鑒于很多系統需要實施WS-Security的標準，我們在SpringSide中提供了XFire+WSS4J的Demo，本文介紹SpringSide中Spring+XFire+WSS4J的基本配置
[WebService Server端配置]
第一，創建一個基本的BookService
public interface BookService 
{
/** *//**
* 按書名模糊查詢圖書
*/
List findBooksByName(String name);
/** *//**
* 查找目錄下的所有圖書
*
* @param categoryId 如果category為null或“all”， 列出所有圖書。
*/
List findBooksByCategory(String categoryId);
/** *//**
* 列出所有分類.
*
* @return List<Category>，或是null。
*/
List getAllCategorys();
}
第二，接口擴展，即Extend基本的BookService，在XFire中，不同的WSS4J策略需要針對不同的ServiceClass，否則<inHandlers>里面的定義會Overlap。
public interface BookServiceWSS4JEnc extends BookService {
}
public interface BookServiceWSS4JSign extends BookService {
}
第三，配置Spring的ApplicationContext文件
<!--BookService 基類-->
<bean id="baseWebService" class="org.codehaus.xfire.spring.remoting.XFireExporter" abstract="true">
<property name="serviceFactory" ref="xfire.serviceFactory"/>
<property name="xfire" ref="xfire"/>
</bean>
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<value>
/BookService=bookService
/BookServiceWSS4J=bookServiceWSS4J
/BookServiceWSS4JEnc=bookServiceWSS4JEnc
/BookServiceWSS4JSign=bookServiceWSS4JSign
</value>
</property>
</bean>
<!--(1)BookWebService 不需要認證-->
<bean id="bookService" class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceFactory" ref="xfire.serviceFactory"/>
<property name="xfire" ref="xfire"/>
<property name="serviceBean" ref="bookManager"/>
<property name="serviceClass" value="org.springside.bookstore.plugins.xfire.service.BookService"/>
</bean>
<!-- (3)BookWebService 使用 WSS4J驗證-->
<bean id="bookServiceWSS4J" class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceBean" ref="bookManager"/>
<property name="serviceClass" value="org.springside.bookstore.plugins.xfire.service.BookServiceWSS4J"/>
<property name="inHandlers">
<list>
<ref bean="domInHandler"/>
<ref bean="wss4jInHandler"/>
<ref bean="validateUserTokenHandler"/>
</list>
</property>
</bean>
<bean id="domInHandler" class="org.codehaus.xfire.util.dom.DOMInHandler"/>
<bean id="wss4jInHandler" class="org.codehaus.xfire.security.wss4j.WSS4JInHandler">
<property name="properties">
<props>
<prop key="action">UsernameToken</prop>
<prop key="passwordCallbackClass">org.springside.bookstore.plugins.xfire.wss4j.PasswordHandler</prop>
</props>
</property>
</bean>
<bean id="validateUserTokenHandler" class="org.springside.bookstore.plugins.xfire.wss4j.WSS4JTokenHandler"/>
<!-- (4)BookWebService 使用 WSS4J驗證 Encrypt模式-->
<bean id="bookServiceWSS4JEnc" class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceBean" ref="bookManager"/>
<property name="serviceClass" value="org.springside.bookstore.plugins.xfire.service.BookServiceWSS4JEnc"/>
<property name="inHandlers">
<list>
<ref bean="domInHandler"/>
<ref bean="wss4jInHandlerEnc"/>
<ref bean="validateUserTokenHandler"/>
</list>
</property>
</bean>
<bean id="wss4jInHandlerEnc" class="org.codehaus.xfire.security.wss4j.WSS4JInHandler">
<property name="properties">
<props>
<prop key="action">Encrypt</prop>
<prop key="decryptionPropFile">org/springside/bookstore/plugins/xfire/wss4j/insecurity_enc.properties</prop>
<prop key="passwordCallbackClass">org.springside.bookstore.plugins.xfire.wss4j.PasswordHandler</prop>
</props>
</property>
</bean>
<!-- (5)BookWebService 使用 WSS4J驗證 Signature模式-->
<bean id="bookServiceWSS4JSign" class="org.codehaus.xfire.spring.remoting.XFireExporter">
<property name="serviceBean" ref="bookManager"/>
<property name="serviceClass" value="org.springside.bookstore.plugins.xfire.service.BookServiceWSS4JSign"/>
<property name="inHandlers">
<list>
<ref bean="domInHandler"/>
<ref bean="wss4jInHandlerSign"/>
<ref bean="validateUserTokenHandler"/>
</list>
</property>
</bean>
<bean id="wss4jInHandlerSign" class="org.codehaus.xfire.security.wss4j.WSS4JInHandler">
<property name="properties">
<props>
<prop key="action">Signature</prop>
<prop key="signaturePropFile">org/springside/bookstore/plugins/xfire/wss4j/insecurity_sign.properties</prop>
<prop key="passwordCallbackClass">org.springside.bookstore.plugins.xfire.wss4j.PasswordHandler</prop>
</props>
</property>
</bean>
</beans>
第四，配置insecurity_enc.properties和insecurity_sign.properties兩個密鑰庫配置文件
insecurity_enc.properties：
org.apache.ws.security.crypto.provider=org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type=jks
org.apache.ws.security.crypto.merlin.keystore.password=SpringSide
org.apache.ws.security.crypto.merlin.alias.password=SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias=david
org.apache.ws.security.crypto.merlin.file=org/springside/bookstore/plugins/xfire/wss4j/springside_private.jks
outsecurity_sign.properties：
org.apache.ws.security.crypto.provider=org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type=jks
org.apache.ws.security.crypto.merlin.keystore.password=SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias=david
org.apache.ws.security.crypto.merlin.file=org/springside/bookstore/plugins/xfire/wss4j/springside_public.jks
第五，使用SecureX生成了兩個keystore文件
springside_private.jks
別名名稱： david
創建日期： 2006-8-6
輸入類型：KeyEntry
認證鏈長度： 1
認證 [1]:

第五，新版本SpringSide需要
http://www.bouncycastle.org/download/bcprov-jdk15-133.jar
并且要配置java.security
另外,還要使用jdk加密增強策略
http://www.aygfsteel.com/openssl/archive/2006/03/08/34381.html
用戶要使用WSS4J，需要配置Bouncycastle這個SecurityProvider，否則
運行Enc模式的XFire認證的時候，會拋出異常：
org.apache.ws.security.WSSecurityException: An unsupported signature or encryption algorithm was used unsupported key
配合java.security也是非常簡單:
在最后加入BouncycastleProvider。
security.provider.1=sun.security.provider.Sun
security.provider.2=com.sun.net.ssl.internal.ssl.Provider
security.provider.3=com.sun.rsajca.Provider
security.provider.4=com.sun.crypto.provider.SunJCE
security.provider.5=sun.security.jgss.SunProvider
security.provider.6=org.bouncycastle.jce.provider.BouncyCastleProvider
[WebService Client端配置]
1，Encrypt模式的Client是在客戶端用david的公鑰加密Soap里面的usernameToken，然后發送到Web服務，Web服務用david的私鑰來驗證。這種模式需要客戶端預先知道服務器端的公鑰。
在Encrypt模式中，需要這樣配置ClientHandler：
Service serviceModel = new ObjectServiceFactory().create(BookServiceWSS4JEnc.class);
XFireProxyFactory factory = new XFireProxyFactory(getXFire());
BookService service = (BookService) factory.create(serviceModel, "xfire.local://BookServiceWSS4JEnc");
Client client = ((XFireProxy) Proxy.getInvocationHandler(service)).getClient();
//掛上WSS4JOutHandler，提供認證
client.addOutHandler(new DOMOutHandler());
Properties properties = new Properties();
configureOutProperties(properties);
client.addOutHandler(new WSS4JOutHandler(properties));
List list = service.getAllCategorys();
configureOutProperties函數負責指定Client使用何種安全策略，沒錯，使用outsecurity_enc.properties，這個properties是跟Server端的insecurity_enc.properties一起使用的。
protected void configureOutProperties(Properties config) {
config.setProperty(WSHandlerConstants.ACTION, WSHandlerConstants.ENCRYPT);
config.setProperty(WSHandlerConstants.USER, "david");
//config.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS, PasswordHandler.class.getName());
//Configuration of public key used to encrypt message goes to properties file.
config.setProperty(WSHandlerConstants.ENC_PROP_FILE,
"org/springside/bookstore/plugins/xfire/outsecurity_enc.properties");
}
outsecurity_enc.properties：
org.apache.ws.security.crypto.provider=org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type=jks
org.apache.ws.security.crypto.merlin.keystore.password=SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias=david
org.apache.ws.security.crypto.merlin.file=org/springside/bookstore/plugins/xfire/wss4j/springside_public.jks
2, Sign模式的Client同樣也是很簡單，這種模式是Client端用自己的私鑰為usernameToken簽名，服務器端用Client的公鑰來驗證簽名，因此，服務器端需要預先知道客戶端的公鑰。
對應于Encrypt模式，這里的configureOutProperties需要這樣來配置：
protected void configureOutProperties(Properties properties) {
properties.setProperty(WSHandlerConstants.ACTION,WSHandlerConstants.SIGNATURE);
// User in keystore
properties.setProperty(WSHandlerConstants.USER, "david");
// This callback is used to specify password for given user for keystore
properties.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS, PasswordHandler.class.getName());
// Configuration for accessing private key in keystore
properties.setProperty(WSHandlerConstants.SIG_PROP_FILE,"org/springside/bookstore/plugins/xfire/outsecurity_sign.properties");
properties.setProperty(WSHandlerConstants.SIG_KEY_ID,"IssuerSerial");
}
outsecurity_sign.properties：
org.apache.ws.security.crypto.provider=org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type=jks
org.apache.ws.security.crypto.merlin.keystore.password=SpringSide
org.apache.ws.security.crypto.merlin.alias.password=SpringSide
org.apache.ws.security.crypto.merlin.keystore.alias=david
org.apache.ws.security.crypto.merlin.file=org/springside/bookstore/plugins/xfire/wss4j/springside_private.jks
