资料 基于JAVA的数据库连接池的开发 摘要 在基于JDBC的数据库实际应用开发中,对数据库连接的管理是一个重点也是一个难点,频繁对数据库的连接与关闭操作、多客户对数据库的并发访问,一定程度上决定了WEB系统的响应以及应用性能。使用数据库连接池方式能对数据库的连接进行管理和维护,上层应用程序通过数据库连接池使用数据库资源能提升系统性能,充分利用系统资源。文章通过介绍、分析数据库连接池工作的基本原理,了解目前流行的WEB服务器在数据库连接池方面的使用现状后,总结一了些数据库连接池开发程序中容易忽略的问题。并在学习掌握了实现连接池的关键技术后给出了一个较为高效的连接池管理策略,在这种策略思想的指导下实际开发出一个数据库连接池模块,使得上层应用通过本连接池访问数据库资源变得相对高效和容易,从实际上论证了这种设计方案的可行性。 关键词:连接池;数据库;JDBC;并发访问 Research and realization of the Database Connection Pool Abstract In the practically application development of database based on JDBC, the management of database connection is a key point and also a difficulty. The response and performance of the WEB system are depended on frequently connecting, closing and multi-user accessing in a certain extent. Using the Database Connection Pool can provide management and maintenance for connections of the database. The upper applications may access the database recourse via the Database Connection Pool, in order to upgrade system performance and fully utilize the system recourse. This article summarizes some issues which are easily ignored in the application development of the Database Connection Pool by the way of introducing and analyzing the basal working principles of the Database Connection Pool ,comprehending the using actuality of the Database Connection Pool on the popular WEB servers. Besides, I established paratively highly effective policy of the Connection Pool management after having learned prehended key technique of implementing the Connectivity Pool, and actually had developed a Database Connection Pool module under the guidance of that policy, causing the access of system resource by the upper applications via current Connectivity Pool ing relatively highly effective and easy, demonstrated the feasibility of this design project in practice.
