Harness Offsprings to divide, parallelize and conquer

<import resource="classpath:defaultSplitterContext.xml"/>

Second, declare the delayedServiceImplementation bean, which contains the implementation we are trying to parallelize:

<bean id="delayedServiceImpl"   class="net.sourceforge.offsprings.examples.DelayedServiceImpl"/>

Third, declare the AOP Proxy bean delayedService, which acts as a foundation for the point cut interceptor. In summary, the delayedService proxy intercepts all calls to the DelayedService interface and redirects them through the splitter (bean splitterAdviceDelayedService) while using the actual implementation in delayedServiceImplementation:
  

"target" is the delayedServiceImplementation bean.
     "interceptorNames" is the splitterAdvisorDelayedService bean.

<bean id="delayedService" class="org.springframework.aop.framework.ProxyFactoryBean">
      <property name="proxyInterfaces">
        <value>net.sourceforge.offsprings.examples.DelayedService</value>
              </property>
      <property name="interceptorNames">
        <list>
          <value>splitterAdvisorDelayedService</value>
        </list>
      </property>
      <property name="target">
        <ref bean="delayedServiceImpl"/>
      </property>
    </bean>

Fourth, declare the splitterAdvisorDelayedService bean which effects the point cut to the splitter:

    Intercept all methods with names matching the "pattern" ".*"
    Apply the "advice" given by the splitterAdviceDelayedService bean

<bean id="splitterAdvisorDelayedService"    class="org.springframework.aop.support.RegexpMethodPointcutAdvisor">
      <property name="pattern">
        <value>.*</value>
      </property>
               <property name="advice">
                 <ref bean="splitterAdviceDelayedService"/>
      </property>
    </bean>

Fifth, declare the bean splitterAdviceDelayedService, which extends the default advice defaultSplitterAdvice. This bean provides the core functionality of the whole application; it's a splitter. 

We can reconfigure splitter parameters as necessary:

Some optional properties are only relevant for XML InputStream results:

<bean id="splitterAdviceDelayedService" parent="defaultSplitterAdvice">
      <property name="parallelism" value="10"/>
               <property name="batchsize" value="10"/>
              <property name = "properties">
                 <map>
                   <entry key="docPath" value="delayed_service/docs/doc" />
                   <entry key="metaPath" value="delayed_service/meta_info" />
                   <entry key="metaXSLTTemplate" value="meta.xsl" />
                 </map>
      </property>
    </bean>
