title: Is customizing DispatcherServlet in Spring MVC a common practice?
body: <p>I am new to Spring MVC. But I had certain experience in working with Struts 1.x. I would like to know if it is a common practice to customize <strong>DispatcherServlet</strong> while working with Spring MVC, like people sometimes customize <strong>ActionServlet</strong> or <strong>RequestProcessor</strong> in Struts 1.x?</p>
  
  <p>Or let's extend the question a little bit. Where are the entry points for a veteran Spring MVC programmer to customize the MVC framework?</p>
  
  <p>Thank you.</p>
