Xfire soapHeader的WebService权限控制forjava

研究webservice有一段时间了，觉得用soapHeader来控制访问比较简单，特贴出代码以供大家分享

1.我们可以做一个很简单的ws测试，服务端的接口代码如下：

package ws;
//Generated by MyEclipse

public interface HelloWord {
    public String example(String message);

}

 

实现类：

package ws.impl;

import ws.HelloWord;
public class HelloWordImpl implements HelloWord {

    public String example(String message) {
        System.out.println(message);
        return message;
    }
}

 服务端的验证类：

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test@test的用户为授权用户
               if(username.equals("test") && password.equals("test"))
                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);
            }
     }
}

 

这样服务端的任务就算完成，客户端调用是也需要一个授权信息，如下：

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);
     }
}

 

然后就是客户端的调用了，其代码如下

import java.net.URL;
public class HelloWorkClient {

     public static void main(String[] args) throws  Exception {
            String wsdlUrl="http://127.0.0.1:8080/testWS/services/helloWord?wsdl";
            org.codehaus.xfire.client.Client client = new org.codehaus.xfire.client.Client(new  URL(wsdlUrl));
            <span style="color: #333333; #ffffff;">client.addOutHandler(new ClientAuthenticationHandler("abcd","1234"));</span>
            Object[] obj = client.invoke("example",new Object[]{"调用成功"});
            System.out.println(obj[0]);

        }
}

client.addOutHandler表示客户端调用服务端的验证码，你如果没有这行则无法调用，另外就是service.xml的配置文件必须要配置soapHeader，代码如下：

<service  xmlns="http://xfire.codehaus.org/config/1.0">
        <name>helloWord</name>
        <serviceClass>ws.HelloWord</serviceClass>
        <implementationClass>ws.impl.HelloWordImpl</implementationClass>
        <inHandlers>
         <handler  handlerClass ="ws.other.AuthenticationHandler" ></handler >
         </inHandlers>
        <style>wrapped</style>
        <use>literal</use>
        <scope>application</scope>
    </service>

 

这样，一个完整的测试权限的例子就算完成了。
