上面的代码会自动寻找activiti.cfg.xml文件。

<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd">

  <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

    <property name="mailServerPort" value="5025" />    
  </bean>

</beans>

也会自动寻找activiti-context.xml文件，内容如下：

       xmlns:context="http://www.springframework.org/schema/context"

</beans>

activiti-context.xml和activiti.cfg.xml这两个文件任意一个均可。
