说明：  本系统采用struts+spring+hibernate架构，重在讲述三者结合在一起的应用开发，所有源程序都有详细的注释，供入门者学生参考，未经作者允许不得用于商业用途，只能用于教学或个人学习。 程序只是整个系统中的一个模块，用于和各位程序爱好者交流之用。 使用方法： (1)在oracle数据库中运行数据库脚本文件cnc.sql. (2)用eclipse(或其它开发工具)直接导入工程. (3)将spring配置文件applicationContext.xml中数据库连接地址改为您自已的地址。 (4)部署到tomcat服务器中即可运行(jdk1.5以上). 用户名和密码均为：admin(The system uses struts+ Spring+ Hibernate framework, focusing on the three combined application development, all have detailed source notes, for beginners to students without author permit shall not be used for commercial purposes, can only be used in teaching or individual learning. Procedures for the entire system is only one of the modules, and all procedures for lovers to exchange purposes. Usage: (1) in the oracle database to run the database script file cnc.sql. (2) to use eclipse (or other development tools) directly into the project. (3) spring configuration file applicationContext.xml in the database connection address changed your own address. (4) deployed to the tomcat server to run (jdk1.5 and above). A user name and password are: admin)
