基于JSPjava+servlet+mvc宠物销售系统的设计与实现javabean
基于JSPjava+servlet+mvc宠物销售系统的设计与实现javabeanmysql数据源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：
Eclipse ,MySQL 5.1,JDK1.7,Tomcat 7
涉及技术点：
MVC模式、JavaWeb、JDBC、HTML、CSS、JQUERY、Bootstrap、json、PageModel分页、等。

系统没用任何框架，前台纯JSP实现，后台servlet映射，适合刚学习J2EE的新手，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1.7. 编程软件Eclispe J2EE版本。是典型MVC架构，并且前后台分离，
具体功能这里不再赘述，请下方看系统详细演示图，如果大家有什么疑问或者什么不懂得可以在下方给我留言，也可以私信我和我一起交流沟通，互相学习进步！代码you’chang
