流程实例系列（RuntimeService）

启动流程方式

直接启动

ProcessInstance processInstance =
    runtimeService.startProcessInstanceByKey(processDefinitionKey);

任意节点启动

    /**
     * 任意节点
     */
    @Test
    public void createProcessInstanceByKey(){
        String processDefinitionKey = "Process_0ihs6z7";
        String activityId = "Task_1ojlhmg";
        ProcessInstantiationBuilder instantiationBuilder = runtimeService.createProcessInstanceByKey(processDefinitionKey);
        instantiationBuilder.businessKey("gjf")
//                .startBeforeActivity(activityId)  //节点之前
//                .startBeforeActivity(activityId)  //节点之后
                .startTransition("SequenceFlow_1ojnaaf")  //线
                .execute();
    }

状态

历史记录

• act_ru_execition : 正在执行的信息
• act_hi_procinst : 已经执行完成的历史流程实例信息
• act_hi_actinst : 存放历史所有完成的活动
• act_ru_task : 正在执行的任务信息
• act_hi_taskinst : 已经执行完成的历史任务信息

  历史活动信息查询

  

  历史任务查询

  

发起人设置

    @Test
    public void start(){
        String authenticatedUserId = "gjf";
        identityService.setAuthenticatedUserId(authenticatedUserId);
        runtimeService.startProcessInstanceById("Process_0ihs6z7:1:3");
    }

删除实例

删除单个

删除多个

    /**
     * 删除
     * delete from ACT_RU_TASK where ID_ = ? and REV_ = ?
     * delete from ACT_RU_EXECUTION where ID_ = ? and REV_ = ?
     * UPDATE ACT_HI_ACTINST SET EXECUTION_ID_ = ?, PROC_DEF_KEY_ = ?, PROC_DEF_ID_ = ?, ACT_ID_ = ?, ACT_NAME_ = ?, ACT_TYPE_ = ?, PARENT_ACT_INST_ID_ = ? , END_TIME_ = ? , DURATION_ = ? , ACT_INST_STATE_ = ? WHERE ID_ = ?

     */
    @Test
    public void deleteProcessInstance(){
        runtimeService.deleteProcessInstance("301","删除测试");
    }
    @Test
    public void deleteProcessInstance1(){
        List<String> processInstanceIds = Arrays.asList("401", "501");
        runtimeService.deleteProcessInstances(processInstanceIds,"批量删除",true,true);
    }

流程实例获取运行的活动节点

    /**
     * select * from ACT_RU_EXECUTION where PROC_INST_ID_ = ?
     */
    @Test
    public void getActiveActivityIds() {
        String executionId = "101";
        List<String> activeActivityIds = runtimeService.getActiveActivityIds(executionId);
        activeActivityIds.stream().forEach(System.out::println);
    }
    @Test
    public void getActivityInstance() {
        String processInstanceId = "101";
        ActivityInstance activityInstance = runtimeService.getActivityInstance(processInstanceId);
        System.out.println(activityInstance);
    }

流程定义的挂起和激活操作

指定流程定义的挂起

@Test
    public void suspendProcessDefinitionById(){
        //挂起
//        repositoryService.suspendProcessDefinitionById("Process_0ihs6z7:3:603");
        //测试 发起流程
        //org.camunda.bpm.engine.SuspendedEntityInteractionException:
        // ENGINE-03043 Process Definition with id 'Process_0ihs6z7:3:603' is suspended.
//        runtimeService.startProcessInstanceById("Process_0ihs6z7:3:603");
        //激活
        repositoryService.updateProcessDefinitionSuspensionState()
                .byProcessDefinitionId("Process_0ihs6z7:3:603")
                .activate();
    }
