Web应用中并发控制的实现

Web应用已由原来的网站、电子商务发展成商业应用系统的一种架构-B/S架构,它已成为一个世界性的研究热点。但由于Internet网络协议固有的局限性以及Web应用中频繁的用户交互增加了在Internet上实现长事务的困难,从而,Web应用中的并发控制始终没能得到很好的解决。本文从Hibernate的乐观锁和悲观锁的实现原理出发,给出了实现悲观锁的基本思路和实现时的注意事项,在其它架构中得以推广和应用。

Concurrency realization in web application

Web application developed into an architecture-B/S architecture from web sites, e-commerce, and has become a worldwide research hot spot. The basic difficulties in the implementation of long transaction processing because of frequent and long-time interaction as occurred in most Web applications and some inherent constraints from the Internet's networking protocols. As a result, concurrency in web application still fails to be resolved perfectly. In this paper, we provide the basic solution of Pessimistic Locking and implementation constrains based on the Pessimistic Locking and Optimistic Locking in Hibernate framework.
