本文提供了使用Java开发WebService的详细步骤，包括接口定义、实现类编写、服务发布及客户端调用。

编程发布WebService方式的完整例子
WS服务端:
(1)HelloWorld.java接口

package com.xxx.ws.code.server;  

import javax.jws.WebService;  

@WebService  
public interface HelloWorld {  
    String sayHi(String text);  
}

(2)实现类HelloWorldImpl.java

package com.xxx.ws.code.server.impl;  

import javax.jws.WebService;  

import com.xxx.ws.code.server.HelloWorld;  

@WebService(endpointInterface = "com.xxx.ws.code.server.HelloWorld",  
        serviceName = "HelloWorld")  
public class HelloWorldImpl implements HelloWorld {  

    public String sayHi(String text) {  
        System.out.println("sayHi called");  
        return "Hello " + text;  
    }  

}

(3)发布web service

package com.xxx.ws.code.server;  

//import javax.xml.ws.Endpoint;  

import org.apache.cxf.interceptor.LoggingInInterceptor;  
import org.apache.cxf.interceptor.LoggingOutInterceptor;  
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;  

import com.xxx.ws.code.server.impl.HelloWorldImpl;  

public class RunCXFServer {  

    protected RunCXFServer() throws Exception {  
        // START SNIPPET: publish  
        System.out.println("Starting Server");  
        HelloWorldImpl implementor = new HelloWorldImpl();  
        JaxWsServerFactoryBean svrFactory = new JaxWsServerFactoryBean();  
        svrFactory.setServiceClass(HelloWorld.class);  
        svrFactory.setAddress("http://localhost:8002/helloWorld");  
        svrFactory.setServiceBean(implementor);  
        svrFactory.getInInterceptors().add(new LoggingInInterceptor());  
        svrFactory.getOutInterceptors().add(new LoggingOutInterceptor());  
        svrFactory.create();  

        // END SNIPPET: publish  
    }  

    public static void main(String args[]) throws Exception {  
        new RunCXFServer();  
        System.out.println("Server ready...");  
    }  
}

(4)运行RunCXFServer
http://localhost:8002/helloWorld?wsdl就可以看到输出的saop envelope了.

编写客户端调用WebService

package com.xxx.ws.code.client;  

//import javax.xml.namespace.QName;  
//import javax.xml.ws.Service;  
//import javax.xml.ws.soap.SOAPBinding;  

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;  
import org.apache.cxf.interceptor.LoggingInInterceptor;  
import org.apache.cxf.interceptor.LoggingOutInterceptor;  

import com.xxx.ws.code.server.HelloWorld;  

public class RunCXFCodeClient {  
    public static void main(String args[]) throws Exception {  

        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();  
        factory.getInInterceptors().add(new LoggingInInterceptor());  
        factory.getOutInterceptors().add(new LoggingOutInterceptor());  
        factory.setServiceClass(HelloWorld.class);  
        factory.setAddress("http://localhost:8002/helloWorld");  
        HelloWorld client = (HelloWorld) factory.create();  

        String reply = client.sayHi("HI");  
        System.out.println("Server said: " + reply);  

    }  

}
