoapMessage", "v9", "URL TO SERVER");
 SOAPElement HotelListRequest = getList.addChildElement(childName);

 HotelListRequest.addChildElement("Hotel", "v9").addTextNode("Hilton");

我的 SOAP 消息

   ...
     <v9:SoapMessage xmlns:els="URL TO SERVER">
         ...

我的期望

   ...
      <v9:SoapMessage>
           ...

更新 ：

如果我使用以下内容，则会遇到以下错误

    SOAPElement HotelListRequest = getList.addChildElement("v9:SoapMessage");

    org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a 
                                             way which is incorrect with regard to namespaces.

要将命名空间前缀添加到所有标签，您必须在每个插入的子元素上重新声明所需的前缀（最终是命名空间），否则它将（隐式）从父元素继承命名空间。

例如尝试：

SOAPBodyElement getList = body.addBodyElement(bodyName, "v9", "http://URL TO SERVER");

或者

soapBody.addChildElement("SomeElement", "v9", "http://URL TO SERVER");

或者

soapBody.addChildElement("v9:SomeElement");

有时您可能必须使用QName对象而不仅仅是 aString或 a Name。

这在很大程度上取决于您使用的 SOAP-API/实现，但原则在任何地方都是相同的：重新声明（显式）或继承（隐式）。

在您预期的 SOAP 消息中，前缀的情况有所不同，似乎您正在编写客户端，请求在 .net 中开发的服务提供商，这就是您可能需要更改前缀的原因。

我认为您可以从以下代码中获取概念：

       MessageFactory messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL); 
    SOAPMessage soapMessage = messageFactory.createMessage(); 

    SOAPPart soapPart = soapMessage.getSOAPPart(); 

    SOAPEnvelope soapEnvelope = soapPart.getEnvelope(); 

    SOAPBody soapBody = soapEnvelope.getBody(); 

    soapEnvelope.removeNamespaceDeclaration(soapEnvelope.getPrefix()); 
    soapEnvelope.addNamespaceDeclaration("soap", "http://schemas.xmlsoap.org/soap/envelope/"); 

    soapEnvelope.setPrefix("soap"); 
    soapBody.setPrefix("soap"); 

    soapEnvelope.addNamespaceDeclaration("xsi", "http://www.w3.org/2001/XMLSchema-instance"); 
    soapEnvelope.addNamespaceDeclaration("xsd", "http://www.w3.org/2001/XMLSchema");   soapMessage.getSOAPHeader().detachNode(); 

    soapMessage.getMimeHeaders().setHeader("SOAPAction", "http://www.example.com/TransactionProcess");
