SpringBoot 2.1.3 Security multiple available login page for first authentication - spring-boot

Question

I'm developing a SpringBoot 2.1.3 + Thymeleaf 3 + Tomcat 8 WebApp. I have implemented Spring Security and all works well. Now I have a little problem because I want to realize two form login page, one for backoffice users and other one for all others users.
I don't wanna put both form in the same page, and like to create a page with a simple form for backoffice users and a link that redirect to another page (with another form) for customer users.
I have read some and I have found just a way to Ordering the WebSecurityConfigurerAdapter and creating multiple entry point but this way, I can log in with page with order 1 and then I can go the the other form page. It'isnt what I want to do.
Do you know if there is a way to do this??
Thank you

Answer 1

I found a way and it is pretty simple. I have configured the WebSecurityConfigurerAdapter as follow:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/login-procout").permitAll() // login for furnishers
.anyRequest().authenticated()
.and()
.formLogin().loginPage("/login-officers") // default login page
.permitAll()
.successHandler(customAuthenticationSuccessHandler())
.and()
.logout()
.permitAll();
http.csrf().disable();
}
Then I create two html page login-officers.html and login-procout.html referred by Controller as follow:
#Controller
public class MyController {
#GetMapping("/login-officers")
public String loginOfficers() {
return "login-officers";
}
#GetMapping("/login-procout")
public String loginProcout() {
return "login-procout";
}
}
And in both page I have default Spring Security Form:
<form action="" th:action="#{/login}" method="post">
<input type="text" name="username" id="username" placeholder="Username"/>
<input type="password" name="password" id="password" placeholder="Password"/>
<input type="submit" id="login" value="Log In" />
</form>
I don't know if is the right way to do but it works.
