you have lots of xml file creating lots of confusion.first configure simple mvc add security , filter .so simple mvc web.xml looks below
<context-param> <param-name>contextconfiglocation</param-name> <param-value>web-inf/applicationcontext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> applicationcontext.xml
<context:component-scan base-package="com.projectshaun" /> <mvc:annotation-driven /> dispatcher-servlet.xml
<bean class="org.springframework.web.servlet.mvc.support.controllerclassnamehandlermapping"/> <bean id="viewresolver" class="org.springframework.web.servlet.view.internalresourceviewresolver" p:prefix="/web-inf/jsp/" p:suffix=".jsp" />
