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>
