静态
    <mvc:default-servlet-handler/>
    <!--其他就走其他咯-->
    <mvc:annotation-driven/>
扫描位置        加上这句 use-default-filters="false"  就只包含我要包含的了  那还不如我指定下一级

    <context:component-scan base-package="com.itheima.controller   >
    </context:component-scan>
    <!--加载配置文件-->
    <context:property-placeholder location="classpath:*.properties"/>
    <!--扫描包-->
    <context:component-scan base-package="com.itheima">
排除mvc的bean
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--数据源-->

    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
数据库相关

    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="typeAliasesPackage" value="com.itheima.domain"/>
    </bean>
dao层的东西
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.itheima.dao"/>
    </bean>

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:annotation-driven/>
    <!--扫描加载所有的控制类类-->

    <!--<mvc:resources mapping="/img/**" location="/img/"/>-->

   


    <!--
        如果是自己写的bean，用注解
        如果是第三方的bean，用配置文件
    -->

</beans>
