[WebService]之JWS_1

创建JWS项目步骤:

1:创建接口

2:创建实现类

3:开启服务

 

1:编写接口

@WebService

public interface IMyService {

    

    public int add(int a,int b);

    

    public int minus(int a,int b);

}

　　

1:编写接口实现类

@WebService(endpointInterface = "org.wnj.service.IMyService")  //指定接口包名类包

public class MyServiceImpl implements IMyService {

    

    /** {@inheritDoc} */

    

    @Override

    public int add(int a, int b) {

        System.out.println(a + "+" + b + "=" + (a + b));

        return a + b;

    }

    

    /** {@inheritDoc} */

    

    @Override

    public int minus(int a, int b) {

        System.out.println(a + "-" + b + "=" + (a - b));

        return a - b;

    }

    

}

　　

 

//3:启动服务

public class MyServer {

    

    public static void main(String[] args) {

        String address = "http://localhost:8888/ns";  

        Endpoint.publish(address, new MyServiceImpl());  

    }

}

 

 //4:编写客户端

 

 /** <一句话功能简述>

     * <功能详细描述>

     * @param args

     */

    public static void main(String[] args) {



        try {

            //创建访问wsdl服务的地址

            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.wnj.org/","MyServiceImplService");

            //创建服务

            Service service = Service.create(url, sname);

            //实现接口(最大的问题需要知道接口)

            IMyService ms = service.getPort(IMyService.class);

            System.out.println(ms.add(1, 2));

        }

        catch (MalformedURLException e) {

            e.printStackTrace();

        }

    }

WSDL标签解释

type:用来定义的传输类型,用SOAP(Simple Object Access Protool协议指定参数

mesage:用来传输SOAP消息

portType:指定服务器的接口，并且通过operation绑定方法名及相应的in,out的消息，其中in表示入参，out表示出参

binding:指定传输消息所使用的格式

service:指定服务所发布的信息
