Saaj-based client

Overview Saaj-soap with Attachments API for Java structure diagram is as follows: Body 1. There are four key parameters for how to obtain the key parameter of a SOAP request:

1. Xmlns-xml namespaces
   If you do not have a concept for namespaces, refer to: W3school-xml namespaces.
2. Address of the service
3. Service's name
4. Port's name

Get:

1. The targetnamespace of the root element of the WSDL document can be obtained to xmlns:
   
2. Additional three parameters can be obtained in the service element
   
   Yellow highlighted three places, respectively, can get the service Name,port name, the address of the service.
   It is worth saying that the name of the service here is the same as the name of the root element of the WSDL document, but it is only a coincidence; here is "really", there is just "look like".

2. Parameter declaration

/**address of the service*/Private Static FinalString ADDRESS = "Http://localhost:6666/service/interpret";/**Target Namespace*/Private Static FinalString target_name_space = "http://service.chapter1.jws.sand.ljl.cn/";/**the name of the service*/Private Static FinalString service_name = "Interpretserviceimplservice";/**Name of Port*/Private Static FinalString port_name = "Interpretserviceimplport";

3. Create a message

/*** Create and populate a SOAP message. *@return * @throwsSoapException*/PrivateSoapMessage CreateMessage ()throwsSoapException {//1. Create a messageSoapMessage message =messagefactory.newinstance (). CreateMessage (); //2. Get EnvelopeSoapEnvelope envelope =Message.getsoappart (). Getenvelope (); //3. Get the bodySoapbody BODY =Envelope.getbody (); //4. Constructing interpret elementsQName QName =NewQName (Target_name_space, "interpret", "NS"); //5. Adding elements to the bodySoapbodyelement bodyelement =body.addbodyelement (QName); //6. Adding child elementsBodyelement.addchildelement ("num"). SetValue ("112358")); returnmessage;}

The result of the above code creation:

<xmlns:soap-env= "http://schemas.xmlsoap.org/soap/envelope/">  <soap-env:header/><soap-env:body> 

About QName

New QName ("http://service.chapter1.jws.sand.ljl.cn/", "interpret", "ns");

The three parameters of the preceding code, respectively, represent the namespace, local name, and prefix. The equivalent of creating the following XML element:

<xmlns:ns= "http://service.chapter1.jws.sand.ljl.cn/"/>

About printing SoapMessage

The message can be printed to the specified output stream using Javax.xml.soap.SOAPMessage.writeTo (OutputStream out).
4. Send a message

/*** Sends a SOAP message and returns a SOAP message for the response. *@paramRequest *@return * @throwsmalformedurlexception*/PrivateSoapMessage Send (SoapMessage request)throwsmalformedurlexception {//1. Create a service based on address, ServiceNameURL url =NewURL (ADDRESS); QName ServiceName=NewQName (Target_name_space, service_name); Service Service=service.create (URL, serviceName); //2. Using service, create dispatch based on PortNameQName PortName =NewQName (Target_name_space, port_name); Dispatch<SOAPMessage> dispatch =Service.createdispatch (PortName, SoapMessage.class, Service.Mode.MESSAGE); //3. Sending the requestSoapMessage response =Dispatch.invoke (Request); returnresponse;}

The result of the response obtained by the above code:

<S:envelopexmlns:s= "http://schemas.xmlsoap.org/soap/envelope/">  <S:header/>  <S:body>     <Ns2:interpretresponseXmlns:ns2= "http://service.chapter1.jws.sand.ljl.cn/">       <Chnum>112358</Chnum>     </Ns2:interpretresponse>  </S:body></S:envelope>

5. Parsing results

Document doc = response.getsoappart (). Getenvelope ()       = Doc.getelementsbytagname ("Chnum"). Item (0)       . Gettextcontent ();
