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

1. 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");
   }
   
   

2. 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());
   }
   
   

3. 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());
   }
   
   

4. 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

1. 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);
   }
   
   

2. 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);
   }
   
   

3. 可以看到流程之间调用时，使用taskService.complete(流程id, Map类型变量)完成传参，其中Map类型变量中的key为bpmn中子流程节点CallActivityTask设置好的属性名
