SpringBoot整合Activiti7——取消结束/取消边界事件（十四）

取消结束/取消边界事件

只能在事务子流程中使用。
当到达取消结束事件时，会抛出取消事件，且必须由取消边界事件（cancel boundary event）捕获。取消边界事件将取消事务，并触发补偿（compensation）。

<!-- 取消结束事件 -->
<endEvent id="sid-ac48382a-e4e6-439d-8ff1-1960bc56391f" name="取消结束事件">
  <cancelEventDefinition/>
</endEvent>

<!-- 取消边界事件 当事务取消时触发 -->
<boundaryEvent id="sid-40c1a6b6-80ad-4112-b72a-294b16842a9c" name="取消边界事件" attachedToRef="sid-32b9116c-5a1d-481f-8d76-fc9fea4c0dbf" cancelActivity="true">

测试流程

@Test
public void deployAndStartProcessAndCompleteTask() {
    // 部署流程
    Deployment deploy = repositoryService.createDeployment()
            .addClasspathResource("processes/cancel.bpmn20.xml")
            .deploy();
    System.out.println("deploy = " + deploy);

    // 启动流程
    String processDefinitionKey = "cancel";
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey, processDefinitionKey + ":100001");
    System.out.println("processInstance = " + processInstance);

    // 完成保存任务
    Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();

    Map<String, Object> hashMap = new HashMap<>();
    hashMap.put("cancel", true); // true取消结束
    taskService.complete(task.getId(), hashMap);
}

流程执行步骤

// 1.部署启动流程并完成保存任务
// 2.是否取消结束=true
// 3.触发取消结束事件
// 4.触发取消边界事件
// 5.触发补偿自动任务、触发取消自动任务
// 6.结束流程
