The methods without the Async postfix run the next execution stage using a calling thread. In contrast, the Async method without the Executor argument runs a step using the common fork/join pool implementation of Executor that is accessed with the ForkJoinPool.commonPool() method. Finally, the ...
CompleteFuture is a concurrent programming framework introduced in Java 8 to simplify asynchronous programming and the processing of concurrent tasks. It provides a set of methods that can be used to manage the execution of asynchronous tasks, processing of results, task combinations, and exception ...

异步加载数据时候,可以对future设置超时时间,实现更加灵活的控制。 二:异步编程CompleteFuture实战 2.1 Future获取任务结果 使用Future获得异步执行结果时,要么调用阻塞方法get(),要么轮询看isDone()是否为true,这两种方法主线程也会被迫等待。 从Java 8开始引入了CompletableFuture,它针对Future做了改进,可以传入回调对象,...
