如何在处理 SOAP 消息期间转换 SAAJ 对象？
How to cast SAAJ object during handling SOAP message?
同事们，我有xml需要在发送给客户端之前进行处理和配置：
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns2:request xmlns:ns2="http://mayacomp/Generic/Ws">
<in xmlns="http://mayacomp/Generic/Ws">
<requestHeader>
<requestUid>1234567890</requestUid>
<ns2:requestTimestamp>2015-02-11T07:46:00.000</ns2:requestTimestamp>
</requestHeader>
<ns2:FullDataView>
<ns2:ApplicationData>
<ns2:ProductType>0</ns2:ProductType>
</ns2:ApplicationData>
<ns2:ProductDetails>
<ns2:ProductCode>605</ns2:ProductCode>
</ns2:ProductDetails>
<ns2:Applicant>
<ns2:Surname>Клавиатурова</ns2:Surname>
<ns2:Address>
<ns2:Type>1</ns2:Type>
</ns2:Address>
<ns2:Address>
<ns2:Type>2</ns2:Type>
</ns2:Address>
<ns2:Email>test@test.ru</ns2:Email>
</ns2:Applicant>
</ns2:FullDataView>
</in>
</ns2:request>
</soapenv:Body>
</soapenv:Envelope>
我使用下一个方法来配置 soap 消息：
public void doWithMessage(WebServiceMessage message) {
SaajSoapMessage saajSoapMessage = (SaajSoapMessage)message;
try {
SOAPMessage soapMessage = saajSoapMessage.getSaajMessage();
SOAPPart soapPart = soapMessage.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
log.info("SOAPEnvelope prefix " + envelope.getPrefix());
envelope.removeNamespaceDeclaration(envelope.getPrefix());
envelope.addNamespaceDeclaration("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
envelope.setPrefix("soapenv");
/*Remove header*/
SOAPHeader header = soapMessage.getSOAPHeader();
header.detachNode();
SOAPBody body = envelope.getBody();
log.info("SOAPBody prefix " + body.getPrefix());
body.removeNamespaceDeclaration(body.getPrefix()) ;
body.addNamespaceDeclaration("soapenv", "http://schemas.xmlsoap.org/soap/envelope/");
body.setPrefix("soapenv");
/*Prepare body elements*/
Iterator itBodyElements = body.getChildElements();
String elementName = null;
/*Log all elements from body*/
log.info("Body elements: ");
NodeList nodeList = body.getElementsByTagName("*") ;
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
log.info(node.getNodeName());
}
}
/*Config body elements*/
while (itBodyElements.hasNext())
{
Object o = itBodyElements.next();
SOAPBodyElement bodyElement = (SOAPBodyElement) o;
log.info("Elements from 'Body' element = " + bodyElement.getLocalName() );
Iterator it2 = bodyElement.getChildElements();
while (it2.hasNext())
{
Object requestElement = it2.next();
SOAPBodyElement bodyRequest = (SOAPBodyElement) requestElement;
log.info(" Elements from '"+ bodyElement.getLocalName() + "' element = " + bodyRequest.getLocalName());
bodyRequest.removeNamespaceDeclaration(bodyRequest.getPrefix());
bodyRequest.setPrefix("");
Iterator it3 = bodyRequest.getChildElements();
while (it3.hasNext())
{
Object bodyRequestElement = it3.next();
SOAPBodyElement requestElementName = (SOAPBodyElement) bodyRequestElement;
log.info(" Elements from 'In' name = " + requestElementName.getLocalName());
requestElementName.setPrefix("");
elementName = requestElementName.getLocalName();
Iterator it4 = requestElementName.getChildElements();
while (it4.hasNext())
{
Object o4 = it4.next();
SOAPBodyElement bodyElement4 = (SOAPBodyElement) o4;
log.info(" Element from '" + elementName + "' name = " + bodyElement4.getLocalName());
bodyElement4.setPrefix("");
Iterator it5 = bodyElement4.getChildElements();
while (it5.hasNext())
{
Object o5 = it5.next();
//What it tried?
// TextImpl child5 = (TextImpl) o5; //java.lang.ClassCastException: com.sun.xml.internal.messaging.saaj.soap.impl.ElementImpl cannot be cast to com.sun.xml.internal.messaging.saaj.soap.impl.TextImpl
// ElementImpl child5 = (ElementImpl) o5; //Result:java.lang.ClassCastException: com.sun.xml.internal.messaging.saaj.soap.impl.ElementImpl cannot be cast to com.sun.xml.internal.messaging.saaj.soap.impl.TextImpl
// SOAPElement child5 = (SOAPElement)o5; //java.lang.ClassCastException: com.sun.xml.internal.messaging.saaj.soap.impl.TextImpl cannot be cast to javax.xml.soap.SOAPElement
// SOAPBodyElement child5 = (SOAPBodyElement) o5; //java.lang.ClassCastException: com.sun.xml.internal.messaging.saaj.soap.impl.TextImpl cannot be cast to javax.xml.soap.SOAPBodyElement
log.info(o5.getClass().toString());
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
问题是我无法将对象 o5 (class com.sun.xml.internal.messaging.saaj.soap.impl.ElementImpl) 转换为代码中描述的任何类型。
如何正确投射对象 o5？
谢谢。
根据 Javadoc，getChildElements 方法具有以下行为：
Returns an Iterator over all the immediate child Nodes of this element. This includes javax.xml.soap.Text objects as well as SOAPElement objects.
因此，在尝试投射之前，您需要检查节点是 Text 还是 SOAPElement。
