Interceptor 설정

1. servlet-context.xml

   <!-- common interceptor -->
	<interceptors>
       <interceptor>
           <mapping path="/**"/>
           <beans:bean id="commonInterceptor" class="secretary.common.filter.CommonInterceptor"/>
       </interceptor>
    </interceptors>
	<!-- inteceptor end -->

2. Interceptor 개발
