           <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository" />

           <context:include-filter type="annotation" expression="org.springframework.stereotype.Service" />

           <context:include-filter type="annotation" expression="org.springframework.stereotype.Component" />

               

     </context:component-scan>

 

 

</beans>

 

 

spring-servlet.xml 에서 com.bitacademy.emaillist.controller 의 스캔하게 설정했고

applicationContext.xml 에서는 com.bitacademy.emaillist.repository 의 스캔을 설정했는데

 

굳이 두개의 xml파일로 나누어서 스캔 설정을 한 이유가 있을까요?

spring-servlet.xml 에 controller, repository 스캔을 한번에 하면 안되나요?

 

=> controller 스캔과 repository 스캔 설정을 따로 두는 것을 spring에서 권고하고 있다.

 

spring-servlet.xml 파일에 비지니스 객체를 먼저 로딩시키고,

DB요청이 들어왔을때 repository.xml 파일의 객첼르 로딩시키는게 효율적이다.
