通过密码授权类型获取访问令牌，当用户密码错误时，为什么授权服务器一直调用userdetailsservice

希望提示密码错误。
我的UserDetails服务是：

@Service
public class MyUserDetailsService implements UserDetailsService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userMapper.selectByUserName(username);
        User userRoles = userMapper.selectRolesById(user.getId());
        List<String> roles = userRoles.getRoles().stream().map(Role::getRole).collect(Collectors.toList());
        User userResourcePermissions = userMapper.selectResourcePermissionsById(user.getId());
        List<String> resourcePermissions = userResourcePermissions.getResourcePermissions().stream()
                .map(roleResourcePermissionRef -> String.format("%s:%s",roleResourcePermissionRef.getResourceCode(),roleResourcePermissionRef.getPermissionCode()))
                .collect(Collectors.toList());
        resourcePermissions.add("a1");
        UserDetails userDetails = org.springframework.security.core.userdetails.User
                .withUsername(user.getUserName())
                .password(user.getPassword())
                .roles(roles.toArray(new String[0]))
                .authorities(resourcePermissions.toArray(new String[0]))
                .build();
        return userDetails;
    }
}

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(myUserDetailsService)
                .passwordEncoder(passwordEncoder)
//                 .and().parentAuthenticationManager(authenticationManagerBean())
        ;
    }
}

由…引起的 .and().parentAuthenticationManager(authenticationManagerBean()) .
