jws webservice code

1、服务器端建立

1.1、创建接口 
[java] view plaincopy 
@WebService  
public interface IWebService {  
    int add(int a, int b);  
    int subtract(int a, int b);  
}  
1.2、创建实现类 
[java] view plaincopy 
@javax.jws.WebService(endpointInterface = "org.gwr.service.IWebService")  
public class WebService implements IWebService {  
    @Override  
    public int add(int a, int b) {  
        System.out.println(a + "+" + b + "=" + (a + b));  
        return a + b;  
    }  
    @Override  
    public int subtract(int a, int b) {  
        System.out.println(a + "-" + b + "=" + (a - b));  
        return a - b;  
    }  
}  
1.3、部署服务 
[java] view plaincopy 
public class ReleaseService {  
    public static void main(String[] args) {  
        String address = "http://localhost:8888/ns";  
        Endpoint.publish(address, new WebService());  
    }  
}

2、客户端建立

调用webService 
[java] view plaincopy 
public class CallService {  
    public static void main(String[] args) {  
        // 创建访问wsdl服务地址的url  
        try {  
            URL url = new URL("http://localhost:8888/ns?wsdl");  
            // 通过Qname指明服务的具体信息  
            QName sname = new QName("http://service.gwr.org/",  
                    "WebServiceService");  
            // 创建服务  
            Service service = Service.create(url, sname);  
            // 实现接口  
            IWebService ms = service.getPort(IWebService.class);  
            System.out.println(ms.add(12, 33));  
        } catch (MalformedURLException e) {  
            e.printStackTrace();  
        }  
    }  
}
