No message available JSP SpringBoot - spring

Question

I've been looking through almost every post that is related to my problem and tried every solution that i've found and this problem keeps appearing.
I'm developing a web application and i have almost all the pages that will include, but when i try to connect the Controllers with any JSP this messages appears every time, so i created a new project with only one table and a couple pages, and still get the same "error" but only with pages that load some information, i've tried with one very simple page and it works
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
There was an unexpected error (type=Not Found, status=404).

Answer 1

Based on your Controller mapping when you hit
localhost:8080/ => inicio page will load
localhost:8080/listcte => indexpac page will load
localhost:8080/newcte => nuevopac page will load
Now let's see what you were trying
localhost:8080/listado => will throw error page as no mapping is found for this URL in Controller class.
localhost:8080/newcte => should load nuevopac page. Check console for error and please add nuevopac code. May be JSP throwing some error.

Answer 2

Replace in your Controller Client class #Controller for #RestController
