基于XML实现Spring整合mybatis

    <!--加载配置文件-->
    <context:property-placeholder location="classpath:*.properties"></context:property-placeholder>
    <!--配置数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}"></property>
        <property name="url" value="${jdbc.url}"></property>
        <property name="username" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>
    <!--由于dao层的实现类是动态代理生成的，这里直接ref-->
    <bean id="accountService" class="com.itheima.service.impl.AccountServiceImpl">
        <property name="accountDao" ref="accountDao" />
    </bean>
    <!--配置SqlSessionFactoryBean，并且配置属性：mybatis起别名typeAliases-->
    <bean  class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="typeAliasesPackage" value="com.itheima.domain"></property>
    </bean>
    <!--mybatis扫描mapper.xml-->
    <bean  class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.itheima.dao"></property>
    </bean>
