如何更改 Spring-WS 的“SOAP-ENV”默认前缀更好的解决方案

2022-09-03 00:30:10

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,我需要将命名空间前缀从 更改为 。SOAP-ENVsoap

我知道这一点,只是命名空间前缀。只要它们引用正确的命名空间(),就应该没问题。SOAP-ENVsoap"http://schemas.xmlsoap.org/soap/envelope/"

但是旧系统将解析器代码硬编码为仅期望命名空间前缀。soap

当前响应:

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

预期响应:

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

以下是我到目前为止尝试过的方法

  1. 创建子类。这将截获 SOAP 响应/故障并更改 SOAP 包络。这有效,但就性能而言并不理想。EndpointInterceptorAdapter

    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);
        }
      }
    }
    
  2. 包含 WSDL 生成的类的包中的更改。我已经成功地使用公司的命名空间前缀完成了此操作,但它不适用于前缀。package-info.javaSOAP-ENV

    @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式可以改变到Spring-WS?SOAP-ENVsoap

顺便说一句,下面是设置此前缀的代码。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();
    }
  }

现在快得多。

我使用SAAJ。试试这个。

  1. soapEnvelope.removeNamespaceDeclaration(“SOAP-ENV”);
  2. soapEnvelope.addNamespaceDeclaration(“soapenv”, “http://schemas.xmlsoap.org/soap/envelope/");
  3. soapEnvelope.setPrefix(“soapenv”);
  4. soapHeader.setPrefix(“soapenv”);
  5. soapBody.setPrefix(“soapenv”);

不要忘记: soapMessage.saveChanges();
