我已经修改了您的流量和连接网址，如下所示，现在它可以正常工作： -

<spring:beans>
         <spring:bean id="Derby_Data_Source" class="org.enhydra.jdbc.standard.StandardXADataSource" >
             <spring:property name="driverName" value="org.apache.derby.jdbc.EmbeddedDriver"/>
             <!--  <spring:property name="url" value="jdbc:derby:SOAFiap;create=true"/>   -->
           <spring:property name="url" value="jdbc:derby:memory:SOAFiap;create=true"/>  <!-- Create Database in memory -->
         </spring:bean>
 </spring:beans>
 <db:generic-config name="Generic_Database_Configuration" dataSource-ref="Derby_Data_Source" doc:name="Generic Database Configuration"/>
 <http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>

     <flow name="DerbyDBFlow1" >
          <http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/>

         <db:insert config-ref="Generic_Database_Configuration" doc:name="Database">
            <db:parameterized-query><![CDATA[INSERT INTO FIAP.ALUNO (CODIGO, NOME_ALUNO) 
VALUES (5, 'Igor Koba')]]></db:parameterized-query>
          </db:insert>

         <logger message="#[message.payload]" level="INFO" doc:name="Logger"/>
     </flow>

这对我来说很好。
