Spring OAuth2 server : WebSecurityConfigurerAdapter how to allow another request than the login page - spring-boot

Question

I' d like to allow another page than the login one in my configuration, a registration page. I use the authorization_code grant to connect the users from another service, the client, so they are redirected to the oauth2 server to login then they are redirected back to the client.
I created a registration form accessible from the login page, but I 'm not able to reach it I' m automaticly redirected to the login page.
Here is my configuration
#Override
protected void configure(HttpSecurity http) throws Exception { // #formatter:off
http.requestMatchers()
.antMatchers("/login**", "/oauth/**")
.and()
.authorizeRequests()//autorise les requetes
.anyRequest()//pour n'importe quel path
.authenticated()//aux utilisateur authentifié
.and()
.formLogin()
.loginPage("/login")
.loginProcessingUrl("/login.do")
.usernameParameter("username")
.passwordParameter("password")
.permitAll()
.and()
.userDetailsService(userDetailsServiceBean());
}
I'd like to allow a /registration path but I don't know how to do that.
