**目录**

一，运行效果

二，新建dynamic web project

三，详细代码

web.xml

springmvc.xml

applicationContext\_mapper.xml

applicationContext\_service.xml

applicationContext\_transaction.xml

db.properties

ItemInfo.java

ItemController.java

ItemMapper.java

ItemMapper.xml

ItemService.java

ItemServicelmpl.java

item\_list.jsp

四，MySQL数据库文件

五，运行

六，完整项目下载

--------------------

这里需要maven的基础：[https://blog.csdn.net/qq\_40323256/article/details/90168191][https_blog.csdn.net_qq_40323256_article_details_90168191]

ssm的基础：[https://blog.csdn.net/qq\_40323256/article/details/89791744][https_blog.csdn.net_qq_40323256_article_details_89791744]

bootstrap的基础：[https://blog.csdn.net/qq\_40323256/article/details/91490905][https_blog.csdn.net_qq_40323256_article_details_91490905]

MySQL的基础：[https://blog.csdn.net/qq\_40323256/article/details/82905734][https_blog.csdn.net_qq_40323256_article_details_82905734]

注意：此项目和***[这个项目][Link 1]***都能实现同样的功能，不同点就是这个项目并没有使用maven，所有的jar包都是自己导入的。这个项目是dynamic web project，那个项目是maven project

# 一，运行效果 #

先来看一下最终运行效果

# ![20190615205858335.gif][]   二，新建dynamic web project #

先看下结构

注意：jar包记得build path
