Spring boot - how to configure multiple login pages?

With my team, we created a Spring application + SAPUI5 portal using Spring Boot. For example, a web application is broken down into three separate locations:

WebApp: - app1 - app2 - app3

To access these applications, we have implemented a login page. Based on the user's role, we redirect users to the exact application.

My Spring security looks like this:

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/app1/**/*.*")
                .permitAll()
                .antMatchers("/register.html")
                .permitAll()
                //
                .antMatchers("/app2/*.*")
                .hasRole("USER")
                //
                //
                .antMatchers("/login*")
                .permitAll()
                .antMatchers("/soap/*")
                .permitAll()
                .antMatchers("/postLogin")
                .authenticated()
                //
                .antMatchers("/app3/*")
                //.permitAll()
                .hasRole("ADMIN")
                //
                .anyRequest()
                .authenticated()
                // log in
                .and()
                .formLogin()
                .loginPage("/login")
                .failureUrl("/login?error=loginError")
                .defaultSuccessUrl("/postLogin")
                // logout
                .and().logout().logoutUrl("/**/logout")
                .logoutSuccessUrl("/login").deleteCookies("JSESSIONID").and()
                .csrf()
                .disable()

      

        
        
        
      

    

and of course we have a class with a redirect. We now need to provide a different login page for each application. I tried to configure Spring Security to accept multiple login forms on different pages, but that doesn't work. Is it possible? I've read the documentation, but it's not convincing.
