基于jsp+servlet+ssm网上花店(花特别多界面丰富)

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
