添加相关的service,dao,controller等文件夹 如：src/main/java路径下添加自己定义的包名: com.myjava.controller com.myjava.dao —接口 com.myjava.domain —实体类 com.myjava.service —服务接口 com.myjava.service.impl —服务实现类
在src/main/resources路径下添加: applicationContext.xml —spring 监听器的配置文件 springmvc.xml —springMVC控制器的配置文件 （1）applicationContext.xml中包含了Mybatis的相关配置：
<?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" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--开启注解扫描，只处理service和dao,而controller不需要spring框架去处理--> <context:component-scan base-package="com.myjava"> <!--配置不需要注解扫描的--> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"></context:exclude-filter> </context:component-scan> <!--spring 整合MyBatis框架--> <!--配置连接池--> <bean id="comboPooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="com.mysql.jdbc.Driver"/> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test"/> <property name="user" value="root"/> <property name="password" value="root"/> </bean> <!--配置SqlSessionFactory工厂--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="comboPooledDataSource"></property> </bean> <!--配置接口所在包--> <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.myjava.dao"></property> </bean> <!--配置spring框架声明式事务管理--> <!--配置事务管理器--> <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="comboPooledDataSource"></property> </bean> <!--配置事务通知--> <tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager"> <tx:attributes> <tx:method name="find*" read-only="true"/> <tx:method name="*" isolation="DEFAULT"></tx:method> </tx:attributes> </tx:advice> <!--配置AOP增强--> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.myjava.service.impl.*ServiceImpl.*(..))"></aop:advisor> </aop:config> </beans>（2）springmvc.xml 内容如下：
