包扫描配置

spring配置文件

context:exclude-filter排除Controller上的注解，即@Controller的bean不被扫描

 <context:component-scan base-package="org.xuan.springmvc">
        <context:exclude-filter type="annotation"
                                expression="org.springframework.stereotype.Controller"/>
  </context:component-scan>

springmvc配置文件

use-default-filters="false"禁用默认包扫描，默认为true的话会扫描父容器上的service和dao导致大量重复bean

context:include-filter只扫描Controller上的注解

 <context:component-scan base-package="org.xuan.springmvc.controller"
                            use-default-filters="false">
        <context:include-filter type="annotation"
                                expression="org.springframework.stereotype.Controller"/>
  </context:component-scan>
