子流程

bpmn设置

定义流程，id为LeaveProcess2

定义流程，id为LeaveProcess1，在其中使用子流程节点CallActivityTask调用其它流程，它的属性Called Element值为其它流程Id

代码

部署两个流程，并启动LeaveProcess1

@Test
public void delopyAllBpmn() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    processEngine.getRepositoryService()
            .createDeployment()
            .addClasspathResource("bpmn/LeaveProcess2.bpmn")
            .name("请假流程")
            .deploy();

    processEngine.getRepositoryService()
            .createDeployment()
            .addClasspathResource("bpmn/LeaveProcess1.bpmn")
            .name("请假流程2")
            .deploy();
}


@Test
public void startProcessInstance() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    processEngine.getRuntimeService()
            .startProcessInstanceByKey("LeaveProcess1");
}

此时LeaveProcess1处于第一个节点，让这个节点的责任人调用complete完成任务，推进节点

@Test
public void testApplyTask() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    Task task = taskService
            .createTaskQuery()
            .singleResult();
    taskService.setAssignee(task.getId(), "zhangsan");
    taskService.complete(task.getId());
}

此时就会进入子节点，由此自动基于LeaveProcess2生成一个流程实例，该流程实例中，经理进行审批，审批完成后调用complete完成任务，推进节点

@Test
public void testPMTask() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    Task task = taskService
            .createTaskQuery()
            .singleResult();
    taskService.setAssignee(task.getId(), "pm");
    taskService.complete(task.getId());
}

此时就会回到LeaveProcess1.bpmn中的人事审批，人事审批完成后，流程结束

public void testHRTask() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    Task task = taskService
            .createTaskQuery()
            .singleResult();
    taskService.setAssignee(task.getId(), "hr");
    taskService.complete(task.getId());
}

流程之间的传参

LeaveProcess1流程中，负责人zhangsan发起申请，并完成任务，同时设置pmAuditor变量最终赋值给pm变量，最后调用子流程，进入到经理审批

@Test
public void testApplyTask() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    Task task = taskService
            .createTaskQuery()
            .singleResult();
    taskService.setAssignee(task.getId(), "zhangsan");

    Map<String, Object> variables = new HashMap<>();
    variables.put("pmAuditor", "wangjingli");
    taskService.complete(task.getId(), variables);
}

经理直接审批结束，设置变量hrAuditor赋值给hr，结束LeaveProcess2，回到LeaveProcess1，进入人事审批

@Test
public void testPMTask() {
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    Task task = taskService
            .createTaskQuery()
            .singleResult();
    Map<String, Object> variables = new HashMap<>();
    variables.put("hrAuditor", "zhaoHR");
    taskService.complete(task.getId(), variables);
}
