整体包下载地址：springMVC+mybatis框架搭建首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。）1. 工程目录结构整理清楚在src/main/java文件夹中，新建包cn.springmvc.model(存放javabean), cn.springmvc.dao（存放spring与mybatis连接接口）, cn.springmvc.service（service接口）, cn.springmvc.service.impl（service接口的实现）， cn.springmvc.controller（存放控制层controller）在src/main/resource文件夹中，新建包conf（存放配置文件）， mapper（mybatis的mapper文件）在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）这样项目结构基本完成了回到顶部2. 引入依赖包打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）查找依赖结构有个不错的网站，/ 只要输入包名即可查找引来关系pom.xml(包依赖)?1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465666768697071727374757677787980818283848586878889909192939495969798991001011021031041051061071081091101111121131141151161171181191201211221231241251261271281291301311321331341351361371381391401411421431444.0.0eyas.springmvcspringmvcwar0.0.1-SNAPSHOTspringmvc
