Spring security custom html login page not rendered - html

Question

i have followed this link for all configurations to set link up my custom html page for login. However, when i access localhost/login, i am faced with error status 500.
I am unable to render a simple html page when I access localhost:8080/login.
Are there extra configurations needed?
Should the html page be located at templates folder? How does the application know it should render "login.html" ?
Is my controller being recognised?
config
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.builders.WebSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
#EnableWebSecurity
#Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.anyRequest().fullyAuthenticated()
.and()
.formLogin()
.loginPage("/login")
.permitAll();
}
}
controller.
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
#Controller
public class LoginController {
#GetMapping("/login")
public String login() {
return "login";
}
}
replacing "login" above with below also shows error.
<h1> Login page <h1>

login.html is located in templates.
error message:
javax.servlet.ServletException: Circular view path [login]: would dispatch back to the current handler URL [/login] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

Answer 1

I have managed to resolve this. The main issue was because my artefactID was also named login. This resulted in all other context of "login", including "login.html" to be voided. I modified my controller to below and changing my html file to login2.html it worked.
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
#Controller
public class LoginController {
#GetMapping("/login")
public String login2() {
return "login2";
}
}
