在Java中从SOAPMessage获取原始XML

import javax.xml.soap.SOAPMessage;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamResult;

// 获取原始XML字符串
public static String getOriginalXML(SOAPMessage soapMessage) {
    try {
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Source sourceContent = soapMessage.getSOAPPart().getContent();
        StringWriter stringWriter = new StringWriter();
        StreamResult result = new StreamResult(stringWriter);
        transformer.transform(sourceContent, result);
        return stringWriter.toString();
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}
