解析Java中的阻塞I/O与非阻塞I/O控制

The Analysis of the Blocking I/O Method and Non-Blocking I/O Method in Java

分析了新、旧I/O API工作原理及其可伸缩性方面的差异,阐述了如何用选择器通道技术让SocketChannel工作在非阻塞I/O模式下,以实现服务器与客户端无阻塞的、流畅的数据读写,使服务器能在较小的系统开销情况下更有效地、并发地为大量客户机提供服务,提升系统性能.

In this paper,the basic principle about the I/O API in Java and the difference of extendence between the Blocking I/O method and Non - Blocking method are expounded. Through Selector and channel technology, we can manage the Socketchannel working on the Non - Blocking model, which ensured the server to run efficiently and consume less resources, thus provided the possibility and technical assistance for the server to parallel service thousands of clients.
