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：
