1.包含源程序，数据库脚本。代码和数据库脚本都有详细注释。
2.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
代码已经上传github，下载地址https://github.com/21503882/net-flower
开发环境：
Eclipse ,MYSQL,JDK1.8,Tomcat 7
涉及技术点：
MVC模式、SpringBoot、HTML、shiro、log4j、druid、springloaded、ueditor、pagehelper、pinyin4j、mail、ehcache、quartz、JavaScript、CSS、JQUERY、Ajax等
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
