WebService Summary (i)--use CXF to advertise and invoke WebService (do not use spring)

CXF and Axis2 are two of the more popular WebService frameworks, and then I'll write a few blogs about how to use both of these frameworks.

First of all, first introduce the use of CXF.

CXF announced WebService there are many ways. Here I introduce three kinds:

1, do not use spring. Cxf himself announced WebService

2, do not use SPRING,CXF manual release WebService

3. Use Spring + CXF to publish WebService

This blog provides an example of the first approach--not using SPRING,CXF to proactively publish WebService.

Service side:

The folder structure is as follows:

Ihelloworldserver Code:

<span style= "Font-family:microsoft yahei;font-size:18px;" >package Com.test.server;public Interface Ihelloworldserver {public string SayHello (String username);} </span>

Helloworldserverimp Code:

<span style= "Font-family:microsoft yahei;font-size:18px;" >package Com.test.server;public class Helloworldserverimp implements Ihelloworldserver {@Overridepublic String SayHello (String username) {return username+ ": HelloWorld";}} </span>

These two are the most simple Java classes.

Webservlet Code:

<span style= "Font-family:microsoft yahei;font-size:18px;" >package Com.test.server;import Javax.servlet.servletconfig;import Org.apache.cxf.bus;import Org.apache.cxf.busfactory;import Org.apache.cxf.frontend.serverfactorybean;import Org.apache.cxf.transport.servlet.cxfnonspringservlet;public class Webservlet extends Cxfnonspringservlet {//private        Static final String Service_suffix = "";p rivate static final long serialversionuid = 1L;                  @Override protected void Loadbus (ServletConfig servletconfig) {Super.loadbus (servletconfig);          Bus bus = Getbus ();          Busfactory.setdefaultbus (bus);  Helloworldserverimp HelloWorld = new Helloworldserverimp ();//Implementation class Serverfactorybean Serverfactorybean = new Serverfactorybean (); Server Factory Serverfactorybean.setserviceclass (ihelloworldserver.class);//Interface Class Serverfactorybean.setaddres S ("/helloworld");         Service Request Path Serverfactorybean.setservicebean (HelloWorld); Serverfactorybean.create (); }}</span>

This servlet is used to advertise webservice when the program is deployed. The container will invoke this method on its own initiative.

Web. xml file

<span style= "Font-family:microsoft yahei;font-size:18px;" ><?xml version= "1.0" encoding= "UTF-8"? ><web-app xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns= "Http://java.sun.com/xml/ns/javaee" xmlns:web= "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi: schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id= "Webapp_ ID "version=" 3.0 "><display-name>cxf_demo</display-name><welcome-file-list><welcome-file >index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file> Index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file> Default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list> <display-name>cxf_demo</display-name><servlet><servlet-name>cxfservlet</ Servlet-name><servlet-class>com.test.server.webservlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name >cxfservlet</servlet-name><url-pattern>/ws/*</url-pattern></servlet-mapping></ Web-app></span>

By posting the above items into Tomcat, he will voluntarily announce the webservice. Enter the URL: http://localhost:8080/cxf_demo_noSpring_1/ws, you can see the published good WebService. Input URL: Http://localhost:8080/cxf_demo_noSpring_1/ws/helloWorld?

Wsdl. View the WSDL file to display correctly. Description WebService announced success.

Client

Helloworldclient Code:

<span style= "Font-family:microsoft yahei;font-size:18px;" >package Com.test.client;import Org.apache.cxf.jaxws.endpoint.dynamic.jaxwsdynamicclientfactory;public Class helloworldclient {public static void main (string[] args) {jaxwsdynamicclientfactory DCF = Jaxwsdynamicclientfactory.newinstance (); Org.apache.cxf.endpoint.Client Client = Dcf.createclient ("http:// Localhost:8080/cxf_demo_nospring_1/ws/helloworld?
WSDL ");                Object[] Objects;try {objects = Client.invoke ("SayHello", "Haitao");//Output call result System.out.println (objects[0].tostring ( ));} catch (Exception e) {e.printstacktrace ();}}} </span>

After run, the results are as follows:

At this point, the first approach is complete, and the next blog I will continue to introduce other methods.
