与Spring集成：

<beansxmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd">

<!--Activiti处理引擎的配置，交由Spring管理-->

<beanid="processEngineConfiguration"class="org.activiti.spring.SpringProcessEngineConfiguration">

<!--配置数据源,和系统使用同一个数据源-->

<propertyname="dataSource"ref="dataSource"/>

<propertyname="databaseSchemaUpdate"value="true"/>

<propertyname="jobExecutorActivate"value="false"/>

<!--统一的事务管理-->

<propertyname="transactionManager"ref="transactionManager"/>

<propertyname="activityFontName"value="宋体"/>

<propertyname="labelFontName"value="宋体"/>

</bean>

<beanid="processEngine"class="org.activiti.spring.ProcessEngineFactoryBean">

<propertyname="processEngineConfiguration"ref="processEngineConfiguration"/>

</bean>



</beans>

activiti的API中，最终要的一个接口就是ProcessEngine‍‍,获取到ProcessEngine的实例，就获取了activiti体系中的所有api。重要的接口如下：

ProcessEngineprocessEngine=ProcessEngines.getDefaultProcessEngine();



RuntimeServiceruntimeService=processEngine.getRuntimeService();

RepositoryServicerepositoryService=processEngine.getRepositoryService();

TaskServicetaskService=processEngine.getTaskService();

ManagementServicemanagementService=processEngine.getManagementService();

IdentityServiceidentityService=processEngine.getIdentityService();

HistoryServicehistoryService=processEngine.getHistoryService();

FormServiceformService=processEngine.getFormService();
