编写spring的配置文件：

 

 

<?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">

    <!--开启注解的扫描,希望处理service和dao，controller不需要spring框架去处理-->
    <context:component-scan base-package="cn.itcast">
        <!--配置那些注解不扫描,type是类型（为注解），expression是注解的全路径-->
        <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="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm"/>
        <property name="user" value="root"/>
        <property name="password" value="123456"/>
    </bean>
    <!--配置SqlSessionFactory工厂-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--通过dataSource连接池构建工厂-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--配置AccountDao接口所在包-->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--扫描基本的包-->
        <property name="basePackage" value="cn.itcast.dao"/>
    </bean>
</beans>

有了这就可以删除mybatis的配置文件：

 

 把account交给ioc去管

 

 在service中注入account接口
