由于项目基于Maven项目进行搭建的，如果使用动态web项目搭建的话，则需要自己下载相关jar包
1、首先在POM.xml中配置相关的信息，获取与项目相关的jar包（这是用于下载相关jar包的配置文件）
spring-webmvc.jar，spring-jdbc.jar，spring-tx.jar(这是spring事务管理器)，c3p0.jar(或者使用dbcp.jar也可以)
mysql.jar，mybatis.jar，mybatis-spring.jar等等。

id="WebApp_ID" version="3.1">
</web-app><groupId>commons-pool</groupId> <artifactId>commons-pool</artifactId> <version>1.6</version></dependency> </dependencies>
2、配置web.xml，你可以根据自己的xml的版本进行自己更改，这个配置文件用于配置springmvc的相关信息
可以更改为以下版本：
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
</web-app>
配置spring-mvc.xml和spring-context.xml的位置，以及配置springmvc拦截器，字符编码器
<!-- 请求和应答字符编码过滤器-->
<filter>
<filter-name>encoding-filter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>encoding-filter</filter-name>
<servlet-name>spring-mvc</servlet-name>
</filter-mapping>
<!-- springmvc的前端控制器 -->
<listener>
<description>启动spring容器</description>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/spring-context.xml</param-value>
</context-param>
<servlet>
<servlet-name>spring-mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-mvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>3、在spring-mvc.xml配置相关信息（需要在eclipse配置好spring）
<!-- springmvc驱动 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!-- 扫描控制器 -->
<context:component-scan base-package="com.haki.vip.web.handler"></context:component-scan>
4、在spring-context.xml配置数据源以及mapper相关映射
<!-- 扫描业务层组件 -->
<context:component-scan base-package="com.haki.vip.function"></context:component-scan>
<!-- c3p0数据源 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3306/vip"></property>
<property name="user" value="root"></property>
<property name="password" value="root"></property>
<property name="minPoolSize" value="1"></property>
<property name="maxPoolSize" value="5"></property>
<property name="initialPoolSize" value="1"></property>
<property name="acquireIncrement" value="1"></property>
</bean>
<!-- 配置一个事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 使用注解控制事务 -->
<tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<property name="mapperLocations">
<list>
<value>classpath:mapper/*.xml</value>
</list>
</property>
</bean>
<!-- 扫描生成所有的dao层对象 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.haki.vip.dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" ></property>
</bean>5、在mybatis.xml配置信息
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<setting name="cacheEnabled" value="true"></setting>
<setting name="defaultStatementTimeout" value="3000"></setting>
<setting name="mapUnderscoreToCamelCase" value="true"></setting>
<setting name="proxyFactory" value="CGLIB"></setting>
<setting name="lazyLoadingEnabled" value="true"></setting>
</settings>
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<property name="dialect" value="mysql"></property>
<property name="offsetAsPageNum" value="true"></property>
<property name="rowBoundsWithCount" value="true"></property>
<property name="pageSizeZero" value="true"></property>
</plugin>
</plugins>
</configuration>6、配置mapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="相对应方法接口">
<select id="select" resultType="相对应的实体类" >
select * from user where id=#{id}
</select>
</mapper>7、目录结构如下
总结：大概就是这样了吧
