Activiti

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：

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();  

   

RuntimeService runtimeService = processEngine.getRuntimeService();  

RepositoryService repositoryService = processEngine.getRepositoryService();  

TaskService taskService = processEngine.getTaskService();  

ManagementService managementService = processEngine.getManagementService();  

IdentityService identityService = processEngine.getIdentityService();  

HistoryService historyService = processEngine.getHistoryService();  

FormService formService = processEngine.getFormService();
