/**
*
* Activiti 5.6与Spring3.0.3整合也比较简单，其基本思想就是，通过Spring的IOC容器来管理Activiti的流程引擎
* 实例以及相关服务，可见，主要是基于Activiti在与Spring整合上努力上，做好配置即可。这里基于前面的
* <receiveTask>的例子来进行.
*
*
* 为了测试方便，将获取服务的实现抽象出来，同时使用Spring自带的与JUnit4集成的工具（
* AbstractTransactionalJUnit4SpringContextTests）。我们的实现类为AbstractSpringTest，
*
*
* 本文采用activiti和spring整合中自动部署资源的功能配置如下：

/**
*
* Activiti 5.6与Spring3.0.3整合也比较简单，其基本思想就是，通过Spring的IOC容器来管理Activiti的流程引擎
* 实例以及相关服务，可见，主要是基于Activiti在与Spring整合上努力上，做好配置即可。这里基于前面的
* <receiveTask>的例子来进行.
*
*
* 为了测试方便，将获取服务的实现抽象出来，同时使用Spring自带的与JUnit4集成的工具（
* AbstractTransactionalJUnit4SpringContextTests）。我们的实现类为AbstractSpringTest，
*
*
* 本文采用activiti和spring整合中自动部署资源的功能配置如下：
* <!-- 创建流程引擎配置对象 -->
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="mailServerHost" value="localhost" />
<property name="mailServerPort" value="5025" />
<property name="jpaHandleTransaction" value="true" />
<property name="jpaCloseEntityManager" value="true" />
<property name="jobExecutorActivate" value="false" />
<!-- 使用spring的自动资源加载部署方式部署 -->
<property name="deploymentResources" value="classpath*:diagrams/*.bpmn20.xml" />
