Access to external service services based on Wsdl2java

I. Introduction of Wsdl2java

Wsdl2java is a tool that CXF provides for generating client-side code that is similar in function to Wsimport. However, the Wsdl2java tool can only generate code that accesses services based on CXF Publishing. Wsdl2java is located in the Cxf_home/bin directory, so you need to add a directory to path when using this tool. The parameters of the Wsdl2java tool differ from the Wsimport, mainly:

-d parameter, specifying the directory in which the code is generated

-p parameter, specifying the new package structure that is generated

(Wsdlurl) The WSDL address of the –http://server.port/service?wsdl,webservice, the required parameter

Second, new Java project, and release WebService

Create a new Java project, named Hellocxf, to import the CXF related jar packages.

Create a new Com.hellocxf.service package in the SRC directory and create a new people class with the People class Code:

Package com.hellocxf.service; Import Javax.jws.webmethod;import Javax.jws.WebService; @WebServicepublic interface People {         publicstring SayHello (String name);         @WebMethod (exclude=true)         publicstring makefriend (String name);}

Create a new Com.hellocxf.serviceImpl package in the SRC directory and create a new student class with the student code:

Package Com.hellocxf.serviceImpl; Import Javax.jws.webmethod;import Javax.jws.WebService; Import Com.hellocxf.service.People; @WebServicepublic class Student implements people {          @Override         publicstring SayHello (String name) {                   //todo auto-generated method Stub                   System.out.println ("Hello:" +name);                   returnname;         }          @WebMethod (exclude=true)         @Override         publicstring makefriend (String name) {                   //todo auto-generated method Stub                   System.out.println ("Makefriend with" +name+ "student");                   Returnname;         } }

New Com.hellocxf.servicePublice package is created in the SRC directory and the Servicepublish class for publishing Webservice.servicepublish code is:

Package com.hellocxf.servicePublish; Import Javax.xml.ws.Endpoint; Import Com.hellocxf.service.people;import com.hellocxf.serviceImpl.Student; public class Servicepublish {          publicstatic void Main (string[] args) {                   //todo auto-generated method Stub                   Peoplemservice = new Student ();                                     stringaddress = "Http://localhost:8080/People";                   Endpoint.publish (Address,mservice);         } }

Run the Servicepublish class and publish the WebService service.

Iii. using the Wsdl2java tool to generate the client invoke service code

Create a new folder on the D drive Generatedcode

Open the cmd command and switch to the directory

Run Wsdl2java–d. HTTP://LOCALHOST:8080/PEOPLE?WSDL, generate code to access the service under the Generatedcode folder.

Iv. Create a new client project and invoke the WebService service

Create a new Java project in eclipse named Cxfclient

Copy the third generated. Java class file to the SRC directory as a whole.

Create a new Com.webservice.use package in the SRC directory and create a new class Serviceuse in the package. To complete the call to WebService, the code is:

Package com.webservice.use; Import Com.hellocxf.serviceimpl.people;import Com.hellocxf.serviceimpl.StudentService; public class Serviceuse {          publicstatic void Main (string[] args) {                   //todo auto-generated method stub                                     //< Wsdl:servicename= "Studentservice" >                   studentservicestudentservice = new Studentservice ();                                     <wsdl:portbinding= "tns:studentservicesoapbinding" name= "Studentport" >                   //<wsdl:bindingname= " Studentservicesoapbinding "type=" Ns1:people ">                   peoplepeople = Studentservice.getstudentport ();                                     Stringserviceresult = People.sayhello ("Yinyuchun");                   System.out.println (Serviceresult);                           

The service type that is created in the class Serviceuse code and the port and method of the call are obtained from the WSDL.
