Spring security handles secure login via WebSecurityConfig.configure - a login controller is uneeded.

Will have to provide links to frontend logon via configure

protected void configure(HttpSecurity http) throws Exception {
        // TODO handle login and auth requests through front-end webpages
        http
                .csrf().disable()
                .authorizeRequests()
                    .antMatchers("/api/v*/register/**").anonymous() // Difference between anonymous & permit all?
                    .antMatchers("/api/v*/login/**").permitAll()
                .anyRequest()
                .authenticated().and()
                .formLogin();
