Apache CXF之helloworld

1.首先去http://cxf.apache.org/download.html下载CXF所需要的jar，我下载是apache-cxf-2.3.4.zip这个包。

2.建一个java project，并把相关的jar文件添加到classpath路径下.

cxf-2.3.4.jar
jetty-continuation-7.3.1.v20110307.jar
jetty-http-7.3.1.v20110307.jar
jetty-io-7.3.1.v20110307.jar
jetty-server-7.3.1.v20110307.jar
jetty-util-7.3.1.v20110307.jar
servlet-api.jar
wsdl4j-1.6.2.jar
XmlSchema-1.4.7.jar

3.创建一个接口

package com.cxf.service;

public interface HelloWorldCxfService {
    
    String sayHello(String username);
}

4.创建该接口的实现类

package com.cxf.service;

public class HelloWorldCxfServiceImpl implements HelloWorldCxfService {

    public String sayHello(String username) {
        return "Hello,"+username;
    }
}

5.发布webservice

package com.cxf.server;

import org.apache.cxf.frontend.ServerFactoryBean;

import com.cxf.service.HelloWorldCxfService;
import com.cxf.service.HelloWorldCxfServiceImpl;

public class Server {

	public static void main(String[] args) {
		HelloWorldCxfServiceImpl cxfServiceImpl= new HelloWorldCxfServiceImpl();
		ServerFactoryBean factoryBean=new ServerFactoryBean();
		factoryBean.setAddress("http://localhost:8080/hello");
		factoryBean.setServiceClass(HelloWorldCxfService.class);
		factoryBean.setServiceBean(cxfServiceImpl);
		factoryBean.create();
	}

}

运行Server，注意不要关闭，在控制台会打印如下信息：

2011-5-11 14:25:30 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://service.cxf.com/}HelloWorldCxfService from class com.cxf.service.HelloWorldCxfService
2011-5-11 14:25:30 org.apache.cxf.endpoint.ServerImpl initDestination
信息: Setting the server's publish address to be http://localhost:8080/hello
2011-05-11 14:25:30.750:INFO::jetty-7.3.1.v20110307
2011-05-11 14:25:30.859:INFO::Started SelectChannelConnector@localhost:8080
2011-05-11 14:25:30.875:INFO::started o.e.j.s.h.ContextHandler{,null}

6.客户端调用

package com.cxf.server;

import org.apache.cxf.frontend.ClientProxyFactoryBean;

import com.cxf.service.HelloWorldCxfService;

public class Client {
    
    public static void main(String[] args) {
        ClientProxyFactoryBean factoryBean=new ClientProxyFactoryBean();
        factoryBean.setAddress("http://localhost:8080/hello");
        factoryBean.setServiceClass(HelloWorldCxfService.class);
        HelloWorldCxfService worldCxfService=(HelloWorldCxfService) factoryBean.create();
        System.out.println(worldCxfService.sayHello("张三"));
    }
}

运行Client代码，控制台打印如下信息：

2011-5-11 14:25:35 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://service.cxf.com/}HelloWorldCxfService from class com.cxf.service.HelloWorldCxfService
Hello,张三


        到此，我们的webservice，已经成功调用了。大家是不是迫不及待的想看下wsdl文件是啥样的呢？
在浏览器中输入http://localhost:8080/hello?wsdl，即可看到wsdl文件了。其中http://localhost:8080/hello部分为代码里指定的Address。
        wsdl文件信息：

−
<wsdl:types>
−

最后，附上源码
