XFire实现身份验证(基于Xfire SOAP Header的WebService安全验证)

一、创建web services 工程(XFire)，和平时的一样。
二、加入身份验证功能
1、首先编写服务端验证类，继承AbstractHandler类
package test;
import org.codehaus.xfire.MessageContext;
import org.codehaus.xfire.handler.AbstractHandler;
import org.jdom.Element;

public class AuthenticationHandler extends AbstractHandler {

public void invoke(MessageContext cfx) throws Exception {
   if (cfx.getInMessage().getHeader() == null) {
    throw new org.codehaus.xfire.fault.XFireFault("请求必须包含验证信息",
      org.codehaus.xfire.fault.XFireFault.SENDER);
   }
   Element token = cfx.getInMessage().getHeader().getChild(
     "AuthenticationToken");
   if (token == null) {
    throw new org.codehaus.xfire.fault.XFireFault("请求必须包含身份验证信息",
      org.codehaus.xfire.fault.XFireFault.SENDER);
   }

   String username = token.getChild("Username").getValue();
   String password = token.getChild("Password").getValue();
   try {
    // 进行身份验证 ，只有abcd@1234的用户为授权用户
    if (username.equals("abcd") && password.equals("1234"))
     // 这语句不显示
     System.out.println("身份验证通过");
    else
     throw new Exception();
   } catch (Exception e) {
    throw new org.codehaus.xfire.fault.XFireFault("非法的用户名和密码",
      org.codehaus.xfire.fault.XFireFault.SENDER);
   }
}
}
2、Client构造授权信息
package test;
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、修改services.xml为web services绑定Handler
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service xmlns="http://xfire.codehaus.org/config/1.0">
   <name>Hello</name>
   <namespace>http://test/HelloService</namespace>
   <serviceClass>test.IHello</serviceClass>
   <implementationClass>test.HelloImpl</implementationClass>
   <inHandlers>
   <handler handlerClass ="test.AuthenticationHandler" ></handler >
   </inHandlers>
   <style>wrapped</style>
   <use>literal</use>
   <scope>application</scope>
</service>
</beans>
4、新建一个类ClientTest，用来测试
package 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;

public class ClientTest {

/**
* @param args
*/
public static void main(String[] args) {
   // TODO Auto-generated method stub
   try {
    Service serviceModel = new ObjectServiceFactory().create(IHello.class);
    IHello service = (IHello) new XFireProxyFactory().create(serviceModel,
        "http://dracom-d1514b82:8080/web_services3/services/Hello");   
    XFireProxy proxy = (XFireProxy)Proxy.getInvocationHandler(service);
    Client client = proxy.getClient();
    //发送授权信息
    client.addOutHandler(new ClientAuthenticationHandler("abcd","1234"));
    //输出调用web services方法的返回信息
    System.out.println(service.getMessage("你好aaa"));
   } catch (MalformedURLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   } catch (IllegalArgumentException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
}
}
三、这样我们就完成了编码，下面启动web services，运行客户端代码，本文为abcd@1234位授权用户，
使用abcd@1234,可以正常访问web services,如果用错误帐号，则会有以下异常:
Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: 非法的用户名和密码

at org.codehaus.xfire.client.XFireProxy.invoke(XFireProxy.java:57)
at $Proxy0.getMessage(Unknown Source)
at test.ClientTest.main(ClientTest.java:24)

如果不在CientTest加以下Heade则会有以下异常:
    XFireProxy proxy = (XFireProxy)Proxy.getInvocationHandler(service);
    Client client = proxy.getClient();
    //发送授权信息
    client.addOutHandler(new ClientAuthenticationHandler("abcd1","1234"));
