[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
