請問我在spring中new了一個Timer，為什么沒有觸發呢？

@Override
public?void?handleRemind(SendWxMessage?sendWxMessage,VisitPlan?visitPlan){
????Timer?timer?=?new?Timer();
????RemindTimerTask?remindTimerTask?=?new?RemindTimerTask(sendWxMessage,visitPlan);
????timer.schedule(remindTimerTask,visitPlan.getRemind());
}

public?RemindTimerTask(SendWxMessage?sendWxMessage,VisitPlan?visitPlan){
????this.sendWxMessage?=?sendWxMessage;
????this.visitPlan?=?visitPlan;
}

????@Override
????public?void?run()?{
????????System.out.println("***********************");
????????sendWxMessage.handleSendPlanMessage(visitPlan);
????????System.out.println("111111111111111111111");
????????System.out.println("***********************");
????}
