UserService

public interface UserService extends UserDetailsService {

}

UserServiceImpl

@Service
public class UserServiceImpl implements UserService {

    private UserRepo userRepo;

    @Autowired
    public void setUserRepo(UserRepo userRepo) {
        this.userRepo = userRepo;
    }

    @Override
    public UserDetails loadUserByUsername(String username)
            throws UsernameNotFoundException {
        User user=userRepo.findUserByUsername(username);
        if(user == null) {
            throw new UsernameNotFoundException("Could not find user " + username);
        }
        return new CustomUser(user);
    }

    public final static class CustomUser extends User implements UserDetails
    {
        public CustomUser(User user) {
            super(user);
        }

        @Override
        public Collection<? extends GrantedAuthority> getAuthorities() {
            List<GrantedAuthority> authorities=new ArrayList<GrantedAuthority>();
            List<Role> roles=new ArrayList<Role>(getRoles());

            for(Role role:roles)
                authorities.add(new SimpleGrantedAuthority(role.getRole()));

            return authorities;
        }

        @Override
        public boolean isAccountNonExpired() {
            return true;
        }

        @Override
        public boolean isAccountNonLocked() {
            return true;
        }

        @Override
        public boolean isCredentialsNonExpired() {
            return true;
        }       
    }
}

SecurityConfig

@Configuration
@EnableWebSecurity
@ComponentScan(basePackageClasses=UserServiceImpl.class)
public class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth)
            throws Exception {

        auth
            .userDetailsService(userDetailsService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers(HttpMethod.GET, "/","/index","/register","/public/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/");

    }
}

登录失败，出现错误凭据异常。当我使用 jdbcAuthentication（）而不是自定义用户服务时，登录工作正常。实际上，我不知道为什么我应该编写实现 UserDetailsS​​ervice 的自定义用户服务。我只是遵循以这种方式编写的教程，而不是jdbcAuthentication（）。

有什么建议吗？
