描述
activiti中內(nèi)嵌子流程(call activity)是新啟動一個流程，該子流程和父流程沒有父子關(guān)系。該子流程的proc_inst_id_的parent_id_是空的介袜。如果想要獲取父流程的proc_inst_id_蛮粮，可以通過執(zhí)行環(huán)境(id_)和父執(zhí)行環(huán)境(super_exec_)來獲取。上述字段都是act_ru_execution表中颤诀。

ExecutionEntity executionEntity = (ExecutionEntity) execution;
ExecutionEntity processInstance = executionEntity.getProcessInstance();

String superProcessInstanceId = superExecution.getProcessInstanceId();
log.info("processInstanceId:{},pid:{}", processInstance.getId(), superProcessInstanceId);

表中第三條記錄是流程實(shí)例ID為2830018，執(zhí)行環(huán)境ID為2830018的子流程記錄崖叫。該記錄的父執(zhí)行環(huán)境ID為2830016遗淳，通過父執(zhí)行環(huán)境ID定位到第二條記錄，從而獲取父流程實(shí)例ID2830001
