SpringMVC+Spring+Mybatis 框架搭建
整个Demo的视图结构：

首先，我是使用MyEclipse工具做的这个例子，整合了Sping 3 、Spring MVC 3 、MyBatis框架，演示数据库采用MySQL数据库。例子中主要操作包括对数据的添加（C）、查找（R）、更新（U）、删除（D）。我在这里采用的数据库连接池是来自阿里巴巴的Druid，至于Druid的强大之处，我在这里就不做过多的解释了，有兴趣的朋友们可以去网上谷歌或者百度一下哦！好了下面我就贴上这次这个演示例子的关键代码：
example目录下是一个基本案例：

通过Web.xml加载SpringMVC+Spring+Mybatis的配置文件
首先是Spring.xml ,spring-mybatis.xml俩文件
Spring.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
<context:component-scan base-package="com.talent.example.controller" />
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" />
</beans>
以上就是几个关键位置的代码，我全部贴出来了。至于配置文件什么的，由于时间原因没有贴出。如果大家要是感兴趣的话，可以下载我的这个演示项目包，里面的东西都齐全着，导入到MyEclipse上面直接部署到服务器上面就可以运行。数据库就是里面的那个.sql文件。建个库然后将数据导入就是。哦，对了。导完数据后，记得别忘了到config.properties里面去把数据库的连接信息换成你自己哦！
