起動時にSpring Beanファイルをロードしています。次の内容が含まれます。
<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>
services.xml から、「serviceImplementation」Bean を SpringBeanName として宣言しました。その内容は次のとおりです。
<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>
そのため、「作成」操作が呼び出されるとき。アスペクト クラスは org.server.RequestProcessor.create(..) をインターセプトしようとします。
しかし、私はこれを実装することができません。サーバーの起動時に次のエラーが発生します:-
