课题设计仅供参考学习使用，可以在此基础上进行扩展完善
开发环境：
代码已经上传github，下载地址：https://github.com/21503882/network-flower
Eclipse ,MYSQL,JDK1.8,Tomcat 7
涉及技术点：
MVC模式、SpringMvc、Mybatis、Spring、bootstrap、HTML、JavaScript、CSS、JQUERY、log4j、Ajax、maven等
系统采用Mybatis框架实现ORM对象关系映射，前台JSP实现，后台springMvc映射，使用Spring框架进行整合。适合学习J2EE的一段时间的熟手，代码思路清晰，注解详细，数据库用的是mysql5.1，服务器用的tomcat7，JDK版本1.8. 编程软件Eclispe J2EE版本。是典型MVC架构，并且前后台分离
