webservice快速入门-使用JAX-WS注解的方式快速搭建ws服务端和客户端（一）

1.定义接口

 package org.WebService.ws.annotation;

 import javax.jws.WebService;

 @WebService
 public interface ICalculator {
     float add(float a, float b);
     float minus(float a, float b);
     float multiply(float a, float b);
     float divide(float a, float b);
 }

2.服务接口实现类

 package org.WebService.ws.annotation;

 import javax.jws.WebService;
 //endpointInterface指定接入点接口：接口必须存在 
 @WebService(endpointInterface="org.WebService.ws.annotation.ICalculator")
 public class CalculatorImpl implements ICalculator {

     @Override
     public float add(float a, float b) {
         // TODO Auto-generated method stub
         System.out.println("a+b="+(a+b));
         return a + b;
     }

     @Override
     public float minus(float a, float b) {
         // TODO Auto-generated method stub
         System.out.println("a-b="+(a-b));
         return a - b;
     }

     @Override
     public float multiply(float a, float b) {
         // TODO Auto-generated method stub
         return a * b;
     }

     @Override
     public float divide(float a, float b) {
         // TODO Auto-generated method stub
         return a / b;
     }

 }

3.发布服务

直接右键运行main方法，如果控制台没报错，多半是发布成功了，否则检查你的代码：

 package org.WebService.ws.annotation;

 import javax.xml.ws.Endpoint;

 public class Server {

     public static void main(String[] args) {
         // TODO Auto-generated method stub
         String address="http://localhost:9998/hw";
         Endpoint.publish(address, new CalculatorImpl());
     }

 }

浏览器地址栏输入：访问webservice看看是否发布成功【地址后面加上"?wsdl"】：

http://localhost:9998/hw?wsdl

浏览器显示如下：

4.创建客户端

 package org.WebService.ws.annotation;

 import java.net.MalformedURLException;
 import java.net.URL;

 import javax.xml.namespace.QName;
 import javax.xml.ws.Service;

 public class Client {

     public static void main(String[] args) throws MalformedURLException {
         // TODO Auto-generated method stub
         URL url=new URL("http://localhost:9998/hw?wsdl");
         QName qname = new QName("http://annotation.ws.WebService.org/", "CalculatorImplService");
         Service service = Service.create(url, qname);
         ICalculator cal = service.getPort(ICalculator.class);
         cal.add(1, 2);
         cal.minus(2, 1);

     }

 }

为了简化，本例中客户端和服务器是在同一个工程中的，实际上需要用Eclipse把ICalculator接口导出成jar包在导入到客户端工程中即可，客户端代码保持不变。这里也可以使用jdk提供的wsimport命令导出服务端jar包，续。。。
