WEBSERVICE快速入門的示例：

首先定義介面：

package com.whaty.platform.ws.server;

import javax.jws.WebService;

/**
 * @className:IMyservice.java
 * @Desc:定義：SEI service endpoint interface
 * @author:lizhuang
 * @createTime:2012-12-21 上午12:57:18
 */
//JAX-WS註解，表示java api xml for webservice。JDK自帶API的XML格式的webservice
@WebService
public interface IMyservice {
	
	int add(int a, int b);

	int minus(int a, int b);
}
 

package com.whaty.platform.ws.server;

import javax.jws.WebService;

/** 
 * @className:MyServiceImpl.java
 * @Desc:定義：SIB service implemention bean
 * @author:lizhuang
 * @createTime:2012-12-21 上午01:01:22
 */

//endpointInterface指定接入點介面：介面必須存在
@WebService(endpointInterface="com.whaty.platform.ws.server.IMyservice")
public class MyServiceImpl implements IMyservice {

	public int add(int a, int b) {
		System.out.println("a+b="+(a+b));
		return a+b;
	}

	public int minus(int a, int b) {
		System.out.println("a-b="+(a-b));
		return a-b;
	}

}
 

package com.whaty.platform.ws.server;

import javax.xml.ws.Endpoint;

/**
 * @className:MyServer.java
 * @Desc:釋出服務
 * @author:lizhuang
 * @createTime:2012-12-21 上午01:02:39
 */
public class MyServer {
	public static void main(String[] args) {
		//訪問方式：http://localhost:7777/tudou?wsdl
		String address="http://localhost:7777/tudou";
		Endpoint.publish(address, new MyServiceImpl());
	}
}
 

http://localhost:7777/tudou?wsdl

下面我們建立客戶端訪問：

package com.whaty.platform.ws.client;

import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.ws.Service;

import com.whaty.platform.ws.server.IMyservice;

/**
 * @className:MyClient.java
 * @Desc:訪問釋出的服務
 * @author:lizhuang
 * @createTime:2012-12-21 上午01:23:57
 */
public class MyClient {
	public static void main(String[] args) {

		try {
			//服務WSDL Document的地址
			URL url = new URL("http://localhost:7777/tudou?wsdl");
			//Qnameqname是qualified name 的簡寫
			//2.構成：由名字空間(namespace)字首(prefix)以及冒號(:),還有一個元素名稱構成
			//由釋出的wsdl可知namespace為http://server.ws.platform.whaty.com/，
			QName qname=new QName("http://server.ws.platform.whaty.com/","MyServiceImplService");
			Service service=Service.create(url, qname);
			IMyservice ms=service.getPort(IMyservice.class);
			ms.add(1, 4);
			ms.minus(1, 4);
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
	}
}

a+b=5
a-b=-3
