title: spring-boot - Which piece of code actually register dispatcher servlet for springMVC?
body: <p>I am trying to find out in <code>spring-boot</code>, which implementation of <code>WebApplicationInitializer</code> actually register the dispatcher servlet.</p>
  
  <p>I didn't found any piece code from <code>SpringBootServletInitializer</code> or its parent types did that.</p>
  
  <p>Instead, <code>AbstractDispatcherServletInitializer</code> does the job, but it's abstract, I can't find any of its concrete implementation with help of Eclipse.</p>
  
  <p>So, which piece of code from which class is actually invoked to register the dispatcher servlet for springMVC?</p>
