How to throw user to a page other than /login if user is not authenticated in spring security - spring

Question

I wanted to throw users out on signup page instead of login page when they are not authenticated. One workaroud I did was to pass "/signup" in .loginPage() function in Security configuration of spring boot application.
But now I also need to put a .rememberMe() feature for login page. because of that I have to pass "/login" in .loginPage(). So that I can add .rememberMe() functionality.
To summarize, How can I throw non-authenticated users to /signup page as well as keeping the rememberMe functionality on login page?
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/game*/**").authenticated()
.antMatchers("/contest*/**").authenticated()
.antMatchers("/badges_awards").authenticated()
.antMatchers("/admin*/**").hasRole("ADMIN")
.and()
.formLogin()
.loginPage("/login")
.usernameParameter("emailAddress")
.passwordParameter("password")
.permitAll()
.and()
.rememberMe()
.key("remember-me")
.rememberMeParameter("remember-me")
.rememberMeCookieName("rememberlogin")
.and()
.logout()
.logoutUrl("/logout")
.logoutSuccessUrl("/")
.permitAll();
http.csrf().disable();
http.headers().frameOptions().disable();
}

Answer 1

Start your configuration like this to tell Spring Security that /signup URL does not need authentication and therefore won't be redirect to your login page :
http.authorizeRequests()
.antMatchers("/signup").permitAll()

Answer 2

try this
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/login.html").permitAll()
.antMatchers("/signup*/**").permitAll()
.and()
.formLogin()
.loginPage("/login")
.failureHandler(LoginAuthFailureHandler)
.and()
.exceptionHandling()
.accessDeniedPage("/signup.html");
}
#Component
public class LoginAuthFailureHandler extends SimpleUrlAuthenticationFailureHandler {
#Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response,
AuthenticationException exception) throws IOException, ServletException {
getRedirectStrategy().sendRedirect(request, response, "/signup.html");
}
}
