bean config 설정 분리

applicationContext에 Data가 늘어날수록 파일이 무거워지기 때문에 Bean Config 설정을 분리한다.

Bean들을 한 곳에 정의하고 Listener를 통해 모두 Loading한다.

web.xml에서 ContextLoaderListener를 추가한다.

<!-- needed for ContextLoaderListener -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/spring/*Context.xml</param-value> <!-- /WEB-INF/spring/아래 있는 Context.xml파일은 다 가져온다. -->

</context-param>

<!-- Bootstraps the root web application context before servlet initialization -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<param-value>/WEB-INF/spring/*Context.xml</param-value> <!-- /WEB-INF/spring/아래 있는 Context.xml파일은 다 가져온다. -->

이미 Load된 Bean Container에 적재 된 Bean은 제외한다.

applicationContext.xml에서는 URL관련 설정을 작성한다. ( HandlerMapping, HandlerAdapter, Controller, ViewResolver 등 )

<?xml version="1.0" encoding="UTF-8"?>

</bean>

</beans>

rootContext.xml 에서는 DataBase 연동 설정을 작성한다. - DataSource, Transaction 등

<?xml version="1.0" encoding="UTF-8"?>

    <bean id="jdbc.Template"

    </bean>

</beans>

* Controller가 늘어날수록 applicationContext.xml파일이 무거워지기 때문에

Controller.xml을 생성해서 사용할Controller.xml을 만들고 resource를 import시킨다.

<Package>Context.xml에서는 주로 Package별 Content를 작성한다. -> Service, Dao 등

boardContext.xml에 board에 사용할 Query문을 작성한다.

<?xml version="1.0" encoding="UTF-8"?>

                    INSERT INTO SPRING.BOARD (

마찬가지로 memberContext.xml bean파일을 만들어서 사용할 Query문을 작성한다.
