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
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，http://search.maven.org/ 只要输入包名即可查找引来关系
pom.xml(包依赖)

27 User user = new User();
28 user.setNickname("你好");
29 user.setState(2);
30 System.out.println(userService.insertUser(user));

将该项目部署到本地tomcat6中
右击该项目选择Run as，选择Run on Server
选择自己建立的tomcat6运行如图：
控制台打印出日志如图（启动成功）：
在浏览器中输入：http://localhost:8080/springmvc/index.do 进行测试
效果如图（返回成功）：
