Activiti学习笔记4 — 流程实例化

private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

2、启动流程

    流程启动后会更新以下二张表：act_ru_execution和act_ru_task各产生一条记录 

1 // 获取服务对象的实例
2         RuntimeService runtimeService = processEngine.getRuntimeService();
3 
4         String processDefinitionKey = "leaveflow";
5         // 自动执行与Key相对应的流程的最高版本
6         ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey);
7 
8         logger.info("Id:" + processInstance.getId());
9         logger.info("ActivitiId:" + processInstance.getActivityId());
