s appearing instead of my custom login page. I have tried disabling the default login page by setting http.formLogin().disable() in my security configuration, but it doesn't seem to work. How can I disable the default login page and use my custom login page instead?

One possible solution is to create a custom authentication filter that will handle the authentication process and redirect to your custom login page if necessary. Here's an example of how you can do this:

1. Create a new class that extends UsernamePasswordAuthenticationFilter:

public class CustomAuthenticationFilter extends UsernamePasswordAuthenticationFilter {

    @Override
    public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException {
        // Your authentication logic here
        
        // If authentication fails, redirect to your custom login page
        if (!authenticationSuccess) {
            try {
                response.sendRedirect("/login");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        
        return super.attemptAuthentication(request, response);
    }
}

2. Update your security configuration to use the custom authentication filter:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.addFilterBefore(new CustomAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
        .formLogin().disable()
        // Other security configurations
}

By creating a custom authentication filter and handling the redirection to your custom login page within the filter, you can effectively disable Spring's default login page and use your own instead.
