Error 404 - Not Found Spring MVC application

I'm getting the error

  

Error 404 - Not Found: The server has not found anything matching the Request-URI

When trying to access any url of my application, the strange thing is that the index.jsp page works normally, including loading the resources that I set in springmv-servlet.xml .

Project structure:

}
