@Bean
public TokenEnhancer tokenEnhancer() {
    return (accessToken, authentication) -> {
        Map<String, Object> map = new HashMap<>(2);
        User user = (User) authentication.getUserAuthentication().getPrincipal();
        map.put(AuthConstants.JWT_USER_ID_KEY, user.getId());
        map.put(AuthConstants.JWT_CLIENT_ID_KEY, user.getClientId());
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(map);
        return accessToken;
    };
}

private Collection<SimpleGrantedAuthority> authorities;

public User(UserDTO user) {
    this.setId(user.getId());
    this.setUsername(user.getUsername());
    this.setPassword(AuthConstants.BCRYPT + user.getPassword());
    this.setEnabled(Integer.valueOf(1).equals(user.getStatus()));
    this.setClientId(user.getClientId());
    if (CollectionUtil.isNotEmpty(user.getRoles())) {
        authorities = new ArrayList<>();
        user.getRoles().forEach(roleId -> authorities.add(new SimpleGrantedAuthority(String.valueOf(roleId))));
    }
}
