public class ActivitiHistoryTest {
    private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();


    //1、部署流程定义
    @Test
    public void deployLeave() throws Exception {
        DeploymentBuilder builder = processEngine.getRepositoryService().createDeployment();
        builder.addClasspathResource("flow/baoxiao.bpmn");
        builder.addClasspathResource("flow/baoxiao.png");
        builder.name("报销流程部署");
        Deployment deploy = builder.deploy();
        System.out.println("deploy.getId()==" + deploy.getId());
    }


    //2、根据流程定义的key启动流程实例,启动版本version最高的
    @Test
    public void startProcessInstanceByKey() throws Exception {
        String processDefinitionKey = "baoxiaoFlow";
        ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceByKey(processDefinitionKey);
        System.out.println("processInstance.getId()===" + processInstance.getId());
        System.out.println("processInstance.getProcessDefinitionId()===" + processInstance.getProcessDefinitionId());
    }


    //3、根据流程实例，查询任务列表  ,说明一个流程定义对应多个流程实例，一个流程实例对应多个任务列表
    @Test
    public void getProcessTask() throws Exception {
        String processInstanceId = "5001";
        //1
        String assignee = "tom";
        //2
        //String assignee = "jack";
        //3
        //String assignee = "smith";
        //任务列表
        TaskQuery taskQuery = processEngine.getTaskService().createTaskQuery();
        //查询tom的任务列表
        taskQuery.taskAssignee(assignee);
        taskQuery.orderByTaskCreateTime().desc();
        List<Task> tasks = taskQuery.list();
        for (Task task : tasks) {
            System.out.println(task.getId() + ":" + task.getName());
        }
    }

    //4、办理任务,办理完成后，第三步就找不到tom的这个任务了，跑到下个jack的任务中了,5与6是相互重复的
    @Test
    public void dealProcessTask() throws Exception {
        //String taskId = "12506"; //提交
        String taskId = "37509";  //项目经理审批
        processEngine.getTaskService().complete(taskId);
    }

    //5.1、查询历史记录ACT_HI_PROCINST
    @Test
    public void queryProcessTaskHistory() throws Exception {
        HistoricProcessInstanceQuery query = processEngine.getHistoryService().createHistoricProcessInstanceQuery();
        query.orderByProcessDefinitionId().desc();
        query.orderByProcessInstanceEndTime().asc();
        List<HistoricProcessInstance> list = query.list();
        for (HistoricProcessInstance hpi : list){
            System.out.println(hpi.getId() + ":" + hpi.getName());
        }

    }

    //5.2、查询历史活动记录ACT_HI_ACTINST
    @Test
    public void queryProcessTaskActHistory() throws Exception {
        HistoricActivityInstanceQuery query = processEngine.getHistoryService().createHistoricActivityInstanceQuery();
        List<HistoricActivityInstance> list = query.list();
        for (HistoricActivityInstance hpi : list){
            System.out.println(hpi.getId() + ":" + hpi.getActivityName() + ":" + hpi.getActivityType());
        }

    }

    //5.3、查询历史任务记录ACT_HI_TASKINST
    @Test
    public void queryProcessTaskTaskHistory() throws Exception {
        HistoricTaskInstanceQuery query = processEngine.getHistoryService().createHistoricTaskInstanceQuery();
        List< HistoricTaskInstance> list = query.list();
        for ( HistoricTaskInstance hpi : list){
            System.out.println(hpi.getId() + ":" + hpi.getAssignee() + ":" + hpi.getName());
        }

    }
