Security configuration with spring boot - spring-boot

Question

I'm a beginner, I want to code the password when adding users but there is an error (#Bean).
Error:
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Description:
Field passwordEncoder in com.example.demo.service.UsersService required a bean of type 'org.springframework.security.crypto.password.PasswordEncoder' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'org.springframework.security.crypto.password.PasswordEncoder' in your configuration.
My code:
#Configuration
#EnableConfigurationProperties
#EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true, jsr250Enabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
UsersService userService;
#Override
protected void configure(HttpSecurity http) throws Exception {
// TODO Auto-generated method stub
http.csrf().disable() //TODO implement csrf
.cors().and().authorizeRequests().antMatchers(HttpMethod.OPTIONS,"/").permitAll()
.antMatchers("/login").permitAll()
.antMatchers("/add-users").permitAll()
.and().authorizeRequests().anyRequest().authenticated();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// TODO Auto-generated method stub
auth.userDetailsService(userService)
.passwordEncoder(passwordEncoder());
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
// TODO Auto-generated method stub
return super.authenticationManagerBean();
}
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
public class UsersService implements UserDetailsService {
#Autowired
UsersRepository repo;
#Autowired
private PasswordEncoder passwordEncoder;
public Users save(Users u) {
String encodpass=passwordEncoder.encode(u.getPassword());
String confpass=passwordEncoder.encode(u.getConfirmepass());
u.setConfirmpass(confpass);
u.setPassword(encodpass);
u.setLock(false);
u.setEnable(true);
return repo.save(u);
}
}
#RestController
public class UsersController {
#Autowired
private UsersService service;
#PostMapping("/add-users")
public Users add(#RequestBody Users u) {
return service.save(u);}

Answer 1

The problem is that in your SecurityConfiguration you are injecting UsersService, and the UserService bean depends on a bean of type PasswordEncoder that has not been created yet.
I'll simplify your configuration by using a more ellegant way of configuring Spring Security:
#Configuration
//your other annotations
public class SecurityConfiguration {
#Bean
public SecurityFilterChain app(HttpSecurity http) throws Exception {
http.csrf().disable().cors().and().authorizeRequests().antMatchers(HttpMethod.OPTIONS,"/").permitAll()
.antMatchers("/login").permitAll()
.antMatchers("/add-users").permitAll()
.and().authorizeRequests().anyRequest().authenticated();
}
#Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
}
And that's it, you don't really need the AuthenticationManager bean unless you are actually using it. In case that you need it, you can create it like this:
#Bean
public AuthenticationManager authenticationManager(UsersService usersService) {
DaoAuthenticationProvider daoAuthenticationProvider = new DaoAuthenticationProvider();
daoAuthenticationProvider.setUserDetailsService(usersService);
ProviderManager manager = new ProviderManager(daoAuthenticationProvider);
return manager;
}
I apologize for any compilation error beforehand because I wrote this from a phone.

Answer 2

add #Service annotation to UserService class. also add #EnableWebSecurity to config class.
