webservice 第一讲

1.服务器的建立
1.1 创建接口

package org.first.service;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

@WebService
public interface IMyService {
	
	@WebResult(name="addResult")
	public int add(@WebParam(name="a")int a,@WebParam(name="b")int b);
	
	@WebResult(name="minusResult")
	public int minus(@WebParam(name="a")int a,@WebParam(name="b")int b);
	
	@WebResult(name="loginUser")
	public User login(@WebParam(name="username")String username,@WebParam(name="password")String password);

}

1.2 创建接口实现类

package org.first.service;

import javax.jws.WebService;

@WebService(endpointInterface="org.first.service.IMyService")
public class MyServiceImpl 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;
	}

	@Override
	public User login(String username, String password) {
		System.out.println(username+" is logining");
		User user = new User();
		user.setId(1);
		user.setUsername(username);
		user.setPassword(password);
		return user;
	}

}

1.3 开启服务

package org.first.service;

import javax.xml.ws.Endpoint;

public class MyServer {

	public static void main(String[] args) {
		String address = "http://localhost:8888/ns";
		Endpoint.publish(address, new MyServiceImpl());
	}

}

2 客户端建立

package org.first.service;

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

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

public class TestClient {
	public static void main(String[] args) {
		try {
			//创建访问wsdl服务地址的url
			URL url = new URL("http://localhost:8888/ns?wsdl");
			//通过Qname指明服务的具体信息
			QName sname = new QName("http://service.first.org/", "MyServiceImplService");
			//创建服务
			Service service = Service.create(url,sname);
			//实现接口
			IMyService ms = service.getPort(IMyService.class);
			System.out.println(ms.login("wxh", "wr"));
			//以上服务有问题，依然依赖于IMyServie接口
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
	}
}
