一、数据对象DataObject

DataObject可以⽤来定义⼀些流程的全局属性。

1. 绘制流程图，并配置数据对象（不需要选择任意节点）
   
   2. 编码与测试

/**
 * 部署流程
 */
@Test
void deploy() {
    Deployment deployment = repositoryService.createDeployment()
            .addClasspathResource("process/请假流程-dataObj.bpmn20.xml")
            .name("DataObj").deploy();
    System.out.println("deployment.getId() = " + deployment.getId());
    System.out.println("deployment.getName() = " + deployment.getName());
}

/**
 * 启动流程
 */
@Test
void startFlow() {
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(PROC_KEY);
    System.out.println("processInstance.getId() = " + processInstance.getId());
}

/**
 * 查询数据对象
 * Test2_DataObj    : key: creater,name: 流程创建人,value: Huathy
 */
@Test
void getDataObj() {
    ProcessDefinition pd = repositoryService.createProcessDefinitionQuery()
            .processDefinitionKey(PROC_KEY).latestVersion().singleResult();
    List<Execution> list = runtimeService.createExecutionQuery().processDefinitionId(pd.getId()).list();
    list.forEach(execution -> {
        DataObject obj = runtimeService.getDataObject(execution.getId(), "流程创建人");
        String msg = String.format("key: %s,name: %s,value: %s", obj.getDataObjectDefinitionKey(), obj.getName(), obj.getValue());
        logger.info(msg);
    });
}

查看ACT_RU_VARIABLE表，数据与ACT_RU_EXECUTION表中与EXECUTION_ID_相关联。

二、租户 Tenant

租户。多租户：单独的实例可以为多个组织服务。Flowable使用TenantID来区分流程归属于哪个租户。
部署与启动流程示例：部署的时候带上租户ID，后续的启动查询都要带上租户ID。

/**
 * 部署流程
 */
@Test
void deploy() {
    Deployment deployment = repositoryService.createDeployment()
            .addClasspathResource("process/请假流程-dataObj.bpmn20.xml")
            .name("DataObj").tenantId("A").deploy();
    System.out.println("deployment.getId() = " + deployment.getId());
    System.out.println("deployment.getName() = " + deployment.getName());
}

/**
 * 启动流程
 * processInstance.getId() = 0e33c8a0-a7b4-11ed-9f55-00155d067d63
 * org.flowable.common.engine.api.FlowableObjectNotFoundException: Process definition with key 'qjlc-dataObj' and tenantId 'B' was not found
 */
@Test
void startFlow() {
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKeyAndTenantId(PROC_KEY,"A");
    System.out.println("processInstance.getId() = " + processInstance.getId());
    ProcessInstance processInstance2 = runtimeService.startProcessInstanceByKeyAndTenantId(PROC_KEY,"B");
    System.out.println("processInstance2.getId() = " + processInstance2.getId());
}

三、接收任务 ReceiveTask

接收任务（ReceiveTask），是bpm2.0规范的一种任务，是一种等待任务，当该任务到达的时候，它不做任何逻辑，而是被动地等待用户Trigger。 当流程流转到接收任务，流程状态会保存到数据库（ACT_RU_EXECUTION表会维护该任务）。
使用场景：不明确的阻塞。例如一个复杂的计算需要等待很多条件，这些条件需要人工判断，则可以手动触发。

案例

1. 绘制流程图（信封✉图标）
   
2. 部署流程与启动流程（启动流程后，ACT_RU_TASK表并没有数据，而数据存放在ACT_RU_EXECUTION表）

/** 部署流程 */
@Test
void deploy() {
    Deployment deployment = repositoryService.createDeployment()
            .addClasspathResource("process/签收任务.bpmn20.xml")
            .name("ReceiveTask").deploy();
    logger.info("deployment.getId() = " + deployment.getId());
    logger.info("deployment.getName() = " + deployment.getName());
}
/** 启动流程 */
@Test
void startFlow() {
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(PROC_KEY);
    logger.info("processInstance.getId() = " + processInstance.getId());
}

3. 获取执行实例

@Test
void getExecution() {
    List<Execution> list = runtimeService.createExecutionQuery()
            .processDefinitionKey(PROC_KEY).list();
    list.forEach(execution -> {
        String msg = String.format("exeId: %s，exeName: %s, actID: %s", execution.getId(), execution.getName(),execution.getActivityId());
        logger.info(msg);
    });
}

4. 触发流程（由于trigger方法需要传入执行实例ID，所以可以根据ReceiveTask的节点名称，查询当前待触发的流程实例ID。ACT_RU_EXECUTION表的数据在trigger后会删除记录，历史记录保存到ACT_HI_ACTINST表）

@Test
void triggerAndQuery() {
    List<Execution> list = runtimeService.createExecutionQuery()
            .processDefinitionKey(PROC_KEY).activityId("cksj").list();
    list.forEach(execution -> {
        System.out.println("execution.getActivityId() = " + execution.getActivityId());
        runtimeService.trigger(execution.getId());
    });
}
