I am trying to use the new Component-Based (Without WebSecurityConfigurerAdapter) configuration and setted up my Security Configuration as follow:
SecurityConfiguration.java file
package com.tito.userservice.security;
import com.tito.userservice.filter.CustomAuthenticationFilter;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;
@Configuration @EnableWebSecurity @RequiredArgsConstructor
public class SecurityConfiguration {
private final UserDetailsService userDetailsService;
private final BCryptPasswordEncoder bCryptPasswordEncoder;
private final AuthenticationManagerBuilder authManagerBuilder;
@Bean
public PasswordEncoder encoder() {
return new BCryptPasswordEncoder();
}
//----------------HTTP SECURITY CONFIG-------------------------------------
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.csrf().disable();
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
http
.authorizeRequests().anyRequest().permitAll();
http.addFilter(new CustomAuthenticationFilter(authManagerBuilder.getOrBuild()));
return http.build();
}
//----------------HTTP SECURITY CONFIG-------------------------------------
}
but when I run the application and try to log a user the following error appears even though I have the BCryptPasswordEncoder as a bean in my SecurityConfiguration:

Which is the correct way to set up the PasswordEncoder in the new component-configuration?
Edit: adding login logic
AppUserService interface
package com.tito.userservice.services;
import com.tito.userservice.domain.AppUser;
import com.tito.userservice.domain.Role;
import java.util.List;
public interface AppUserService {
AppUser saveUser(AppUser user);
Role saveRole(Role role);
void addRoleToUser(String username, String roleName);
AppUser getUser(String username);
List<AppUser>getUsers();
}
and the AppUserServiceImplementation:
package com.tito.userservice.services;
import com.tito.userservice.domain.AppUser;
import com.tito.userservice.domain.Role;
import com.tito.userservice.repo.AppUserRepo;
import com.tito.userservice.repo.RoleRepo;
import lombok.RequiredArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Service;
import javax.transaction.Transactional;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;
@Service @RequiredArgsConstructor @Transactional @Slf4j
public class AppUserServiceImpl implements AppUserService, UserDetailsService {
private final AppUserRepo appUserRepo;
private final RoleRepo roleRepo;
private final PasswordEncoder passwordEncoder;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
AppUser user =appUserRepo.findByUsername(username);
if (user == null){
log.error("User not found in the database");
throw new UsernameNotFoundException("User not found in the databse");
}else {
log.info("User found in the database: {}",username);
}
Collection<SimpleGrantedAuthority> authorities = new ArrayList<>();
user.getRoles().forEach(role -> {
authorities.add(new SimpleGrantedAuthority(role.getName()));
});
return new org.springframework.security.core.userdetails.User(user.getUsername(), user.getPassword(), authorities);
}
@Override
public AppUser saveUser(AppUser user) {
log.info("Saving new user {} to the database",user.getName());
user.setPassword(passwordEncoder.encode(user.getPassword()));
return appUserRepo.save(user);
}
@Override
public Role saveRole(Role role) {
log.info("Saving new role {} to the database",role.getName());
return roleRepo.save(role);
}
@Override
public void addRoleToUser(String username, String roleName) {
log.info("Adding role {} to user {}",roleName,username );
//real life could be good, or must be good, to do validation of below
AppUser user = appUserRepo.findByUsername(username);
Role role = roleRepo.findByName(roleName);
user.getRoles().add(role);
}
@Override
public AppUser getUser(String username) {
log.info("Fetching user {}",username );
return appUserRepo.findByUsername(username);
}
@Override
public List<AppUser> getUsers() {
log.info("Fetching all users");
return appUserRepo.findAll();
}
}
Edit2: added CustomAuthenticationFilter.java code

Answer
Judging by the stacktrace I assume your CustomAuthenticationFilter calls AuthenticationManager.authenticate() method on a UsernamePasswordAuthenticationToken object. That, by default, calls DaoAuthenticationProvider, which is created with a DelegatingPasswordEncoder, containing 11 password encoders, and which is trying to match passwords with this encoder (not your BCryptPasswordEncoder bean).
This DelegatingPasswordEncoder tries to match stored password, retrieved from your UserDetailsService, and it assumes your password is stored with a key (prefix), like this:
{bcrypt}encodedPassword
You’ve registered a bean of type BCryptPasswordEncoder and you’re encoding your password with it, so passwords are stored without {bcrypt} prefix (just the encoded password is stored), and when calling AuthenticationManager.authenticate() mentioned DelegatingPasswordEncoder sees null prefix and cannot find the corresponding PasswordEncoder in a map – that’s what the error message is about.
So you can define a PasswordEncoder bean as a DelegatingPasswordEncoder, which, by default, uses BCryptPasswordEncoder to encode passwords.
Like this:
@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfiguration {
private final AuthenticationManagerBuilder authManagerBuilder;
@Bean
public PasswordEncoder encoder() {
return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}
}
That way stored passwords will have {prefix} and DaoAuthenticationProvider will be able to match passwords.
Also I advise to remove the BCryptPasswordEncoder field from your SecurityConfiguration class – you don’t need it there.
Also you can stuck with bean cycle dependencies, because your UserDetailsService injects PasswordEncoder, and PasswordEncoder is defined in a configuration, where UserDetailsService is injected, so you might also need refactoring.
For example, try to extract UserDetailsService:
@Service
@RequiredArgsConstructor
@Slf4j
public class UserDetailsServiceImpl implements UserDetailsService {
private final AppUserRepo appUserRepo;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// your logic here
return new User(username, password, authorities);
}
}
Or define a bean of this type UserDetailsService right in your SecurityConfiguration class:
@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfiguration {
private final AppUserRepo appUserRepo;
// other fields
@Bean
public UserDetailsService userDetailsService() {
return username -> {
// your logic here
return new User(username, password, authorities);
};
}
}
Also you can:
- instead of a custom filter create your own login endpoint, where you can check password matches using
BCryptPasswordEncoderdirectly; - create your own
AuthenticationProviderwith aBCryptPasswordEncoderas a password encoder and use it in yourCustomAuthenticationFilterto authenticate user.
