This application has no explicit mapping for /error, so you are seeing this as a fallback.

issue.

The thing is in my security configuration I understand I have to modify this line :

 .formLogin(form -> form

                // Redirect the user if successfull authentication
                            .defaultSuccessUrl("/",true)
                            
                )
                .logout(config-> config.logoutSuccessUrl("/"))
                // Redirect the user if log the fuck out
                .build();

 .formLogin(form -> form

                // Redirect the user if successfull authentication
                            .defaultSuccessUrl("/",true)
                            
                )
                .logout(config-> config.logoutSuccessUrl("/"))
                // Redirect the user if log the fuck out
                .build();

But my home URL is

http://localhost:8080/

http://localhost:8080/

do you know how to modify the url to at least redirect it to the homepage ( I built my environment with Maven ) ?
