xfire实现对WebService调用接口用户验证

学习WebService进行中......

?今天总结一下前段时间学习WebServices的经验和成果......hehe

.........首先进行服务器端的编码

环境MyEclipse(服务器端)+Eclipse(客户端)+tomcat+jdk1.6+xFire

1....................创建工程

MyEclipse中集成了Xfire框架，这样给我们省了不少麻烦hh

这样得到了两个src中的文件一个接口和一个实现类

.......接口

package com.demo;
//Generated by MyEclipse

public interface IHelloService {
	
	public String example(String username);
	
}

.......实现类

package com.demo;
//Generated by MyEclipse

public class HelloServiceImpl implements IHelloService {
	
	public String example(String username) {
		return username+"我来了!";
	}
	
}

（做了点小动作....别见怪）

2................大头戏来了，用户验证监听处理器代码（大多通用直接copy吧）

package com.client;

import org.codehaus.xfire.MessageContext;
import org.codehaus.xfire.handler.AbstractHandler;
import org.jdom.Element;

public class ClientAuthenticationHandler extends AbstractHandler {

    private String username = null;

    private String password = null;

    public ClientAuthenticationHandler() { 
    }

    public ClientAuthenticationHandler(String username,String password) { 
    this.username = username; 
        this.password = password;
    }

    public void setUsername(String username) { 
        this.username = username; 
    }

    public void setPassword(String password) { 
        this.password = password; 
    }

    public void invoke(MessageContext context) throws Exception {

        //为SOAP Header构造验证信息
        Element el = new Element("header"); 
        context.getOutMessage().setHeader(el); 
        Element auth = new Element("AuthenticationToken"); 
        Element username_el = new Element("Username"); 
        username_el.addContent(username); 
        Element password_el = new Element("Password"); 
        password_el.addContent(password); 
        auth.addContent(username_el); 
        auth.addContent(password_el); 
        el.addContent(auth); 
    } 
}

3.....................服务端收尾，配置service.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
	<service>
		<name>HelloService</name>
		<serviceClass>com.demo.IHelloService</serviceClass>
		<implementationClass>
			com.demo.HelloServiceImpl
		</implementationClass>
		<!--注册监听处理器-->
		<inHandlers>
			<handler handlerClass="com.handler.AuthentificationHandler"></handler>
		</inHandlers>
		
		<style>wrapped</style>
		<use>literal</use>
		<scope>application</scope>
	</service>
</beans>

4......................服务端完成了，大家看看我的文件结构吧

5............................先给大家点惊喜，服务端配置好了，启动一下tomcat把我们的webService服务发布一下，

在浏览器中输入URL ? ? ? ? ? ??http://localhost:8080/WebService/services/HelloService?wsdl ? ?如果显示

这个xml页面的话，恭喜你，发布成功了。

6.......................下面来看一下客户端如何进行编写

首先需要把xfire的架包导入工程（放到lib文件夹下）

先看看我的文件夹结构

在这里我用了config.properties进行存放接口路径（有点大材小用）

7...........................首先需要编写的是接口文件IHelloService.java(可以直接拷贝服务器端的)

package com.imp;


public interface IHelloService {


	public String example(String username);
}

8................................然后编写PropertiesConfig用来读取properties文件

package com.test;

import java.io.FileInputStream;
import java.util.Properties;

public class PropertiesConfig {
	public static String site;

	public static String getsite() {
		Properties p = new Properties();
		try {
			 p.load(new FileInputStream("src/config.properties"));
		} catch (Exception e) {
			e.printStackTrace();
		}
		site = p.getProperty("webservice_site");
		return site;
	}

}

9........................................下面是客户端身份验证代码ClientAuthenticationHandler.java

package com.client;

import org.codehaus.xfire.MessageContext;
import org.codehaus.xfire.handler.AbstractHandler;
import org.jdom.Element;

public class ClientAuthenticationHandler extends AbstractHandler {

    private String username = null;

    private String password = null;

    public ClientAuthenticationHandler() { 
    }

    public ClientAuthenticationHandler(String username,String password) { 
    this.username = username; 
        this.password = password;
    }

    public void setUsername(String username) { 
        this.username = username; 
    }

    public void setPassword(String password) { 
        this.password = password; 
    }

    public void invoke(MessageContext context) throws Exception {

        //为SOAP Header构造验证信息
        Element el = new Element("header"); 
        context.getOutMessage().setHeader(el); 
        Element auth = new Element("AuthenticationToken"); 
        Element username_el = new Element("Username"); 
        username_el.addContent(username); 
        Element password_el = new Element("Password"); 
        password_el.addContent(password); 
        auth.addContent(username_el); 
        auth.addContent(password_el); 
        el.addContent(auth); 
    } 
}

10....................................最后来到进行我们的接口调用吧

package com.test;

import java.lang.reflect.Proxy;
import java.net.MalformedURLException;
import org.codehaus.xfire.client.*;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;

import com.client.ClientAuthenticationHandler;
import com.imp.IHelloService;

public class ClientTest {

	/**
	 * @param args
	 * @throws MalformedURLException
	 */
	public static void main(String[] args) {
		try {
			// 获取properties中的配置url地址
			String serviceUrl = PropertiesConfig.getsite();// 新增
			Service serviceModel = new ObjectServiceFactory().create(
					IHelloService.class,null,serviceUrl + "?wsdl",null);
			IHelloService service = (IHelloService) new XFireProxyFactory()
					.create(serviceModel,serviceUrl);
			XFireProxy proxy = (XFireProxy) Proxy.getInvocationHandler(service);
			Client client = proxy.getClient();
			// 发送授权信息
			client.addOutHandler(new ClientAuthenticationHandler("admin","admin"));
			// 输出调用web services方法的返回信息
			System.out.println(service.example("admin"));
		} catch (MalformedURLException e) {
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			e.printStackTrace();
		}

	}
}

好了，代码部分到此为止

如果你的服务器还没有停止，那么我们现在可以来测试了

运行客户端程序

11...........................................客户端显示

12.....................................服务器端显示
