token 存储类 实现 AuthJdbcTokenStore
@Component
public class AuthJdbcTokenStore extends JdbcTokenStore {
public static final String USER_HAVE_TOKEN = "user-tokens:";
@Resource
RedisTemplate redisTemplate;
public AuthJdbcTokenStore(DataSource connectionFactory) {
super(connectionFactory);
}
@Override
public void storeAccessToken(OAuth2AccessToken token, OAuth2Authentication authentication) {
super.storeAccessToken(token, authentication);
if (Optional.ofNullable(authentication.getUserAuthentication()).isPresent()) {
User user = (User) authentication.getUserAuthentication().getPrincipal();
String userTokensKey = USER_HAVE_TOKEN + user.getUsername();
String tokenValue = token.getValue();
redisTemplate.opsForList().leftPush(userTokensKey, tokenValue);
Long seconds = redisTemplate.opsForValue().getOperations().getExpire(userTokensKey);
Long tokenExpTime = getExpTime(tokenValue);
Long expTime = seconds < tokenExpTime ? tokenExpTime : seconds;
redisTemplate.expire(userTokensKey, expTime, TimeUnit.SECONDS);
}
}
private long getExpTime(String accessToken) {
JWT jwt = JWTUtil.parseToken(accessToken);
cn.hutool.json.JSONObject jsonObject = jwt.getPayload().getClaimsJson();
long nowTime = Instant.now().getEpochSecond();
long expEndTime = jsonObject.getLong("exp");
long expTime = (expEndTime - nowTime);
return expTime;
}
}
oauth_access_token 使用 JdbcTokenStore 存储 token 需要新增表
CREATE TABLE `oauth_access_token` (
`create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
`token_id` varchar(255) DEFAULT NULL,
`token` blob,
`authentication_id` varchar(255) DEFAULT NULL,
`user_name` varchar(255) DEFAULT NULL,
`client_id` varchar(255) DEFAULT NULL,
`authentication` blob,
`refresh_token` varchar(255) DEFAULT NULL,
UNIQUE KEY `authentication_id` (`authentication_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3;
AuthorizationServerConfigurerAdapter 使用 AuthJdbcTokenStore 做 token 存储
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
@Autowired
private DataSource dataSource;
...
@Bean
public TokenStore tokenStore() {
JdbcTokenStore tokenStore = new AuthJdbcTokenStore(dataSource);
return tokenStore;
}
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
DefaultTokenServices tokenServices = new DefaultTokenServices();
tokenServices.setTokenStore(tokenStore());
endpoints
.authenticationManager(authenticationManager)
.tokenServices(tokenServices)
.accessTokenConverter(converter)
;
}
...
}
@Component
public class AuthLogoutSuccessHandler1 extends SimpleUrlLogoutSuccessHandler {
String USER_HAVE_TOKEN = AuthJdbcTokenStore.USER_HAVE_TOKEN;
@Resource
RedisTemplate redisTemplate;
@Resource
TokenStore tokenStore;
@Override
public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
if (!Objects.isNull(authentication)) {
String userName = authentication.getName();
String userTokensKey = USER_HAVE_TOKEN + userName;
Long size = redisTemplate.opsForList().size(userTokensKey);
List<String> list = redisTemplate.opsForList().range(userTokensKey, 0, size);
for (String tokenValue : list) {
OAuth2AccessToken token = tokenStore.readAccessToken(tokenValue);
if (Objects.nonNull(token)) {
tokenStore.removeAccessToken(token);
}
}
redisTemplate.delete(userTokensKey);
super.handle(request, response, authentication);
}
}
}
场景:项目运行一段时间后,发现登出时间越来越慢
问题:通过 debug 发现耗时主要在删除 token 那一段
tokenStore.removeAccessToken(token);
原因:随着时间推移,token 越来越多,token 存储表 oauth_access_token 变得异常的大,所以删除效率非常差
解决办法:使用其他 TokenStore,或者清除 oauth_access_token 的表数据
