如何用Java回调和线程实现异步调用

Implementation of Asynchronous Invocation by Java Callback and Thread

异步调用是一种非阻塞式调用方式,用于在处理比较耗时的任务时保证程序性能不受到影响。实现异步调用的关键在于要解决三个技术问题,它们分别是程序阻塞问题、异步消息的传递问题和超时问题。本文介绍的开发方法和步骤采用并发线程、回调机制和计时器圆满地解决了异步调用的技术难题。

The asynchronous invocation is a non-blocking call, which is used to process the time- consuming task while keeping high program performance. Blocking, asynchronous messaging and timeout are the three key problems to implement asynchronous invocation and this article proposes the approach to solve these problems by Java.
