基于Xfire SOAP Header的WebService安全验证xfire服务端，jax-ws和xfire两种客户端

WebSerice是一种开放的web服务，任何人都可以访问，但我们有时候需要考虑只有付费用户才能使用WS,所以，我们就需要对WS加入安全验证机制，当然，可以利用防火墙的IP过滤，web应用的配置从最外层去隔离非法用户，但在内层，我们也可以使用SOAP Header的方式，由客户端发送验证数据，服务端验通过后基WS访问权限

首先根据我的这篇Blog

配置WS Server和WS Client，其中Client端的测试代码类名由Client改为ClientTest,因为我们要用到Xfire的一个名为Client的类

首先我们编写服务端验证类继承AbstractHandler

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);

}

xfire客户端实现身份

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);

}

为ClientTest.java加入以下代码

       public static void main(String[] args) {
       WebsiteAuthentClient Website = new WebsiteAuthentClient();
        WebsiteAuthentPortType service = Website.getWebsiteAuthentHttpPort();
       XFireProxy proxy = (XFireProxy)Proxy.getInvocationHandler(service);
      Client client = proxy.getClient();
      client.addOutHandler(new ClientAuthenticationHandler("abcd1","1234"));
       service.test("sdf");
   }

等等，还没有完，修改Services.xm为WS绑定Handler

<? xml version="1.0" encoding="UTF-8" ?>

< beans >

< service xmlns ="http://xfire.codehaus.org/config/1.0" >

< name > HelloService </ name >

< namespace > http://test/HelloService </ namespace >

< serviceClass > test.IHelloService </ serviceClass >

< implementationClass > test.HelloServiceImpl </ implementationClass >

< inHandlers >

< handler handlerClass ="test.AuthenticationHandler" ></ handler >

</ inHandlers >

</ service >

</ beans >

这样我们就完成了编码，下面启动tomcat，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WS,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

如果不在CientTest加以下增加Heade则会有以下异常

XFireProxy proxy = (XFireProxy)Proxy.getInvocationHandler(service);
Client client = proxy.getClient();
client.addOutHandler(new ClientAuthenticationHandler("abcd1","1234"));

Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. nested exception is org.codehaus.xfire.fault.XFireFault: 请求必须包含验证信息
