Question

我正在使用jax-ws并实现一个soap处理程序来修补出站请求。我在肥皂元素和节点元素中淹没了2天。

这是我的代码：

public boolean handleMessage(SOAPMessageContext context) {

    boolean outbound = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
    try {
        if (outbound) {
            SOAPMessage msg = context.getMessage();

            SOAPPart sp = msg.getSOAPPart();
            SOAPEnvelope env = sp.getEnvelope();
            SOAPBody body = env.getBody();
            NodeList list = body.getElementsByTagName("template");
            if(list.getLength() > 0) {
                Element template = (Element) list.item(0);
                if (template != null) {
                    String newBodyText = StringEscapeUtils.unescapeHtml(template.getTextContent());

                    Element bodyElement= XmlUtils.getBodyElement(newBodyText);
                    SOAPElement requestElement = SOAPFactory.newInstance().createElement(bodyElement);
                    body.removeContents();
                    body.insertBefore(requestElement, null);//HERE IS THE EXCEPTION
                    msg.saveChanges();
                    System.out.println("AFTER PATCHING REQUEST :");
                    msg.writeTo(System.out);
                }
            }
        }
    } catch(Exception e) {
        e.printStackTrace();
    }
    return true;
}

方法XmlUtils.getBodyElement如下：

public static Element getBodyElement(String fromText) {
    Element result = null;
    String cleanSource = StringEscapeUtils.unescapeJava(fromText).replaceAll("\\r\\n", "");


    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    try {
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document allDocument = builder.parse(new ByteArrayInputStream(cleanSource.getBytes()));
        NodeList list = allDocument.getElementsByTagName("soapenv:Body");
        if(list.getLength() > 0) {
            Element body = (Element)list.item(0);
            result =  (Element)body.getFirstChild();
        }
    } catch(Exception e) {
        e.printStackTrace();
    }
    return result;
}

最后，当我尝试在主体中插入新创建的SOAPElement时，我得到以下异常：

org.w3c.dom.DOMException: WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it.

我的想法已经不多了。你知道我应该怎么做吗？

使用自定义xml替换出站soap请求正文
