webservice学习之一

webservice使用的主要目标是实现跨平台的可互操作行。初入门的小例子：

package com.you.webservice;

import javax.jws.WebService;

@WebService
public interface Myservice {
	public int add(int a,int b);
	public int minus(int a,int b);

}

这个接口是供服务器发布出去的接口，一定注意接口上面要表明@webservice。

package com.you.webservice;

import javax.jws.WebService;

@WebService (endpointInterface="com.you.webservice.Myservice")
public class MyserviceImpl implements Myservice{

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

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

}

package com.you.webservice;

import javax.xml.ws.Endpoint;

public class Myserver {
	public static void main(String[] args) {
		String address = "http://localhost:8000/ns";
		Endpoint.publish(address,new MyserviceImpl());
	}

}

package com.you.webservice;

import java.net.URL;

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

public class TestClient {
	public static void main(String[] args) {
		try{
			URL url = new URL("http://localhost:8000/ns?wsdl");
			QName qname = new QName("http://webservice.you.com/","MyserviceImplService");
			Service service = Service.create(url,qname);
			
			Myservice ms = service.getPort(Myservice.class);
			System.out.println(ms.add(12,33));
			
		}catch(Exception e) {
			throw new RuntimeException(e);
		}
		
		
	}

}
