Activiti工作流学习（六）

前言

Activity工作流提供了很多的关于历史记录的查询，今天讲讲常用的几个方法。

四个历史查询方法

1.查询历史的流程实例

@Test
public void queryHistoryProcessInstance(){
    List<HistoricProcessInstance> historicProcessInstanceList = historyService.createHistoricProcessInstanceQuery()
                .processDefinitionKey("activiti_leave")
                .orderByProcessInstanceEndTime()
                .desc()
                .list();

    for(HistoricProcessInstance historicProcessInstance : historicProcessInstanceList){
        System.out.println("历史流程实例ID："+historicProcessInstance.getId());
        System.out.println("历史流程实例完成时间："+historicProcessInstance.getEndTime());
    }
}

2.查询当前流程实例所经历的所有活动

@Test
public void queryHistoryActivityInstance(){
    List<HistoricActivityInstance> historicActivityInstanceList = historyService.createHistoricActivityInstanceQuery()
                .processInstanceId("3001")
                .list();

    for(HistoricActivityInstance historicActivityInstance : historicActivityInstanceList){
        System.out.println("历史活动ID："+historicActivityInstance.getId());
        System.out.println("历史活动名称："+historicActivityInstance.getActivityName());
        System.out.println("办理人："+historicActivityInstance.getAssignee());
    }
}

3.查询某个办理人（结点）所经历的所有任务

@Test
public void queryHistoryTaskInstanceByAssignee(){
    List<HistoricTaskInstance> historicTaskInstanceList = historyService.createHistoricTaskInstanceQuery()
                .processDefinitionKey("activiti_leave")
                .taskAssignee("employnee")
                .list();

    for(HistoricTaskInstance historicTaskInstance : historicTaskInstanceList){
        System.out.println("历史任务ID："+historicTaskInstance.getId());
        System.out.println("历史活动名称："+historicTaskInstance.getName());
        System.out.println("结束时间："+historicTaskInstance.getEndTime());
        System.out.println("办理人："+historicTaskInstance.getAssignee());
        System.out.println("----------------------------------------------");
    }
}

4.根据流程实例的ID来查询历史流程变量

@Test
public void queryHistoryVariable(){
    List<HistoricVariableInstance> historicVariableInstanceList = historyService.createHistoricVariableInstanceQuery()
                .processInstanceId("1001")
                .list();

    for(HistoricVariableInstance historicVariableInstance : historicVariableInstanceList){
        System.out.println("流程变量ID："+historicVariableInstance.getId());
        System.out.println("变量名："+historicVariableInstance.getVariableName());
        System.out.println("变量值："+historicVariableInstance.getValue());
        System.out.println("----------------------------------------------");
    }
}
