如何更改 "SOAP-ENV" 默认前缀 Spring-WS

Question

我使用 Spring-WS 创建了一个网络服务。为了保持与旧系统的兼容性，我需要将命名空间前缀从 SOAP-ENV 更改为 soap.

我知道 SOAP-ENV 和 soap 只是名称空间前缀。只要它们引用正确的命名空间 ("http://schemas.xmlsoap.org/soap/envelope/")，就应该没问题。

但是旧系统将解析器代码硬编码为仅期望 soap 名称空间前缀。

当前回复：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
   ...
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

预期响应：

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

这是我到目前为止尝试过的方法

创建 EndpointInterceptorAdapter 子类。这将拦截 SOAP response/fault 并更改 SOAP 信封。这可行，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);
    }
  }
}

更改 package-info.java 包中包含生成的 WSDL 类。我已经使用我公司的名称空间前缀成功完成了此操作，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;

在Spring-WS中，有没有一种理想的方法可以将SOAP-ENV更改为soap？

顺便说一句，这是设置这个前缀的代码。 StroapElement.java

更好的解决方案

使用 SOAPMessage API 而不是 DOM。

  private void alterSoapEnvelope(SaajSoapMessage soapResponse) {
    try {
      SOAPMessage soapMessage = soapResponse.getSaajMessage();
      SOAPPart soapPart = soapMessage.getSOAPPart();
      SOAPEnvelope envelope = soapPart.getEnvelope();
      SOAPHeader header = soapMessage.getSOAPHeader();
      SOAPBody body = soapMessage.getSOAPBody();
      SOAPFault fault = body.getFault();
      envelope.removeNamespaceDeclaration(envelope.getPrefix());
      envelope.addNamespaceDeclaration(PREFERRED_PREFIX, SOAP_ENV_NAMESPACE);
      envelope.setPrefix(PREFERRED_PREFIX);
      header.setPrefix(PREFERRED_PREFIX);
      body.setPrefix(PREFERRED_PREFIX);
      if (fault != null) {
        fault.setPrefix(PREFERRED_PREFIX);
      }
    } catch (SOAPException e) {
      e.printStackTrace();
    }
  }

现在快多了。

我用SAAJ。试试这个。

soapEnvelope.removeNamespaceDeclaration("SOAP-ENV");
soapEnvelope.addNamespaceDeclaration("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
soapEnvelope.setPrefix("soapenv");
soapHeader.setPrefix("soapenv");
soapBody.setPrefix("soapenv");

别忘了： soapMessage.saveChanges();

补充点：

您必须使用 WsConfigurationAdapter 扩展 Web 服务配置 class，并在 Web 服务配置 class 中添加您的 CustomEndpointInterceptor，如下所述。

那么只有拦截器起作用了。
