    <!--示例1
    use-default-filters="false" 表示现在不使用默认filter,自己配置filter
    context:include-filter，设置扫描哪些内容
    
    
    -->
    <context:component-scan base-package="com.atguigu" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--示例2
        下面配置扫描包所有内容
        context:exclude-filter:设置哪些内容不进行扫描
    
    -->
    <context:component-scan base-package="com.atguigu" >
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
