通过客户端编程的方式调用webservice

通过客户端编程的方式调用webservice其实与通过jdk调用webservice的方式其实是一样的。在4种调用webservice的方式中推荐使用

通过jdk来调用webservice的那一种方式，因为其实他才是最简单的。

1、服务器端的代码和通过jdk调用webservice的方式是一样的。

2、客户端代码的书写

package com.njupt.webservice.client;

import java.net.URL;

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

import com.njupt.webservice.HelloService;

public class App {

	public static void main(String[] args) throws Exception {
		URL wsUrl = new URL("http://127.0.0.1:6790/hello?wsdl");
	    
		//QName()的第一个参数是wenservice(服务端)所在包的倒序,在此作为命名空间
		Service s = Service.create(wsUrl,new QName("http://webservice.njupt.com/","HelloServiceService"));
		
		//注意,getPort()方法的第二个参数是HelloServicePort,二Service.create()的第二个参数是HelloServiceService.
		//不要写错了,二者都可以在这个webservice的wsdl文件中找到
		HelloService hs = s.getPort(new QName("http://webservice.njupt.com/","HelloServicePort"),HelloService.class);
		
		String ret = hs.sayHello("章泽天");
		
		System.out.println(ret);
	}
}

在最后附上这一个webservice的wsdl的代码
