如何更改Spring-WS的“SOAP-ENV”默认前缀(How to change “SOAP-ENV” default prefix of Spring-WS)

 我使用Spring-WS创建了一个Web服务。 为了保持与旧系统的兼容性，我需要将名称空间前缀从SOAP-ENV更改为soap 。 
 
 我知道SOAP-ENV和soap只是命名空间前缀。 只要他们引用了正确的名称空间（ "http://schemas.xmlsoap.org/soap/envelope/" ），它应该没问题。 
 
 但旧系统对解析器代码进行了硬编码，只期望soap名称空间前缀。 
 
 当前的回应： 
 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
   ...
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
 
 预期回应： 
 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Header/>
   <soap:Body>
   ...
   </soap:Body>
</soap:Envelope>
 
 这是迄今为止我尝试过的 
 
 
 
 创建EndpointInterceptorAdapter子类。 这将拦截SOAP响应/错误并更改SOAP信封。 这有效，但在性能方面并不理想。 
public class CustomEndpointInterceptor extends EndpointInterceptorAdapter {

  private static final String DEFAULT_NS = "xmlns:SOAP-ENV";
  private static final String SOAP_ENV_NAMESPACE = "http://schemas.xmlsoap.org/soap/envelope/";
  private static final String PREFERRED_PREFIX = "soap";
  private static final String HEADER_LOCAL_NAME = "Header";
  private static final String BODY_LOCAL_NAME = "Body";
  private static final String FAULT_LOCAL_NAME = "Fault";

  @Override
  public boolean handleResponse(MessageContext messageContext, Object endpoint) throws Exception {
    SaajSoapMessage soapResponse = (SaajSoapMessage) messageContext.getResponse();
    alterSoapEnvelope(soapResponse);
    return super.handleResponse(messageContext, endpoint);
  }

  @Override
  public boolean handleFault(MessageContext messageContext, Object endpoint) throws Exception {
    SaajSoapMessage soapResponse = (SaajSoapMessage) messageContext.getResponse();
    alterSoapEnvelope(soapResponse);
    return super.handleFault(messageContext, endpoint);
  }

  private void alterSoapEnvelope(SaajSoapMessage soapResponse) {
    Document doc = soapResponse.getDocument();
    Element rootElement = doc.getDocumentElement();
    rootElement.setPrefix(PREFERRED_PREFIX);
    // Remove default SOAP namespace
    rootElement.removeAttribute(DEFAULT_NS);
    NodeList headerNodes = doc.getElementsByTagNameNS(SOAP_ENV_NAMESPACE, HEADER_LOCAL_NAME);
    NodeList bodyNodes = doc.getElementsByTagNameNS(SOAP_ENV_NAMESPACE, BODY_LOCAL_NAME);
    NodeList faultNodes = doc.getElementsByTagNameNS(SOAP_ENV_NAMESPACE, FAULT_LOCAL_NAME);
    // Remove Header node.
    if (headerNodes.getLength() != 0) {
      rootElement.removeChild(headerNodes.item(0));
    }
    // Change Body's SOAP namespace prefix.
    if (bodyNodes.getLength() != 0) {
      Element bodyElement = (Element) bodyNodes.item(0);
      bodyElement.setPrefix(PREFERRED_PREFIX);
    }
    if (faultNodes.getLength() != 0) {
      Element faultElement = (Element) faultNodes.item(0);
      faultElement.setPrefix(PREFERRED_PREFIX);
    }
  }
}
 
 
 在包含WSDL生成的类的包中更改package-info.java 。 我用我公司的名称空间前缀成功完成了这项工作，但它不适用于SOAP-ENV前缀。 
@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.com/ns/2008/02/02/webservices/blah",
xmlns = {
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://www.example.com/ns/2008/02/02/webservices/blah", prefix = ""),
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://schemas.example.com/ns/2007/10/blah", prefix = "ns2"),
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://example.com/ns/2007/23/05/blah/fundamental", prefix = "ns3"),
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://schemas.xmlsoap.org/soap/envelope/", prefix = "soap") // doesn't work
},
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.thomsonreuters.ts.ets.interdayws.soap.webservice;
 
 
 有没有一种理想的方法可以在Spring-WS中将SOAP-ENV更改为soap ？ 
 
 顺便说一句，这是设置这个前缀的代码。 StroapElement.java 

I've created a web service using Spring-WS. To maintain compatibility with the old system, I need to change namespace prefix from SOAP-ENV to soap.
 
I know that SOAP-ENV and soap are just namespace prefixes. As long as they refer to the correct namespace ("http://schemas.xmlsoap.org/soap/envelope/"), it should be fine.
 
But the old system hard coded the parser code to expect only soap namespace prefix.
 
Current response:
 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
   ...
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
 
Expected response:
 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Header/>
   <soap:Body>
   ...
   </soap:Body>
</soap:Envelope>
 
Here's what I've tried so far
 
 
 
Create EndpointInterceptorAdapter subclass. This will intercept SOAP response/fault and alter the SOAP envelope. This works, but it's not ideal in terms of performance.
 
public class CustomEndpointInterceptor extends EndpointInterceptorAdapter {

  private static final String DEFAULT_NS = "xmlns:SOAP-ENV";
  private static final String SOAP_ENV_NAMESPACE = "http://schemas.xmlsoap.org/soap/envelope/";
  private static final String PREFERRED_PREFIX = "soap";
  private static final String HEADER_LOCAL_NAME = "Header";
  private static final String BODY_LOCAL_NAME = "Body";
  private static final String FAULT_LOCAL_NAME = "Fault";

  @Override
  public boolean handleResponse(MessageContext messageContext, Object endpoint) throws Exception {
    SaajSoapMessage soapResponse = (SaajSoapMessage) messageContext.getResponse();
    alterSoapEnvelope(soapResponse);
    return super.handleResponse(messageContext, endpoint);
  }

  @Override
  public boolean handleFault(MessageContext messageContext, Object endpoint) throws Exception {
    SaajSoapMessage soapResponse = (SaajSoapMessage) messageContext.getResponse();
    alterSoapEnvelope(soapResponse);
    return super.handleFault(messageContext, endpoint);
  }

  private void alterSoapEnvelope(SaajSoapMessage soapResponse) {
    Document doc = soapResponse.getDocument();
    Element rootElement = doc.getDocumentElement();
    rootElement.setPrefix(PREFERRED_PREFIX);
    // Remove default SOAP namespace
    rootElement.removeAttribute(DEFAULT_NS);
    NodeList headerNodes = doc.getElementsByTagNameNS(SOAP_ENV_NAMESPACE, HEADER_LOCAL_NAME);
    NodeList bodyNodes = doc.getElementsByTagNameNS(SOAP_ENV_NAMESPACE, BODY_LOCAL_NAME);
    NodeList faultNodes = doc.getElementsByTagNameNS(SOAP_ENV_NAMESPACE, FAULT_LOCAL_NAME);
    // Remove Header node.
    if (headerNodes.getLength() != 0) {
      rootElement.removeChild(headerNodes.item(0));
    }
    // Change Body's SOAP namespace prefix.
    if (bodyNodes.getLength() != 0) {
      Element bodyElement = (Element) bodyNodes.item(0);
      bodyElement.setPrefix(PREFERRED_PREFIX);
    }
    if (faultNodes.getLength() != 0) {
      Element faultElement = (Element) faultNodes.item(0);
      faultElement.setPrefix(PREFERRED_PREFIX);
    }
  }
}
 
 
Change package-info.java in the package that contain WSDL generated classes. I've successfully done this with my company's namespace prefix, but it doesn't work for SOAP-ENV prefix.
 
@javax.xml.bind.annotation.XmlSchema(namespace = "http://www.example.com/ns/2008/02/02/webservices/blah",
xmlns = {
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://www.example.com/ns/2008/02/02/webservices/blah", prefix = ""),
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://schemas.example.com/ns/2007/10/blah", prefix = "ns2"),
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://example.com/ns/2007/23/05/blah/fundamental", prefix = "ns3"),
  @javax.xml.bind.annotation.XmlNs(namespaceURI = "http://schemas.xmlsoap.org/soap/envelope/", prefix = "soap") // doesn't work
},
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.thomsonreuters.ts.ets.interdayws.soap.webservice;
 
 
Is there an ideal way to change SOAP-ENV to soap in Spring-WS?
 
By the way, here's the code that set this prefix. StroapElement.java
