The origin server did not find a current representation for the target resource or is not willing to disclose that one exists

Question

web.xml

Answer 1

the problem is in url pattern of servlet-mapping.

 /DispatcherServlet

let's say our controller is

@Controller
public class HomeController {
    @RequestMapping("/home")
    public String home(){
        return "home";
    }
}

when we hit some URL on our browser. the dispatcher servlet will try to map this url.

the url pattern of our serlvet currently is /Dispatcher which means resources are served from {contextpath}/Dispatcher

but when we request http://localhost:8080/home we are actually asking resources from / which is not available. so either we need to say dispatcher servlet to serve from / by doing

/

our make it serve from /Dispatcher by doing /Dispatcher/*

E.g

  springsecuritydemo

  
    
    offers
    offers
    org.springframework.web.servlet.DispatcherServlet
    1
  
  
    offers
    /Dispatcher/*
  

and request it with http://localhost:8080/Dispatcher/home or put just / to request like

http://localhost:8080/home
