前言
前段时间在博客园上找了一个springmvc的例子，照着学了一下，算是对springmvc有了一个初步的了解，打一个基础，下面是链接。（我只看了博客，视频太耗时间了）
老师前几天让我练习一下用ajax做增删改查，只给了我一张数据库的表，什么都不多说。过程肯定是十分痛苦，因为技术方面只是略知一二，真正做的时候真的是无从下手，老师又什么都不告诉你，顾着自己的事，网上各种百度，找学长帮忙，但是毕竟学长也很忙，所以说学习真的还是要看自己。不过，花了整整四天的时间，终于还是做出来了，功夫不负有心人。虽然做的真的是相当的low，代码方面也还有很多不足的地方。
最终效果展示页面：
准备工作
打开myecipse2014，打开数据库服务，打开navicat，将表导入数据库......等等，我就不多说了。
