Answer

Your mistake is here:

<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet-servlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

In your servlet mapping, you need to refer to a servlet that has been defined in your web.xml and here only dispatcherServlet has been defined so simply rename dispatcherServlet-servlet into dispatcherServlet in your servlet mapping as next:

<servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
