xfire實現對WebService調用接口用戶驗證

學習WebService進行中......

今天總結一下前段時間學習WebServices的經驗和成果......hehe

.........首先進行服務器端的編碼

環境MyEclipse(服務器端)+Eclipse(客戶端)+tomcat+jdk1.6+xFire

1....................創建工程

MyEclipse中集成了Xfire框架，這樣給我們省了不少麻煩hh

這樣得到了兩個src中的文件一個接口和一個實現類

.......接口

package com.demo;
//Generated by MyEclipse

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

.......實現類

package com.demo;
//Generated by MyEclipse

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

（做了點小動作....別見怪）

2................大頭戲來了，用戶驗證監聽處理器代碼（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 {

        //爲SOAP Header構造驗證信息
        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.....................服務端收尾，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>
		<!--註冊監聽處理器-->
		<inHandlers>
			<handler handlerClass="com.handler.AuthentificationHandler"></handler>
		</inHandlers>
		
		<style>wrapped</style>
		<use>literal</use>
		<scope>application</scope>
	</service>
</beans>

4......................服務端完成了，大家看看我的文件結構吧

5............................先給大家點驚喜，服務端配置好了，啓動一下tomcat把我們的webService服務發佈一下，

在瀏覽器中輸入URL http://localhost:8080/WebService/services/HelloService?wsdl 如果顯示

這個xml頁面的話，恭喜你，發佈成功了。

6.......................下面來看一下客戶端如何進行編寫

首先需要把xfire的架包導入工程（放到lib文件夾下）

先看看我的文件夾結構

在這裏我用了config.properties進行存放接口路徑（有點大材小用）

7...........................首先需要編寫的是接口文件IHelloService.java(可以直接拷貝服務器端的)

package com.imp;


public interface IHelloService {


	public String example(String username);
}

8................................然後編寫PropertiesConfig用來讀取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........................................下面是客戶端身份驗證代碼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 {

        //爲SOAP Header構造驗證信息
        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....................................最後來到進行我們的接口調用吧

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 {
			// 獲取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();
			// 發送授權信息
			client.addOutHandler(new ClientAuthenticationHandler("admin",
					"admin"));
			// 輸出調用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，代碼部分到此爲止

如果你的服務器還沒有停止，那麼我們現在可以來測試了

運行客戶端程序
