Distributed Systems (3)---Web Service combat--CXF Practice

Article Two: CXF practice

CXF Architecture Development WebService steps:

1 , establish Web Project

2 , prepare all the Jar Package

3 , Web. XML in the configuration CXF the core Servlet,cxfservlet

Server-side:

< display-name>cxf_demo</display-name><context-param><param-name>contextconfiglocation</ Param-name><param-value>classpath:applicationcontext-server.xml</param-value></context-param ><listener><listener-class>org.springframework.web.context.contextloaderlistener</ listener-class></listener><servlet><servlet-name>cxfservlet</servlet-name>< servlet-class>org.apache.cxf.transport.servlet.cxfservlet</servlet-class><load-on-startup>1< /load-on-startup></servlet><servlet-mapping><servlet-name>cxfservlet</servlet-name> <url-pattern>/ws/*</url-pattern></servlet-mapping><welcome-file-list><welcome-file >index.jsp</welcome-file></welcome-file-list> 

4 , Applicationcontext-server.xml

Server-side

<import resource= "Classpath:meta-inf/cxf/cxf.xml"/><import resource= "classpath:meta-inf/cxf/ Cxf-extension-soap.xml "/><import resource=" Classpath:meta-inf/cxf/cxf-servlet.xml "/><jaxws:endpoint Id= "HelloService" implementor= "Com.test.server.HelloWorldServerImpl" address= "/helloservice"/>

Client

<import resource= "Classpath:meta-inf/cxf/cxf.xml"/><import resource= "classpath:meta-inf/cxf/ Cxf-extension-soap.xml "/><import resource=" Classpath:meta-inf/cxf/cxf-servlet.xml "/><bean id=" client "Class=" Com.test.server.IHelloWorldServer "factory-bean=" clientfactory "factory-method=" create "/><bean id=" Clientfactory "class=" Org.apache.cxf.jaxws.JaxWsProxyFactoryBean "><property name=" ServiceClass "value=" Com.test.server.IHelloWorldServer "/><property name=" Address "value=" http://localhost:8080/cxf_demo/ws/ HelloService "/></bean>

CXF There are two classes for publishing a service:

Jaxwsserverfactorybean we use this. This class is used to publish a service that can be constructed by default.

Jaxrsserverfactorybean , this class is used to publish Restful style of WebService ; Restful style is a common Get,post The request is standard and can be requested and the corresponding JSON data.

5 , Code

Server-side, publishing services

Ihelloworldserver

@WebServicepublic interface Ihelloworldserver {public string SayHello (string username);

Helloworldserverimpl

@WebService (endpointinterface = "Com.test.server.IHelloWorldServer", Servicename= "HelloService") public class Helloworldserverimpl implements ihelloworldserver{@Overridepublic string SayHello (string username) {return username + " : HelloWorld ";}}

Client

Helloworldclient

public static void Main (string[] args) {ApplicationContext context = new Classpathxmlapplicationcontext (" Applicationcontext-client.xml "); Ihelloworldserver HelloService = (ihelloworldserver) Context.getBean (" Client "); String response = Helloservice.sayhello ("Liutengteng"); SYSTEM.OUT.PRINTLN (response);}

6 , running results

Access Address: Http://localhost:8080/cxf_demo/ws

WSDL :

Client Run Results:

Summarize

From the simple example above we can easily see that the remote call is through the server-side Publishing Service, the client calls. The published WSDL is presented in XML form, XML parsing, and SOAP is XML-based. Because XML is common in various languages, Web service implements cross-platform, cross-language.
