Spring boot security custom messages while user login - spring

Question

I am trying to integrate spring security in my spring boot application.All working ok but how do I display a message if the account is expired or account is locked? Also, I do not want to display error message based on parm like http://localhost:8080/login?error
Here is my current code: login.html
<div th:if="${param.error}" class="alert alert-danger">
Invalid username or password.
</div>
<h3>Sign in to continue</h3>
<form th:action="#{/login}" name="loginForm" method="POST">
<div class="form-group">
<label for="userNameInput">Username</label>
<input type="text" class="form-control" id="userNameInput" name="username" placeholder="Username" />
</div>
<div class="form-group">
<label for="passwordInput">Password</label>
<input type="password" class="form-control" id="passwordInput" name="password" placeholder="Password" />
</div>
<button type="submit" class="btn btn-success">Login</button>
</form>
WebSecurityConfig.java
#Configuration
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Autowired
private CustomUserDetailsService customUserDetailsService;
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/", "/css/**", "/js/**","/login/**").permitAll()
.anyRequest().authenticated()
.and().formLogin().loginPage("/login").defaultSuccessUrl("/dashboard")
.and().logout().logoutSuccessUrl("/");
}
#Autowired
public void configAuthBuilder(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(customUserDetailsService).passwordEncoder(new BCryptPasswordEncoder());
}
}
CustomUserDetailsService.java
#Service
public class CustomUserDetailsService implements UserDetailsService {
#Autowired
UserRepository userRepository;
#Override
#Transactional(readOnly = true)
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
//query for user from DB
User user = userRepository.findByUsername(username);
if (user == null) {
throw new UsernameNotFoundException(username);
}
Date today = new Date();
//do check if account expired / suspended / deleted
Boolean isAcconutExpired = false;
Boolean status = false;
if (user.getExpireOn() != null && today.before(user.getExpireOn())) {
isAcconutExpired = false;
}
if(user.getStatus() == 1){
status = true;
}
return new org.springframework.security.core.userdetails.User(user.getUsername(),
user.getPassword(),
status,
!isAcconutExpired,
true,
true,
getAuthorities(user));
}
private List<GrantedAuthority> getAuthorities(User user) {
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.add(new SimpleGrantedAuthority("USER"));
return authorities;
}
}
UserRepository.java
#Repository
public interface UserRepository extends CrudRepository<User, Long> {
User findByUsername(String username);
}

This message is a bit old, but I'm currently facing the same problem.
So, firstly, you have to create a custom instance of Authentication Provider to let HideUserNotFoundExceptions be passed to the controler:
public AuthenticationProvider daoAuthenticationProvider() {
DaoAuthenticationProvider impl = new DaoAuthenticationProvider();
impl.setUserDetailsService(customUserDetailsService);
impl.setPasswordEncoder(new BCryptPasswordEncoder());
impl.setHideUserNotFoundExceptions(false) ;
return impl ;
}
Moreover, you should add this provider in the AuthenticationProviderBuilder, instead of adding customDetailService (adding customDetailService will add an other provider) :
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(daoAuthenticationProvider());
}
With this, you can now catch UserNotFoundException instead of basic BadCredentialsException .
So, it remains to display custom error message for these two exceptions. The Badcredentials exception is throw directly by SpringSecurity with an error message based on I18n message AbstractUserDetailsAuthenticationProvider.badCredentials (see the implementation in spring security here ):
throw new BadCredentialsException(this.messages.getMessage("AbstractUserDetailsAuthenticationProvider.badCredentials", "Bad credentials"));
Same for expiration and account locked.
So I suggest you to change your CustomUserDetailsService.java class to do the same with a similar code error :
if (user == null) {
throw new UsernameNotFoundException(SpringSecurityMessageSource.getAccessor().getMessage("AbstractUserDetailsAuthenticationProvider.UserUnknown",new Object[] {login},"User is not known"));
}
After this, you can add these lines in your message.properties :
AbstractUserDetailsAuthenticationProvider.UserUnknown = {0} was not found.
AbstractUserDetailsAuthenticationProvider.badCredentials = Password is bad
AbstractUserDetailsAuthenticationProvider.credentialsExpired = User credentials have expired
AbstractUserDetailsAuthenticationProvider.disabled = User is disabled
AbstractUserDetailsAuthenticationProvider.expired = User account has expired
AbstractUserDetailsAuthenticationProvider.locked = User account is locked
And display error message in login.html :
<div class="dialog-row">
<label th:if="${param.error}" th:text="${session['SPRING_SECURITY_LAST_EXCEPTION'].message}" class="text-center redText">Mot de passe inconnu</label>
</div>
