首先通过 MoreExecutors 类的静态方法 listeningDecorator 方法初始化一个 ListeningExecutorService 的方法,然后使用此实例的 submit 方法即可初始化 ListenableFuture 对象。 ListenableFuture 要做的工作,在Callable接口的实现类中定义,这里只是休眠了1秒钟然后返回一个数字1,有了ListenableFuture实例,可以执行此Future并执行Fu...

最近刚好使用CompeletableFuture优化了项目中的代码,所以跟大家一起学习CompletableFuture。 公众号:捡田螺的小男孩 一个例子回顾 Future 因为CompletableFuture实现了 Future 接口,我们先来回顾Future吧。 Future是Java5新加的一个接口,它提供了一种异步并行计算的功能。如果主线程需要执行一个很耗时的计算任务,我们就可以...
• schedule(Runnable command,long delay,TimeUnit unit),带延迟时间的调度,只执行一次,调度之后可通过Future.get()阻塞直至任务执行完毕。 • schedule(Callablecallable,long delay,TimeUnit unit),带延迟时间的调度,只执行一次,调度之后可通过Future.get()阻塞直至任务执行完毕,并且可以获取执行结果。
own instance of PhantomReference while activeQueue can be used with any type of Reference (just choose your own and make it implement Runnable). For many usecases the activeQueue approach is more efficient. Often one needs WeakReference or SoftReference to the object and also the cleanup code ...
