我在启动时加载我的 spring bean 文件。它包含以下内容：
<aop:config>
<aop:aspect id="aspectLoggging" ref="logAspect">
<!-- @Before -->
<aop:pointcut id="pointCutBefore"
expression="execution(* org.server.RequestProcessor.create(..))" />
<aop:before method="advice" pointcut-ref="pointCutBefore" />
</aop:aspect>
</aop:config>
<bean id="serviceImplementation" class="org.server.RequestProcessor">
<constructor-arg>
<ref bean="daoFactory"/>
</constructor-arg>
<property name="server">
<ref bean="server"/>
</property>
</bean>
现在从 services.xml 中，我已将“serviceImplementation”bean 声明为 SpringBeanName。其内容如下：-
<parameter name="ServiceObjectSupplier">org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier</parameter>
<parameter name="SpringBeanName">serviceImplementation</parameter>
<parameter name="ServiceClass" locked="false">org.server.RequestProcessor</parameter>
<parameter name="LoadOnStartup">true</parameter>
<operation name="create">
<messageReceiver class="org.apache.axis2.receivers.RawXMLINOutMessageReceiver"/>
<actionMapping>http://www.example.com/ManagementServices/create</actionMapping>
</operation>
因此，当“创建”操作将被调用时。方面类将尝试拦截 org.server.RequestProcessor.create(..)
但我无法实现这一点，我在服务器启动时收到以下错误：-
2012-07-26 14:25:28,616 ERROR [ContextLoader] Context initialization failed
