Activiti 7.x 流程实例历史信息查询

//1.得到ProcessEngine对象
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

        //2.得到HistoryService
        HistoryService historyService = processEngine.getHistoryService();

        //3.得到HistoricActivitiInstanceQuery对象
        HistoricActivityInstanceQuery historicActivityInstanceQuery = historyService.createHistoricActivityInstanceQuery();

        historicActivityInstanceQuery.processInstanceId("2501");//设置流程实例的id

        //4.执行查询
        List<HistoricActivityInstance> list = historicActivityInstanceQuery
                .orderByHistoricActivityInstanceStartTime().asc().list();//排序StartTime

        //5.遍历查询结果
        for (HistoricActivityInstance instance :list){
            System.out.println(instance.getActivityId());
            System.out.println(instance.getActivityName());
            System.out.println(instance.getProcessDefinitionId());
            System.out.println(instance.getProcessInstanceId());
            System.out.println("=============================");
        }
