Java新特性：异步编排CompletableFuture

CompletableFuture由Java 8提供，是实现异步化的工具类，上手难度较低，且功能强大，支持通过函数式编程的方式对各类操作进行组合编排。 CompletableFuture实现了CompletionStage接口和Future接口，前者是对后者的一个扩展，增加了异步回调、流式处理、多个...

异步传统单线程环境下，调用函数是同步的，必须等待程序返回结果后，才可进行其他处理。因此为了提高系统整体的并发性能，引入了异步执行~jdk中已经内置future模式的实现。Future是Java5添加的类，用来描述一个异步计算的结果。可以用isDone方法来检查计算是否完成，或者使用get阻塞住调用线...
