Spring Security系列(27)- Spring Security Oauth2之令牌过期和续签问题解决方案(1)_云烟成雨TD的博客-CSDN博客_怎么解决令牌已经过期Spring Security Oauth2 令牌机制Spring Security Oauth2利用令牌机制来实现认证授权及单点登录,获取到令牌后,携带令牌访问资源服务器,资源服务器针对每次访问,都会用令牌去查询认证信息,然后设置到线程SecurityContextHolder中,后续操作都会获取到用户信息,简单流程入下图所示:令牌过期问题问题在之前,我们分析过,申请到的令牌都是具有过期时间的,在返回的令牌是有字段显示其多久后会过期,单位为秒而这个过期时间,默认是无法修改的,如果用户一直在操https://yunyanchengyu.blog.csdn.net/article/details/121349989本文在上文的基础上做了修改。原文中是自己定义了一个 ResourceServerTokenServices 接口的实现类,而我在实践中发现需要的是一个 AuthorizationServerTokenServices 接口的实现类,可能是版本不同导致的,这点我没有去求证。方便起见,我定义了一个 DefaultTokenServices 的子类,因为 DefaultTokenServices 同时实现了上面提到的两个接口,所以都可以使用。以下是子类的代码:
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.common.exceptions.InvalidTokenException;
import org.springframework.security.oauth2.provider.ClientDetails;
import org.springframework.security.oauth2.provider.ClientDetailsService;
import org.springframework.security.oauth2.provider.ClientRegistrationException;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.DefaultTokenServices;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
* 实现用户有操作时 token 自动续期
*/
@Component
@ConditionalOnProperty(prefix = "token.auto-renew", name = "enabled", havingValue = "true")
public class CustomResourceServerTokenServices extends DefaultTokenServices {
private TokenStore tokenStore;
private ClientDetailsService clientDetailsService;
@Value("${token.auto-renew.interval}")
private int interval;
public CustomResourceServerTokenServices(TokenStore tokenStore) {
super.setTokenStore(tokenStore);
this.tokenStore = tokenStore;
}
@Override
public void setClientDetailsService(ClientDetailsService clientDetailsService) {
super.setClientDetailsService(clientDetailsService);
this.clientDetailsService = clientDetailsService;
}
@Override
public OAuth2Authentication loadAuthentication(String accessTokenValue) throws AuthenticationException, InvalidTokenException {
DefaultOAuth2AccessToken accessToken = (DefaultOAuth2AccessToken) tokenStore.readAccessToken(accessTokenValue);
if (accessToken == null) {
throw new InvalidTokenException("Invalid access token: " + accessTokenValue);
} else if (accessToken.isExpired()) {
tokenStore.removeAccessToken(accessToken);
throw new InvalidTokenException("Access token expired: " + accessTokenValue);
}
OAuth2Authentication result = tokenStore.readAuthentication(accessToken);
if (result == null) {
// in case of race condition
throw new InvalidTokenException("Invalid access token: " + accessTokenValue);
}
if (clientDetailsService != null) {
String clientId = result.getOAuth2Request().getClientId();
try {
ClientDetails clientDetails = clientDetailsService.loadClientByClientId(clientId);
Date nowTokenExpiration = accessToken.getExpiration();
Date now = new Date();
// 如果过期时间少于5分钟,则重新设置令牌对象的过期时间,并存储
if ((nowTokenExpiration.getTime() - now.getTime()) < (interval * 1000L)) {
// 刷新过期时间
Date expiration = new Date(System.currentTimeMillis() + clientDetails.getAccessTokenValiditySeconds() * 1000L);
accessToken.setExpiration(expiration);
// 设置新的令牌 会自动再根据令牌对象过期时间设置 redis过期
tokenStore.storeAccessToken(accessToken, result);
}
} catch (ClientRegistrationException e) {
throw new InvalidTokenException("Client not valid: " + clientId, e);
}
}
return result;
}
}
有几点需要说明:
- 基于配置文件决定是否启用此功能,只在开启的时候向容器注入该 Bean
-
DefaultTokenServices 实现了 InitializingBean 接口,在 afterPropertiesSet 方法中判 tokenStore 是否为空,所以需要在子类的构造方法中配置父类的 tokenStore -
同样的,clientDetailsService 也需要配置父类,但没必要在构造时配置 -
loadAuthentication 方法的逻辑在原方法的逻辑上添加了 token 续期的逻辑
既然基于配置文件决定是否启用此功能,那么 Configurer 也需要做一些改动:
public class Configurer extends AuthorizationServerConfigurerAdapter {
@Autowired
private DefaultTokenServices tokenServices;
@Bean
@ConditionalOnMissingBean(DefaultTokenServices.class)
public DefaultTokenServices defaultTokenServices() {
DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
defaultTokenServices.setTokenStore(tokenStore);
return defaultTokenServices;
}
}
另外,可以对外提供一个接口来实现定期续期 token,接口的逻辑如下:
@Autowired
private TokenStore tokenStore;
@Autowired
private ClientDetailsService clientDetailsService;
public void renewToken() {
String token = SecurityUtils.getToken();
if (StringUtils.isNotBlank(token)) {
DefaultOAuth2AccessToken accessToken = (DefaultOAuth2AccessToken) tokenStore.readAccessToken(token);
OAuth2Authentication authentication = tokenStore.readAuthentication(accessToken);
String clientId = authentication.getOAuth2Request().getClientId();
ClientDetails clientDetails = clientDetailsService.loadClientByClientId(clientId);
// 刷新过期时间
Date expiration = new Date(System.currentTimeMillis() + clientDetails.getAccessTokenValiditySeconds() * 1000L);
accessToken.setExpiration(expiration);
// 设置新的令牌 会自动再根据令牌对象过期时间设置 redis过期
tokenStore.storeAccessToken(accessToken, authentication);
}
}
