Use JAXWS to establish WebService clients and implement handler validation examples for SOAP messages _java

The previously used webservice were picked up as a result of the project, and Java native Jaxws, which did not require a jar package, was selected this time. First is the use of Wsimport, first share my usage: cmd, go to the project location first, and then run the following command

Copy Code code as follows:

Wsimport-keep-extension-s./src-p com.jaxws.test http://192.168.1.1:8080/service?wsdl

A variety of automatically generated client-related helper classes can be found under the Com.jaxws.test package. How to use these classes do not elaborate on the internet a lot of information. Then you write the calling class yourself (I'm just a method here and will be called on the line)

Copy Code code as follows:

Public String Jaxws (object[] opargs)
{
Servicesservice service=new Servicesservice ();

adding headers to Soap
Service.sethandlerresolver (New Handlerresolver () {
Public listlistAdd authentication information
Handlerlist.add (New ClientHandler ());
return handlerlist;
}
});

String result =service.getservicesport (). GetResults (Opargs.tostring ());
Get the results
SYSTEM.OUT.PRINTLN (result);
return result;
}

Note that "//Add authentication information Handlerlist.add (new ClientHandler ());", so we also need to create a new ClientHandler class to implement the authentication message assembly, as follows:

Copy Code code as follows:

Package com.jaxws.test;

Import Java.util.Set;
Import Javax.xml.namespace.QName;
Import javax.xml.soap.*;
Import Javax.xml.ws.handler.MessageContext;
Import Javax.xml.ws.handler.soap.SOAPHandler;
Import Javax.xml.ws.handler.soap.SOAPMessageContext;

public class ClientHandler implements soaphandler<soapmessagecontext> {

public boolean handlemessage (Soapmessagecontext ctx) {

Outbound, that is, before the client makes the request, add the header information
Boolean request_p= (Boolean) Ctx.get (Messagecontext.message_outbound_property);
if (request_p) {
try {
SoapMessage msg=ctx.getmessage ();
SoapEnvelope Env=msg.getsoappart (). Getenvelope ();
SoapHeader Hdr=env.getheader ();
if (hdr==null) Hdr=env.addheader ();

Add the authentication information header

QName (String NamespaceURI, String localpart, string prefix)
QName (String NamespaceURI, String localpart)
QName (String Localpart)
Namespace for @param namespaceuri:qname
@param the local part of Localpart:qname
Prefix for @param prefix:qname
QName name=new QName ("http://csdc.info/", "Authentication", "Wsse");
Soapheaderelement Header = hdr.addheaderelement (name);

Addchildelement (String localname, String prefix,string uri)
Addchildelement (string localname, string prefix)
Addchildelement (String localname)
@param uri: namespace name uri for new element
@param localname: The local name of the new element
@param prefix: space prefix for new element names
See the API for JDK 1.6
SoapElement userelement = header.addchildelement ("Username", "Wsse");
Userelement.addtextnode ("admin");
SoapElement passelement = header.addchildelement ("Password", "Wsse");
Passelement.addtextnode ("admin");

Msg.savechanges ();

Output SOAP messages to System.out, the console
Msg.writeto (System.out);

return true;
catch (Exception e) {
E.printstacktrace ();
}
}
return false;
}

@Override
public boolean Handlefault (Soapmessagecontext context) {
TODO auto-generated Method Stub
return false;
}

@Override
public void Close (Messagecontext context) {
TODO auto-generated Method Stub
}

@Override
Public set<qname> getheaders () {
TODO auto-generated Method Stub
return null;
}
}

This class adds a header message to all of the SOAP messages, and my header message here is as follows:

Copy Code code as follows:

<wsse:authentication xmlns:wsse= "http://csdc.info/" >
<wsse:Username>admin</wsse:Username>
<wsse:Password>admin</wsse:Password>
</wsse:Authentication>

This enables the JAXWS-based WebService client with SOAP header authentication.
