Java 使用AES加密的CXF-WS-Security

我可能会根据以下要求使用CXF框架实现Web服务：

• 用户名令牌
• AES加密

在调用密钥之前，系统可能会将密钥传递给WS。我试图配置如下，但不工作

<bean id="logInBound" class="org.apache.cxf.interceptor.LoggingInInterceptor" />
<bean id="logOutBound" class="org.apache.cxf.interceptor.LoggingOutInterceptor" />
<jaxws:client id="helloClient" serviceClass="com.itiboss.facade.HelloWorld"        address="http://localhost:18080/spring-jpa/ws/HelloWorld">
    <jaxws:properties>
        <entry key="mtom-enabled" value="true"/>
    </jaxws:properties>
    <jaxws:inInterceptors>
        <ref bean="logInBound" />
    </jaxws:inInterceptors>
    <jaxws:outInterceptors>
        <ref bean="logOutBound" />
        <ref bean="outbound-security" />
    </jaxws:outInterceptors>
</jaxws:client>
<!-- WSS4JOutInterceptor for incorporating a UsernameToken in a SOAP --> 
<bean class="org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor" id="outbound-security">

        </map>
    </constructor-arg>
</bean>
