每次啟動一個流程，這個流程就是一個全新的流程實例，比如每次運行下面的程序時就會創建一個新的流程實例。 ```java @Test public void runtimeProcess() { //獲取ProcessEngine ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); //獲取RuntimeService RuntimeService runtimeService = processEngine.getRuntimeService(); //根據流程key啟動對應的流程，創建流程實例 ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("evectionProcess"); //流程部署id：1 log.info("流程部署id：{}", processInstance.getDeploymentId()); //流程定義id：evectionProcess:1:4 log.info("流程定義id：{}", processInstance.getProcessDefinitionId()); //流程實例id：2501 log.info("流程實例id：{}", processInstance.getId()); } ```
