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：

[java] view plain copy

1. ProcessEngineprocessEngine=ProcessEngines.getDefaultProcessEngine();
5. RuntimeServiceruntimeService=processEngine.getRuntimeService();
7. RepositoryServicerepositoryService=processEngine.getRepositoryService();
9. TaskServicetaskService=processEngine.getTaskService();
11. ManagementServicemanagementService=processEngine.getManagementService();
13. IdentityServiceidentityService=processEngine.getIdentityService();
15. HistoryServicehistoryService=processEngine.getHistoryService();
17. FormServiceformService=processEngine.getFormService();

Activiti的服务框架如下
