方法之间可以相互调用，同理，流程定义之间也可以相关调用，达到流程定义复用的目的。

一：流程定义1

二：流程定义2

Called Element: 调用其它流程，值为其它流程Id。

三：启动和启动流程

@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");

四：发起申请

@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());

张三发起请假流程，然后并审核自己，进入下一个节点，直接进入了LeaveProcess2.bpmn文件中定义的第一个流程。

五：经理审批

@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());

经理审批完，又回到了LeaveProcess1.bpmn中的人事审批了。
