Custom authentication page Spring security

Question

I added the spring security dependency to my POM.XML, after which I created a new custom page for user authentication and configured webSecurityConfig to search my custom page, but when running the program he opens me the default page created by spring S itself.

My html login page is called html., so on my getMapping I put it like this:

@GetMapping("/")
    public String entrar() {
        return "entrar";
    }

(At the end, when ordering something for the application’s '/' I would like to open my custom page instead of the spring pattern)

In my configuration class Websecurityconfig did so:

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.
            authorizeRequests()
                .anyRequest()
                .authenticated()
            .and()
            .formLogin()
                .loginPage("/entrar")
                .permitAll();
    }
}

Should spring no longer open my custom authentication page? I mean, Login.html I created? It turns out that even after having done these steps the Framework continues to open the default Spring page.

Can anyone tell me if what I did wrong or if I missed something?
