contexConficLocation is using in web.xml file. This purpose is override the acctual or default XML file in user wish. It is comeing under the <contex-param> tag, for example

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/spring-config.xml,WEB-INF/spring-servlet.xml</param-value>

InternalResourceViewResolver using inside servlet.xml file it is comeing under the viewResolver bean.

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="WEB-INF/view/"></property>
