【實用小技巧】spring與springmvc自動掃描包重復的問題解決

spring對應配置文件為：

	<!-- 配置自動掃描的包,此時要排除Controller -->
	<context:component-scan base-package="com.lw">
		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>

springmvc對應的配置文件為：

	<!-- user-default-filters 與 include-filter搭配使用 實現僅僅掃描Controller注解 -->
	<context:component-scan base-package="com.lw" use-default-filters="false">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
	</context:component-scan>

注：屬性user-default-filters官方介紹：

Attribute : use-default-filters
Indicates whether automatic detection of classes annotated with @Component, @Repository, 
 @Service, or @Controller should be enabled. Default is "true".
