web service1简单的例子用jdk自带的类

1，建立自己的java项目my_service

2，建立包，com.hjg.service

3，创建类：

IMyService.java

package com.hjg.service;
import javax.jws.WebService;

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

加上@Webservice注解
JAX-WS注解，表示java api xml for webservice。JDK自带API的XML格式的webservice 

MyServiceImpl.java

package com.hjg.service;
import javax.jws.WebService;
@WebService(endpointInterface="com.hjg.service.IMyService")
public class MyServiceImp implements IMyService {
    @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);
    }
}

endpointInterface指定接入点接口：接口必须存在 

服务器端，MyService.java

package com.hjg.service;
import javax.xml.ws.Endpoint;
public class MyServer {
    public static void main(String[] args) {
         //访问方式：http://localhost:8888/ns?wsdl   
        String address = "http://localhost:8888/ns";
        Endpoint.publish(address, new MyServiceImp());
    }
}

客户端，MyClient.java

package com.hjg.service;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
public class MyClient {
    public static void main(String[] args) {
        try {
            //服务WSDL Document的地址  
            URL url = new URL("http://localhost:8888/ns");
            //Qnameqname是qualified name 的简写   
            //构成：由名字空间(namespace)前缀(prefix)以及冒号(:),还有一个元素名称构成   
            //由发布的wsdl可知namespace为http://service.hjg.com/，   
            QName sname = new QName("http://service.hjg.com/","MyServiceImpService");
            Service service = Service.create(url, sname);
            IMyService ms = service.getPort(IMyService.class);
            int rs = ms.add(1, 2);
            System.out.println(rs);
            
        } catch (Exception e) {
            e.printStackTrace();
        }        
    }
}

浏览器访问http:localhost:8888/ns?wsdl 返回：
