Closed 6 years ago.
I am creating a simple login page with model and controller using maven, Spring 3.1.1. I have just created a model and controller. But while running the application I get a 404 error in my browser and in console I am getting the following error:
org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/TEST2/] in DispatcherServlet with name 'dispatcher'
I have checked the configuration properly and I couldn't find the exact error for this.
I have changed some of the configuration. I tried putting /* in URL-Mapping but I am facing the same issue.

String name=request.getParameter("name");

if("concretepage".equalsIgnoreCase(name)&&"concretepage".equalsIgnoreCase(pwd)){
model.addAttribute("message", "Successfully logged in.");
}else{
model.addAttribute("message", "Username or password is wrong.");
}
return "redirect:success.jsp";
}
}
What's my mistake?

You have not placed the Mapping for root path '/'
change this code
#RequestMapping(value="/login", method = RequestMethod.GET)
public String login(){
return "redirect:pages/login.jsp";
}
into
#RequestMapping(value="/", method = RequestMethod.GET)
public String login(){
return "redirect:pages/login.jsp";
}
and check the output.
