如何停止使用@Scheduled批注启动的计划任务？

选项1：使用后处理器

为应停止调度的bean
提供

ScheduledAnnotationBeanPostProcessor

postProcessBeforeDestruction(Objectbean, String beanName)

选项2：维护目标豆与其未来的映射

private final Map<Object, ScheduledFuture<?>> scheduledTasks =        new IdentityHashMap<>();@Scheduled(fixedRate = 2000)public void fixedRateJob() {    System.out.println("Something to be done every 2 secs");}@Beanpublic TaskScheduler poolScheduler() {    return new CustomTaskScheduler();}class CustomTaskScheduler extends ThreadPoolTaskScheduler {    @Override    public ScheduledFuture<?> scheduleAtFixedRate(Runnable task, long period) {        ScheduledFuture<?> future = super.scheduleAtFixedRate(task, period);        ScheduledMethodRunnable runnable = (ScheduledMethodRunnable) task;        scheduledTasks.put(runnable.getTarget(), future);        return future;    }    @Override    public ScheduledFuture<?> scheduleAtFixedRate(Runnable task, Date startTime, long period) {        ScheduledFuture<?> future = super.scheduleAtFixedRate(task, startTime, period);        ScheduledMethodRunnable runnable = (ScheduledMethodRunnable) task;        scheduledTasks.put(runnable.getTarget(), future);        return future;    }}

当必须停止对bean的调度时，可以查找该映射以获取对应的映射

Future
