Web Service实践——Xfire的ws-security用户名和密码安全验证 - helloklzs - ITeye技术网站
三、服务器端
1、PasswordHandler类,继承自avax.security.auth.callback.CallbackHandler
package com.channelsoft.hr.wssecurity;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;
import org.apache.ws.security.WSPasswordCallback;
public class PasswordHandler implements CallbackHandler {
@SuppressWarnings("unchecked")
private Map passwords = new HashMap();
@SuppressWarnings("unchecked")
public PasswordHandler() {
passwords.put("server", "serverpass");//服务器端记录的用户名和密码,可以有多个
}
public void handle(Callback[] callbacks) throws IOException,//回调接口方法
UnsupportedCallbackException {
System.out.println("Handling Password!");
WSPasswordCallback pc = (WSPasswordCallback) callbacks[0];//获取回调对象
String id = pc.getIdentifer();//获取用户名
System.out.println("id:"+id+" ,password:"+(String) passwords.get(id));
String validPw = (String)password.get(id);②-3:获取用户对应的正确密码
②-4:如果是明文密码直接进行判断
if(WSConstants.PASSWORD_TEXT.equals(callback.getPasswordType())){
String pw = callback.getPassword();
if(pw == null || !pw.equalsIgnoreCase(validPw)){
throw new WSSecurityException("password not match");
}
}else{
pc.setPassword((String) passwords.get(id));//如果是密码摘要,向回调设置正确的密码(明文密码)
}
}
2、service.xml
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>hrwebservice</name>
<namespace>com.channelsoft.hr</namespace>
<serviceClass>com.channelsoft.hr.webservice.DepartmentAndPersonInfo</serviceClass>
<implementationClass>com.channelsoft.hr.webservice.impl.DepartmentAndPersonInfoImpl</implementationClass>
<inHandlers>
<handler handlerClass="org.codehaus.xfire.util.dom.DOMInHandler" />
<bean
class="org.codehaus.xfire.security.wss4j.WSS4JInHandler" xmlns="">
<property name="properties">
<props>
<prop key="action">UsernameToken</prop>//使用用户名与密码进行安全验证
<prop key="passwordCallbackClass">
com.channelsoft.hr.wssecurity.PasswordHandler//回调类
</prop>
</props>
</property>
</bean>
</inHandlers>
</service>
</beans>

throw new WSSecurityException("password not match");

pc.setPassword((String) passwords.get(id));//如果是密码摘要,向回调设置正确的密码(明文密码)
}
}
2、客户端调用
package hr;
import java.net.MalformedURLException;
import org.codehaus.xfire.client.Client;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.security.wss4j.WSS4JOutHandler;
import org.apache.ws.security.WSConstants;
import org.apache.ws.security.handler.WSHandlerConstants;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import org.codehaus.xfire.transport.http.CommonsHttpMessageSender;
import org.codehaus.xfire.util.dom.DOMOutHandler;
import com.channelsoft.hr.webservice.DepartmentAndPersonInfo;
public class getHRInfo
{
public static void main(String args[])
{
String serviceURL = "http://localhost:8080/HRWebService/services/hrwebservice";
// 创建service对象
Service serviceModel = new ObjectServiceFactory().create(DepartmentAndPersonInfo.class);
XFireProxyFactory serviceFactory = new XFireProxyFactory();
try
{
// 获取服务对象
DepartmentAndPersonInfo service = (DepartmentAndPersonInfo) serviceFactory.create(serviceModel, serviceURL);
// 忽略http连接的超时时间,0为不设置超时时间,》=1为超时毫秒数
Client client = Client.getInstance(service);
client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "0");
//发送授权信息
// client.addOutHandler(new ClientAuthenticationHandler("abcd","1234"));
// //WS-Security
WSS4JOutHandler wsOut = new WSS4JOutHandler();
String actions =WSHandlerConstants.USERNAME_TOKEN;
wsOut.setProperty(WSHandlerConstants.ACTION, actions);//动作
wsOut.setProperty(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PASSWORD_DIGEST);//密码类型
wsOut.setProperty(WSHandlerConstants.USER, "server"); //指定用户
wsOut.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS, PasswordHandler.class.getName());//密码回调类
client.addOutHandler(new DOMOutHandler());
client.addOutHandler(wsOut);
// 调用服务
String hello = service.queryDepartmentInfo();
String hello2 = service.queryPersonnelInfo("", "", "");
System.out.println(hello);
System.out.println(hello2);
}
catch (MalformedURLException e)
{
System.out.println("错误!!!");
e.printStackTrace();
}
}
}
Web Service实践之——XFire实例
转自:http://www.javaeye.com/topic/195927
1、配置XFire运行环境:
在Tomcat下新建一个Web Applications,命名为stove,然后在其WEB-INF目录下新建一个web.xml文件,文件中输入:
Xml代码
<?xml version="1.0" encoding="GB2312">
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>XFireServlet</servlet-name>
<display-name>XFire Servlet</display-name>
<servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/servlet/XFireServlet/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>XFireServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app>
其中主要就是引入了XFireServlet,用以处理Web Service请求,并且负责提供Web Service的WSDL,如果你发布了一个名为BookService的WebService,则可以通过网址:
http://<服务器>[:端口]/<webapp名>/services/BookService
来访问这个WebService,并且通过地址:
http://<服务器>[:端口]/<webapp名>/services/BookService?WSDL 来得到这个WebService的WSDL信息。
2、开发最简单的WebService
建一个package:cn.com.pansky.webservice.xfire.study,在这个包下面新建一个接口:
Java代码
package cn.com.pansky.webservice.xfire.study;
public interface SayHiService{
public String sayHi(String name);
}
这个接口是告诉服务器你的WebService哪些方法可以被用户调用的。下面我们再来写一个SayHiService的实现类,以完成业务逻辑:
Java代码
package cn.com.pansky.webservice.xfire.study;
public class SayHiServiceImpl implements SayHiService{
public String sayHi(String name){
if(name==null){
return "连名字也不肯告诉我吗?";
}
return name+", 你吃了吗?没吃回家吃去吧。";
}
public String 不告诉你(){
return "我的名字不告诉你!";
}
} 这个类实现了sayHi方法,该方法是可以通过WebService调用访问到的。另外还实现了一个方法“不告诉你”,该方法因为没有在接口SayHiService中定义,所以不能被WebService调用到。
这个例子足够简单吧,就跟我们刚学Java时写的"Hello world"没什么两样。
到这里为止,我们做的跟平时的Java开发没啥区别,该如何来发布WebService呢?
3、把JAVA类发布为WebService:
在src目录下新建文件夹:META-INF/xfire,然后在该文件夹下新建一个XML文件:services.xml,文件内容如下:
Xml代码
<beans xmlns="http://xfire.codehaus.org/config/1.0">
<service>
<name>SayHiService</name>
<namespace>http://cn.com.pansky/SayHiService</namespace>
<serviceClass>cn.com.pansky.webservice.xfire.study.SayHiService</serviceClass>
<implementationClass>cn.com.pansky.webservice.xfire.study.SayHiServiceImpl</implementationClass>
</service>
</beans>
这个文件定义一个WebService: SayHiService,并同时定义了接口和实现类。
好了,该建的文件基本建完了,现在想办法把src下的java文件编译成class,并复制到WEB-INF/classes目录下
4、启动Tomcat,测试WebService
如果Tomcat还没配置好,抽两分钟再配一下。再把Tomcat启动起来。
再打开浏览器,输入:
http://localhost/stove/services
,服务器返回的结果如下:
Available Services:
* SayHiService [wsdl]
Generated by XFire ( http://xfire.codehaus.org )
我们看到我们的WebService已经布署成功了,我们再看看它的WSDL信息:
这个文件跟我们用Axis生成的基本是一样的。
5、享受美味的时刻
注意:客户端使用WebService接口需要jar包(wsdl4j-1.6.1.jar和xfire-all-1.2.6.jar),缺少wsdl4j-1.6.1.jar时,会出现错误:The type javax.wsdl.Definition cannot be resolved. It is indirectly referenced from required .class files
WebService这道大餐算是烹制好了,现在是享用美餐的时候了。
我们写一个客户端吃掉这道大餐:
Java代码
package cn.com.pansky.webservice.xfire.study;
import java.net.MalformedURLException;
import java.util.Map;
import org.codehaus.xfire.client.Client;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import org.codehaus.xfire.transport.http.CommonsHttpMessageSender;
public class SayHiClient{
public static void main(String args[]) {
String serviceURL = "http://localhost/stove/services/SayHiService";
Service serviceModel = new ObjectServiceFactory().create(SayHiService.class,null,"http://cn.com.pansky/SayHiService",null);
XFireProxyFactory serviceFactory = new XFireProxyFactory();
try{
SayHiService service = (SayHiService) serviceFactory.create(serviceModel, serviceURL);
//忽略http连接的超时时间,0为不设置超时时间,》=1为超时毫秒数
Client client = Client.getInstance(service);
client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "0");
String hello = service.sayHi("张山疯");
System.out.println("服务器对[张山疯] 的回答是:" + hello );
hello = service.sayHi(null);
System.out.println("服务器胡言乱语说:" + hello );
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
