从.wsdl为java生成Web服务客户端安全策略

Question

我一直在研究如何从.wsdl文件实现Web服务客户端策略。

Web服务的策略涉及使用带有必要密钥的.jks文件的签名和加密（用于签名的非对称privateKey和用于加密的对称privateKey）。策略是：username：oracle / wss10_username_token_with_message_protection_service_policy。

我可以使用wsimport工具为java（或使用cxf或axis2）创建.xsd文件（请求，响应和服务对象）。我无法解决的是如何制定正确的政策。

有没有办法从.wsdl自动生成策略，或者我必须自己生成它们

用户名：oracle / wss10_username_token_with_message_protection_service_policy通过spring ws解决：

<!-- == Ougoing interceptor == -->
<bean id="loginOutgoingWss4jSecurityInterceptor" class="org.springframework.ws.soap.security.wss4j2.Wss4jSecurityInterceptor">
    <property name="securementActions" value="Timestamp Signature Encrypt" />

    <!--  == Set Outgoing Signature properties == -->
    <property name="securementUsername" value="alias"/>
    <property name="securementPassword" value="aliasPass"/>
    <property name="securementSignatureKeyIdentifier" value="DirectReference"/>
    <property name="securementSignatureCrypto" ref="cryptoFactoryBean" />
    <property name="securementSignatureParts" value="{Element}{}Body;{Element}{http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd}Timestamp;" />

    <!--  == Set Outgoing Encryption properties == -->
    <property name="securementEncryptionUser" value="alias"/> 
    <property name="securementEncryptionCrypto" ref="cryptoFactoryBean" />
    <property name="securementEncryptionKeyIdentifier" value="DirectReference"/>
    <property name="securementEncryptionParts" value="{Content}{}Body;" />
</bean>

<!-- == Incoming interceptor == -->
 <bean id="loginIncomingWss4jSecurityInterceptor" class="org.springframework.ws.soap.security.wss4j2.Wss4jSecurityInterceptor">
    <property name="validationActions" value="Timestamp Signature Encrypt" />

    <!--  == Set Validations Response, This validate signature and decrypts response == -->
    <property name="validateResponse" value="true" />

    <!-- The lower operation validation. Less time consume-->
    <property name="validateRequest" value="false" />
    <property name="enableSignatureConfirmation" value="false"/>

    <!--  == Set Incoming Signature/Decryption keystore == -->
    <property name="validationDecryptionCrypto" ref="cryptoFactoryBean" />
    <property name="validationSignatureCrypto" ref="cryptoFactoryBean" />

    <!-- Sets the {@link org.apache.ws.security.WSPasswordCallback} handler to use when validating messages -->
    <property name="validationCallbackHandler">
        <bean class="org.springframework.ws.soap.security.wss4j2.callback.KeyStoreCallbackHandler">
            <property name="privateKeyPassword" value="aliasPass"/>
        </bean>
    </property> 
 </bean>

如果您在wsdl中使用WS-SecurityPolicy（1.1或更高版本）中的策略，则无需生成策略，也无需在客户端使用Apache CXF生成策略。借助WS-SecurityPolicy，CXF的安全运行时是策略驱动的。

1）您使用wsdl2java命令行工具或Maven cxf-codegen-plugin（wsdl2java目标）遵循CXF的WSDL优先方法来生成客户端代码。这在CXF doc的How to develop a client中有所描述。

2）遵循CXF关于WS-SecurityPolicy usage的文档，您可以使用JAX-WS API（在客户端的RequestContext上）或Spring XML配置为您要使用的wsdl端口配置客户端安全性属性。对于可能的属性列表，有通用的XML security和WS-Security-specific。使用Spring XML for UsernameToken策略的示例（来自Glen Mazza's blog samples）：

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:jaxws="http://cxf.apache.org/jaxws"
   xsi:schemaLocation="http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://cxf.apache.org/jaxws 
   http://cxf.apache.org/schemas/jaxws.xsd">
<jaxws:client name="{http://www.example.org/contract/DoubleIt}DoubleItPort" createdFromAPI="true">
        <!-- Use this for the UsernameToken Symmetric Binding w/X.509 for secret key derivation -->
        <jaxws:properties>
            <entry key="ws-security.username" value="alice"/>        
            <entry key="ws-security.callback-handler" value="client.ClientPasswordCallback"/>        
            <entry key="ws-security.encryption.properties" value="clientKeystore.properties"/>
            <entry key="ws-security.encryption.username" value="myservicekey"/>
        </jaxws:properties>

        <!-- Use this for the UsernameToken Symmetric Binding w/UT password for secret key derivation -->
        <!--jaxws:properties>
            <entry key="ws-security.username" value="alice"/>        
            <entry key="ws-security.callback-handler" value="client.ClientPasswordCallback"/>        
        </jaxws:properties-->
</jaxws:client>
</beans>

把它放在类路径上的/cxf.xml中。警告：该示例使用CallbackHandler子类（在此示例中为client.ClientPasswordCallback）来提供密码。所以你需要提供自己的实现。

3）回到CXF doc的How to develop a client - 最后一部分 - 在应用程序代码中，使用带有参数的JAX-WS API初始化客户端：a）具有WS-SecurityPolicy策略的WSDL（URL）的位置（您已经拥有它，如据我所知）; b）客户端使用的服务和端口的QNames，如WSDL中所定义：

final Service service = Service.create(wsdlLocation, SERVICE_QNAME);
final DoubleItPortType transportPort = service.getPort(PORT_QNAME, DoubleItPortType.class);

4）确保在运行时在类路径上有cxf-rt-ws-policy和cxf-rt-ws-security模块以启用WS-SecurityPolicy支持。
