如何在Java中将字符串转换为SOAPMessage？

我想知道有没有办法将字符串转换为 SOAPMessage ？

我说我有一个字符串如下：

String send = "<soap:Envelope xmlns:mrns0=\"http://sdp.SOMETHING.com/mapping/TSO\" xmlns:sdp=\"http://sdp.SOMETHING.com.tr/mapping/generated\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:xs=\"http://www.w3.org/2001/XMLSchema\">"
        + "<soap:Header>"
        + "<sdp:token>"
        + "<sdp:sessionId>" + sessionId + "</sdp:sessionId>"
        + "</sdp:token>"
        + "<sdp:transaction-list>"
        + "<sdp:transaction-id>" + 11 + "</sdp:transaction-id>"
        + "</sdp:transaction-list>"
        + "</soap:Header>"
        + "<soap:Body>"
        + "<sdp:SendSMSInput>"
        + "<sdp:EXPIRY_DATE>" + extime + "</sdp:EXPIRY_DATE>"
        + "<sdp:MESSAGE_CLASS>0</sdp:MESSAGE_CLASS>"
        + "<sdp:S_DATE>" + time + "</sdp:S_DATE>"
        + "<sdp:SHORT_NUMBER>1905</sdp:SHORT_NUMBER>"
        + "<sdp:SRC_MSISDN>" + numSend + "</sdp:SRC_MSISDN>"
        + "<sdp:TO_RECEIVERS>"
        + "<sdp:msisdn>" + numSend + "</sdp:msisdn>"
        + "</sdp:TO_RECEIVERS>"
        + "<sdp:MESSAGE_BODY>"
        + "<sdp:message>Message body here.</sdp:message>"
        + "</sdp:MESSAGE_BODY>"
        + "</sdp:SendSMSInput>"
        + "</soap:Body>"
        + "</soap:Envelope>";


当我这样做时：

    SOAPConnectionFactory sfc = SOAPConnectionFactory.newInstance();
    SOAPConnection connection = sfc.createConnection();
    InputStream is = new ByteArrayInputStream(send.getBytes());
    SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);
    request.removeAllAttachments();

    SOAPPart part = request.getSOAPPart();
    part.detachNode();
    SOAPEnvelope env = part.getEnvelope();
    env.detachNode();
    SOAPBody body = env.getBody();
    body.detachNode();
    SOAPHeader head = env.getHeader();
    head.detachNode();

    request.writeTo(System.out);

    URL endpoint = new URL("http://sdp.somewhere.com.tr/view/LbsOpaqueService.wsdl");
    SOAPMessage response = connection.call(request, endpoint);
    System.out.println(response.getContentDescription());

一切正常。但我仍然从服务器获得NULL。可能是什么原因？我改变了＆lt;和＆gt;逃避咒语。

将String转换为输入流，然后将其读入SOAP消息工厂。

InputStream is = new ByteArrayInputStream(send.getBytes());
SOAPMessage request = MessageFactory.newInstance().createMessage(null, is);

You can read about how to do this here.

这对我有用：

SOAPMessage sm = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(new MimeHeaders(), is);

答案 2 :(得分：1)

我测量到SOAPMessage与SAXSource的馈送速度比公认的答案中使用的内部SAAJ解析实现快约50％：

SOAPMessage message = messageFactory.createMessage();
message.getSOAPPart().setContent(new SAXSource(new InputSource(new StringReader(send))));

这是测试各种XML解析源和工厂缓存影响的基准测试：

答案 3 :(得分：0)

而不是：

System.out.println(response.getContentDescription());

获得回复后将其替换为以下行：

response.writeTo(System.out);

答案 4 :(得分：0)

这样你就可以从文件中读取：

byte[] encoded = Files.readAllBytes(Paths.get("C:/resources/soap/RequestFileReply.xml"));
InputStream bStream = new ByteArrayInputStream(encoded);
SOAPMessage request = MessageFactory.newInstance().createMessage(null, bStream);
SOAPBody body = request.getSOAPBody();

带注释的SOAP-XML字符串


    @protocol DetailsTableViewCellDelegate <NSObject>
    
    - (void) customCell:(DetailsTableViewCell *)cell yesBtnPressed:(bool)yes;
    
    @property (nonatomic, retain) NSString * yesChecked;

将SOAP-XML字符串转换为SOAP-Message对象

static boolean OMIT_XML_DECLARATION = true;
static String soapXML = "<env:Envelope xmlns:env=\"http://www.w3.org/2003/05/soap-envelope\">"
            + "<env:Body> "
            + "<product version=\"11.1.2.4.0\">  <!-- Data XML -->"
            + "<name>API Gateway</name> <company>Oracle</company> <description>SOA Security and Management</description>"
            + "</product> </env:Body> </env:Envelope>";

将SOAP消息对象转换为SOPA-XML字符串

public SOAPMessage getSoapMessage(String xmlData, boolean isToIgnoringComments) throws Exception {
    if (isToIgnoringComments) {
        Document doc = getDocument(xmlData); // SOAP MSG removing comment elements
        xmlData = toStringDocument(doc);
    }
    
    ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(xmlData.getBytes());
    MimeHeaders mimeHeaders = new MimeHeaders();
    SOAPMessage message = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(mimeHeaders, byteArrayInputStream);
    return message;
}
public static Document getDocument(String xmlData) throws Exception {
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    dbFactory.setNamespaceAware(true);
    dbFactory.setIgnoringComments(true);
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        InputSource ips = new org.xml.sax.InputSource(new StringReader(xmlData));
        Document doc = dBuilder.parse(ips);
    return doc;
}

完整示例：

public static String toStringDocument(Document doc) throws TransformerException {
    StringWriter sw = new StringWriter();
    TransformerFactory tf = TransformerFactory.newInstance();
    Transformer transformer = tf.newTransformer();
    if (OMIT_XML_DECLARATION) {
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    } else {
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
    }
    transformer.setOutputProperty(OutputKeys.METHOD, "xml");
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");

    transformer.transform(new DOMSource(doc), new StreamResult(sw));
    return sw.toString(); // sw.getBuffer().toString();
}
