spring mvc and springboot mvc

[David Mutansan]

I used Spring MVC before and I know usually I creat a web.xml defining "DispatchServlet", and in my  "myapp-servlet.xml" I define the controllers and view resolvers, etc.  However when I was learning sprintboot, it can alsodo MVC work using "ModelAndView" in its @Controller class, but it seems it doesn't require me to explicitly create "DispatchServlet" or even a web.xml file, nor do i need to create a "myapp-servlet.xml" file.  Is it true and why ? I suppose they are both using Spring MVC..

In our recent versions of Spring Framework or Spring Boot, web.xml and myapp-servlet.xml are optional.
You can use annotations like @Controller , @Component and etc to define beans.
Spring boot can autoconfigure data source. dispatcher servlet and some other resources for you to
save you some development time.
