What is Dispatcher Servlet in Spring?

Question

Answer 1

DispatcherServlet is Spring MVC's implementation of the front controller pattern.

See description in the Spring docs here.

Essentially, it's a servlet that takes the incoming request, and delegates processing of that request to one of a number of handlers, the mapping of which is specific in the DispatcherServlet configuration.
