 流程图：

 

 

serviceTask处理：

@Component
public class SwTimeOutProcessorListener implements JavaDelegate {

    @Autowired
    private TimeOutManagerService timeOutManagerService;
    @Autowired
    private TaskService taskService;

    @Override
    public void execute(DelegateExecution execution) throws Exception {
        //获得事务id
        String businessKey = execution.getProcessBusinessKey();
        Task task = taskService.createTaskQuery().processInstanceId(execution.getProcessInstanceId()).singleResult();
        String assignee =task.getAssignee();

        System.out.println(assignee);

        //插入超时记录
        //timeOutManagerService.addTimeOut(Integer.valueOf(assignee), Integer.valueOf(businessKey));


    }

}

定时边间事件：cancelActivity 说明：

cancelActivity属性：true时，当timer触发时，当前的activity被中断（流程结束）;

                                false时，当timer触发时，不会被中断（流程原点，流程不会结束），

当执行循环定时器时，虽然cancelActivity=true，但是该acitivity还是会持续生成

cancelActivity默认为true中断事件(结束流程)

cancelActivity为false非中断事件(还停留在原地，流程不结束)

中断和非中断的事件还是有区别的。默认是中断事件。

非中断事件的情况，不会中断原始环节，那个环节还停留在原地。 对应的，会创建一个新分支，并沿着事件的流向继续执行。
