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。。。
