6.流程执行历史记录

1.查询历史流程实例

    /**查询历史流程实例*/
    @Test
    public void findHistoryProcessInstance(){
        String processInstanceId = "2001";
        HistoricProcessInstance hpi = processEngine.getHistoryService()//与历史数据（历史表）相关的Service
                .createHistoricProcessInstanceQuery()//创建历史流程实例查询
                .processInstanceId(processInstanceId)//使用流程实例ID查询
                .orderByProcessInstanceStartTime().asc()
                .singleResult();
        System.out.println(hpi.getId()+"    "+hpi.getProcessDefinitionId()+"    "+hpi.getStartTime()+"    "+hpi.getEndTime()+"     "+hpi.getDurationInMillis());
    }

2.查询历史活动

    /**查询历史活动*/
    @Test
    public void findHistoryActiviti(){
        String processInstanceId = "2001";
        List<HistoricActivityInstance> list = processEngine.getHistoryService()//
                .createHistoricActivityInstanceQuery()//创建历史活动实例的查询
                .processInstanceId(processInstanceId)//
                .orderByHistoricActivityInstanceStartTime().asc()//
                .list();
        if(list!=null && list.size()>0){
            for(HistoricActivityInstance hai:list){
                System.out.println(hai.getId()+"   "+hai.getProcessInstanceId()+"   "+hai.getActivityType()+"  "+hai.getStartTime()+"   "+hai.getEndTime()+"   "+hai.getDurationInMillis());
                System.out.println("#####################");
            }
        }
    }

3.查询历史任务

    /**查询历史任务*/
    @Test
    public void findHistoryTask(){
        String processInstanceId = "2001";
        List<HistoricTaskInstance> list = processEngine.getHistoryService()//与历史数据（历史表）相关的Service
                .createHistoricTaskInstanceQuery()//创建历史任务实例查询
                .processInstanceId(processInstanceId)//
                .orderByHistoricTaskInstanceStartTime().asc()
                .list();
        if(list!=null && list.size()>0){
            for(HistoricTaskInstance hti:list){
                System.out.println(hti.getId()+"    "+hti.getName()+"    "+hti.getProcessInstanceId()+"   "+hti.getStartTime()+"   "+hti.getEndTime()+"   "+hti.getDurationInMillis());
                System.out.println("################################");
            }
        }
    }

4.查询历史流程变量

    /**查询历史流程变量*/
    @Test
    public void findHistoryProcessVariables(){
        String processInstanceId = "2001";
        List<HistoricVariableInstance> list = processEngine.getHistoryService()//
                .createHistoricVariableInstanceQuery()//创建一个历史的流程变量查询对象
                .processInstanceId(processInstanceId)//
                .list();
        if(list!=null && list.size()>0){
            for(HistoricVariableInstance hvi:list){
                System.out.println(hvi.getId()+"   "+hvi.getProcessInstanceId()+"   "+hvi.getVariableName()+"   "+hvi.getVariableTypeName()+"    "+hvi.getValue());
                System.out.println("###############################################");
            }
        }
    }
