问题
I have created web service using Spring-WS. When I send a request to the web service, this is the response I get in soap-ui:
enter code here
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<ns2:SendResponse xmlns:ns2="http://mycompany.com/schema/">
<ns2:SendResult>
<ns2:Token>A00179-02</ns2:Token>
</ns2:SendResult>
</ns2:SendResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Is there any way to get rid of the "ns2" namespace prefix from the response? I tried a couple of options: 1) Manually updated package-info.java to set the prefix to "":
@XmlSchema(namespace = "http://mycompany.com/schema/",
xmlns = {
@XmlNs(namespaceURI = "http://mycompany.com/schema/", prefix = "")
},
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.example.foo.jaxb;
2) Set the prefix to "" in the QName object in the endpoint class:
return new JAXBElement<SendAndCommitResponse>(new QName("http://mycompany.com/schema/",
"SendResponse",""), SendResponse.class, response);
Both didn't work. How to get rid off the "ns2" namespace prefix?
回答1:
I eventually found a solution for this.
My problem was caused by JDK 6 not shipping a full version of rt.jar (http://www.oracle.com/technetwork/java/javase/compatibility-137541.html).
I added the following to my maven config
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.2.6</version>
</dependency>
And then added
@XmlSchema(namespace = "http://mycompany.com/schema/",
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.UNQUALIFIED).
In the package-info.java (like suggested by @acdcjunior above)

it was hard
first: create a class that intercepts soap request and responses:
package examples.webservices.handler;
import java.lang.reflect.Method;
import java.util.Collections;
import java.util.Set;
import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPMessage;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
public class CorrigirConteudoRequisicaoSOAP implements SOAPHandler<SOAPMessageContext> {
public Set<QName> getHeaders() {
return Collections.emptySet();
}
public boolean handleMessage(SOAPMessageContext messageContext) {
this.corrigirConteudoRequisicaoSOAP(messageContext);
return true;
}
private void corrigirConteudoRequisicaoSOAP(SOAPMessageContext messageContext){
SOAPMessage msg = messageContext.getMessage();
try {
NodeList childNodes = msg.getSOAPBody().getChildNodes();
for(int k = 0; k < childNodes.getLength(); k++){
Node item = childNodes.item(k);
String localName = item.getLocalName();
{
item.setPrefix("");
Method m = SOAPElement.class.getDeclaredMethod("setElementQName", QName.class);
//I was forced to use reflection because the method setElementQname is not //visible, neither the class that implements it
m.invoke(item, new QName("", item.getLocalName()));
msg.saveChanges();
}
}
} catch (Exception e) {
try {
msg.writeTo(System.out);
} catch (Exception e1) {
e1.printStackTrace();
}
System.out.println();
}
}
public boolean handleFault(SOAPMessageContext messageContext) {
return true;
}
public void close(MessageContext messageContext) {
}
public static void main(String[] args)throws Exception {
}
}
second: associate the service to soap handle
public class PortalFornecedor {
public Usuario getUsuario(){
XIF367Afae09A3344Fbf2E1De819D6EcbaService classeComNomeFeio = new XIF367Afae09A3344Fbf2E1De819D6EcbaService();
Usuario service = classeComNomeFeio.getHTTPPort();
BindingProvider bp = (BindingProvider)service;
Map<String, Object> requestContext = bp.getRequestContext();
requestContext.put(BindingProvider.USERNAME_PROPERTY, "user");
requestContext.put(BindingProvider.PASSWORD_PROPERTY, "pass");
this.handle(service);
return service;
}
public Object getDashboard(){
return "";
}
// here we associate the service to soap handle
private BindingProvider handle(Usuario service) {
BindingProvider bp = (BindingProvider)service;
@SuppressWarnings("rawtypes")
List<Handler> chain = new ArrayList<Handler>();
chain.add(new CorrigirConteudoRequisicaoSOAP());
bp.getBinding().setHandlerChain(chain);
return bp;
}
public static void main(String[] args) {
PortalFornecedor pf = new PortalFornecedor();
Usuario usuario = pf.getUsuario();
LoginExecutarIN in = new LoginExecutarIN();
generated.Usuario user = new generated.Usuario();
user.setLogin("onias");
user.setSenha("12345");
user.setCodigoUsuario(0);
in.setParametroEntrada(user);
try {
LoginExecutarOUT out = usuario.loginExecutar(in);
// SOAPMessageContext.getMessage();
System.out.println(out.getRegistroSelecionado().getNome());
} catch (Exception e) {
e.printStackTrace();
}
}
}

I tried a few of the approaches discussed here, but nothing worked...
Below Class from the link - https://zhuanlan.zhihu.com/p/35298171 fixed my issue
Added the below interceptor to remove the namespaces -
public class PayloadPrefixInterceptor extends TransformerHelper implements EndpointInterceptor {
public static final String NAMESPACE = ObjectFactory.class.getPackage().getAnnotation(XmlSchema.class).namespace();
public static final String XMLNS = "xmlns:";
@Override
public boolean handleRequest(MessageContext messageContext, Object endpoint) throws Exception {
return true;
}
@Override
public boolean handleResponse(MessageContext messageContext, Object endpoint) throws Exception {
WebServiceMessage response = messageContext.getResponse();
Source payloadSource = response.getPayloadSource();
DOMResult result = new DOMResult();
transform(payloadSource, result);
removePrefix(result.getNode());
transform(new DOMSource(result.getNode()), response.getPayloadResult());
return true;
}
private void removePrefix(Node node) {
if (node == null) {
return;
}
if (node.getNodeType() == Node.ELEMENT_NODE) {
removeNamespaceDeclaration(node);
}
if (node.getPrefix() != null) {
node.setPrefix(null);
}
NodeList childNodes = node.getChildNodes();
if (childNodes != null) {
IntStream.of(0, childNodes.getLength()).forEach(index -> removePrefix(childNodes.item(index)));
}
Node nextSibling = node.getNextSibling();
if (nextSibling != null) {
removePrefix(nextSibling);
}
}
private void removeNamespaceDeclaration(Node node) {
NamedNodeMap attributes = node.getAttributes();
IntStream.range(0, attributes.getLength()).forEach(index -> {
Node attribute = attributes.item(index);
if (StringUtils.startsWith(attribute.getNodeName(), XMLNS) &&
StringUtils.equals(attribute.getNodeValue(), NAMESPACE)) {
attributes.removeNamedItemNS(attribute.getNamespaceURI(), attribute.getLocalName());
}
});
}
@Override
public boolean handleFault(MessageContext messageContext, Object endpoint) throws Exception {
return true;
}
@Override
public void afterCompletion(MessageContext messageContext, Object endpoint, Exception ex) throws Exception {
}
}
Registered the interceptor using below -
@EnableWs
@Configuration
public class Config extends WsConfigurerAdapter {
@Override
public void addInterceptors(List<EndpointInterceptor> interceptors) {
interceptors.add(new PayloadPrefixInterceptor());
super.addInterceptors(interceptors);
}
}
