此方法不依赖容器 框架，适用于小系统(主要JSP页面要少于100,因为是硬编码到JSP)，适用于要精确控制页面field的情况较多的系统。

(插句话：要分清权限控制与业务逻辑，业务逻辑就是情况由系统运行时的某些条件决定，如学生管理系统中，某一学生进入系统，只能看自己的记录，因为可看的记录是由学号来决定的，所以这是业务逻辑，而又如学生不能看老师的记录，这是有学生的身份来决定的，所以这是权限控制。)

好了，进入正题！

　　在使用数据库连接池的情况下，Tomcat可以支撑的并发量也十分有限。系统资源主要消耗在两方面：

　　1、数据库操作，频繁的从数据库返回结果;

　　2、Tomcat解析JAVA文件。
