[英]How to change namespace prefix in SOAP webservice request created with SOAPMessage?
When I create my SOAP request using the javax.xml.soap.SOAPMessage
class, I get a namespace prefix in my XML like <SOAP-ENV:Envelope>
. When I create my SOAP request using the
javax.xml.soap.SOAPMessage
class, I get a namespace prefix in my XML like <SOAP-ENV:Envelope>
.
Is there a simple way to change the namespace prefix to <soapenv:Envelope>
?有没有一种简单的方法可以将命名空间前缀更改为
<soapenv:Envelope>
?
The XML namespace prefix should not matter as long as you are calling a well behaved web service.只要您调用行为良好的 web 服务,XML 命名空间前缀就无关紧要。 So
SOAP-ENV:
, soapenv:
, or whatever:
are basically the same thing as long as they both refer to the same namespace.因此
SOAP-ENV:
、 soapenv:
或whatever:
只要它们都引用相同的命名空间,它们基本上是相同的。
With that being said, if you really need to do this for some reason, here is some minimally working code.话虽如此,如果您出于某种原因确实需要这样做,这里有一些最低限度的工作代码。 I'm calling this service .
我打电话给这个服务。
package soap;
import java.io.IOException;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.MimeHeaders;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPBodyElement;
import javax.xml.soap.SOAPConnection;
import javax.xml.soap.SOAPConnectionFactory;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPException;
import javax.xml.soap.SOAPHeader;
import javax.xml.soap.SOAPMessage;
public class Client {
public static void main(String[] args) throws SOAPException, IOException {
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();
MimeHeaders mimeHeader = message.getMimeHeaders();
mimeHeader.setHeader("SOAPAction", "http://tempuri.org/Add");
SOAPBody body = message.getSOAPBody();
SOAPHeader header = message.getSOAPHeader();
QName bodyName = new QName("http://tempuri.org/", "Add", "tmp");
SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
SOAPElement intA = bodyElement.addChildElement(new QName("http://tempuri.org/", "intA", "tmp"));
intA.addTextNode("123");
SOAPElement intB = bodyElement.addChildElement(new QName("http://tempuri.org/", "intB", "tmp"));
intB.addTextNode("456");
message.writeTo(System.out);
System.out.println();
// -----------------> Now changing the prefix before making the call
SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
envelope.removeNamespaceDeclaration(envelope.getPrefix());
String prefix = "soapenv";
envelope.addNamespaceDeclaration(prefix, "http://schemas.xmlsoap.org/soap/envelope/");
envelope.setPrefix(prefix);
header.setPrefix(prefix);
body.setPrefix(prefix);
// <---------------- done changing the prefix
message.writeTo(System.out);
System.out.println();
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnectionFactory.createConnection();
URL endpoint = new URL("http://www.dneonline.com/calculator.asmx");
SOAPMessage response = connection.call(message, endpoint);
connection.close();
response.writeTo(System.out);
}
}
I've printed the request message before and after the transformation.我已经在转换前后打印了请求消息。 The output is as follows (formatting not included:D):
output如下(不包括格式:D):
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<tmp:Add xmlns:tmp="http://tempuri.org/">

<tmp:intB>456</tmp:intB>
</tmp:Add>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header/>
<soapenv:Body>
<tmp:Add xmlns:tmp="http://tempuri.org/">

</soapenv:Envelope>
