Question:-
What is DispatcherServlet and ContextLoaderListener?
 
Answer:-
<web-app>
  <display-name>Archetype Created Web Application</display-name>
   
  <servlet>
        <servlet-name>spring</servlet-name>
            <servlet-class>
                org.springframework.web.servlet.DispatcherServlet
            </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
 
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
     
</web-app>

DispatcherServlet loads its configuration file using <servlet_name>-servlet.xml. E.g. with above web.xml file, DispatcherServlet will try to find spring-servlet.xml file in classpath.

ContextLoaderListener reads the spring configuration file (with value given against “contextConfigLocation” in web.xml), parse it and loads the beans defined in that config file

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
     
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </init-param>
     
    <load-on-startup>1</load-on-startup>
</servlet>
