Java calls WebService Methods (2) - JAX-WS call WebService

The need to introduce other frameworks with JAX-WS (Java API for XML Web Services) call WebService, all comes with the JDK.

2.1, Dispatch way

Dispatch Payload way there and Message in two ways.

2.1.1, Payload way

In the payload, the only body part of the incoming SOAP message.

/**
 * dispatch Payload方式调用WebService
 * @param portName 端口名称
 * @param param 参数
 */
public static void dispatchPayload(String portName, String param) {
    try {
        StringBuffer source = new StringBuffer();
        source.append("<web:toTraditionalChinese xmlns:web=\"" + targetNamespace + "\">");
        source.append("<web:sText>").append(param).append("</web:sText>");
        source.append("</web:toTraditionalChinese>");
        StreamSource xmlSource = new new StreamSource ( new new StringReader (source.toString ())); 
        
        the URL of wsdlURL = new new the URL of (url); 
        QName serviceQName = new new QName (targetNamespace, "TraditionalSimplifiedWebService" ); 
        Service Service = Service.create (wsdlURL, serviceQName); 
        QName portQName = new new QName (targetNamespace, portName); 
        dispatch <Source> dispatch = service.createDispatch (. portQName, Source class , Service.Mode.PAYLOAD); 
        
        // the .NET server-side Soap1.1 needed, without error will be reported: server failed to recognize the value of HTTP header SOAPAction
        Map<String, Object> requestContext = dispatch.getRequestContext();
        requestContext.put(BindingProvider.SOAPACTION_USE_PROPERTY, Boolean.TRUE);
        requestContext.put(BindingProvider.SOAPACTION_URI_PROPERTY, "http://webxml.com.cn/toTraditionalChinese");
        
        Source orderSource = dispatch.invoke(xmlSource);
        StreamResult result = new StreamResult(new ByteArrayOutputStream());
        Transformer trans = TransformerFactory.newInstance().newTransformer();
        trans.transform(orderSource, result);
        ByteArrayOutputStream baos = (ByteArrayOutputStream) result.getOutputStream();
        String responseContent = new String(baos.toByteArray());
        System.out.println(responseContent);

        Reader file = new StringReader(responseContent);
        SAXReader reader = new SAXReader();
        Document dc = reader.read(file);
        Element root = dc.getRootElement();
        String r = root.elementText("toTraditionalChineseResult").trim();
        System.out.println(r);

    } catch (Exception e) {
        e.printStackTrace (); 
    } 
}

2.1.2, Message mode

In Message mode, we have the whole Soap incoming messages.

/ **

 * @param soapNamespace the SOAP message namespace entire message body, Soap1.1 and Soap1.2 not the same 
 * @param portName port name

public  static  void DispatchMessage (String soapNamespace, the portName String, String param) {
     the try { 
        the StringBuffer Source = new new the StringBuffer (); 
        source.append ( "<soapenv: Envelope xmlns: soapenv = \" "+ soapNamespace +" \ "xmlns: Web = \" "+ the targetNamespace + "\"> " ); 
        source.append ( " <soapenv: Header /> " );
        source.append("<soapenv:Body>");
        source.append("<web:toTraditionalChinese>");
        source.append("<web:sText>").append(param).append("</web:sText>");
        source.append("</web:toTraditionalChinese>");
        source.append("</soapenv:Body>");
        source.append("</soapenv:Envelope>");
        StreamSource xmlSource = new StreamSource(new StringReader(source.toString()));
        
        URL wsdlURL = new URL(url);
        QName serviceQName = new QName(targetNamespace, "TraditionalSimplifiedWebService");
        Service service = Service.create(wsdlURL, serviceQName);
        QName portQName = new QName(targetNamespace, portName);
        Dispatch<Source> dispatch = service.createDispatch(portQName, Source.class, Service.Mode.MESSAGE);
        
        //.NET的服务端Soap1.1需要，不加会报错误：服务器未能识别 HTTP 头 SOAPAction 的值
        Map<String, Object> requestContext = dispatch.getRequestContext();
        requestContext.put(BindingProvider.SOAPACTION_USE_PROPERTY, Boolean.TRUE);
        requestContext.put(BindingProvider.SOAPACTION_URI_PROPERTY, "http://webxml.com.cn/toTraditionalChinese");
        
        Source orderSource = dispatch.invoke(xmlSource);
        StreamResult result = new StreamResult(new ByteArrayOutputStream());
        Transformer trans = TransformerFactory.newInstance().newTransformer();
        trans.transform(orderSource, result);
        ByteArrayOutputStream baos = (ByteArrayOutputStream) result.getOutputStream();
        String responseContent = new String(baos.toByteArray());
        System.out.println(responseContent);

        Reader file = new StringReader(responseContent);
        SAXReader reader = new SAXReader();
        Document dc = reader.read(file);
        //节点名称为toTraditionalChineseResult 命名空间为http://webxml.com.cn/
        String r = dc.selectSingleNode("//*[local-name()='toTraditionalChineseResult' and namespace-uri()='http://webxml.com.cn/']").getText().trim();
        System.out.println(r);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

2.2, RPC way

RPC approach has not been recommended for use, service and client needs are JAVA, where the call is ready to work in the configuration of the local service; Xu ITestService the interface files are copied to the client works inside.
