Autentificering med Spring Security + Spring data + MongoDB

Servicelag

Du skal oprette en separat service implementering af org.springframework.security.core.userdetails.UserDetailsService og injicer det i AuthenticationManagerBuilder .

@Component
public class SecUserDetailsService implements UserDetailsService{

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        /*Here add user data layer fetching from the MongoDB.
          I have used userRepository*/
        User user = userRepository.findByUsername(username);
        if(user == null){
            throw new UsernameNotFoundException(username);
        }else{
            UserDetails details = new SecUserDetails(user);
            return details;
        }
    }
}

Model

UserDetails Bør også implementeres. Dette er POJO'en, som vil holde brugerens autentificerede detaljer inden foråret. Du kan inkludere dit Entity-dataobjekt pakket inde i det, som jeg har gjort.

public class SecUserDetails implements UserDetails {

    private User user;

    public SecUserDetails(User user) {
        this.user = user;
    }
    ......
    ......
    ......
}

Sikkerhedskonfiguration

Autowire tjenesten, som vi oprettede før, og sæt den i AuthenticationManagerBuilder

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    SecUserDetailsService userDetailsService ;

    @Autowired
    public void configAuthBuilder(AuthenticationManagerBuilder builder) throws Exception {
        builder.userDetailsService(userDetailsService); 
    }
}
