The WebService of Java EE

1.WebService

A. Definition: WebService is a remote call technology across programming languages and cross-operating system platforms

B. Three major technologies: XML+XSD,SOAP,WSDL

C.SOAP Protocol = HTTP protocol + XML data format

D.WSDL: XML-based description language (equivalent to dictionaries, menus)

2. Service side:

A. Configuring in XML

    <Listener>        <Listener-class>Org.springframework.web.context.ContextLoaderListener</Listener-class>    </Listener> <!--Configuring the core servlet of the CXF framework -    <servlet>        <Servlet-name>Cxfservlet</Servlet-name>        <Servlet-class>Org.apache.cxf.transport.servlet.CXFServlet</Servlet-class>        <Load-on-startup>2</Load-on-startup>    </servlet>    <servlet-mapping>        <Servlet-name>Cxfservlet</Servlet-name>        <Url-pattern>/server/*</Url-pattern>    </servlet-mapping>

B. Building Spring-webservice.xml

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xmlns:jaxws= "Http://cxf.apache.org/jaxws"xsi:schemalocation= "Http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/ Beans Http://www.springframework.org/schema/beans/spring-beans.xsd "Default-lazy-init= "true">     <BeanID= "Webserviceserver"class= "Com.wode.server.impl.MyWebServiceImpl" />     <Jaxws:endpointID= "MyService"implementor= "#webserviceServer"Address= "/helloservice">    </Jaxws:endpoint> </Beans>

C. Building interfaces

@WebService  Public Interface MyWebService {    int int int  b);         int int int b);    }

D. Building implementation Class

@WebService (endpointinterface = "Com.wode.server.MyWebService") Public classMywebserviceimplImplementsMyWebService {@Override Public intAddintAintb) {//TODO auto-generated Method StubSystem.out.println (A +b); returnA +b; } @Override Public intMinus (intAintb) {//TODO auto-generated Method StubSystem.out.println (A-b); returnA-b; }}

E. Testing (need to run Tomcat server Tomcat:run first)

        New Jaxwsproxyfactorybean ();        Factorybean.setserviceclass (MyWebService. class );        Factorybean.setaddress ("Http://127.0.0.1:8080/myService/server/HelloService");        MyWebService Service=(MyWebService) factorybean.create ();        System.out.println (Service.add (1, 3));

F. Access http://127.0.0.1:8080/myService/server/HelloService?wsdl confirm that it is normal

G. Download apache-cxf-3.1.11 and configure environment variables

H. In console input

Wsdl2java-encoding Utf-8-D E:\EclipseWorkspace\myService http://127.0.0.1:8080/myService/server/HelloService?wsdl

I. Copy the project under the COM folder into the client project

3. Client

A. Use

        Mywebserviceimplservice service=New  mywebserviceimplservice ();        MyWebService MyWebService=service.getmywebserviceimplport ();        System.out.println (Mywebservice.add (Ten) + "client");
