1、springboot 核心依赖最新版本：

Spring Boot 2.3.3

Spring Cloud Hoxton.SR8

Spring Cloud Alibaba 2.2.2

MybatisPlus 3.4.0

Element 2.3.12

2、更新auth认证时，更改，RedisTokenStore记录登录用户，同时保证单点、多点登录，token认证成功之后对于相同的用户信息返回的token值是一样的，不适合在多地同时登录。

重写DefaultAuthenticationKeyGenerator

public class AuthenticationKeyGenerator extends DefaultAuthenticationKeyGenerator {private static final String CLIENT_ID = "client_id";

private static final String SCOPE = "scope";

private static final String USERNAME = "username";

@Override

public String extractKey(OAuth2Authentication authentication) {Map values = new LinkedHashMap();

OAuth2Request authorizationRequest = authentication.getOAuth2Request();

if (!authentication.isClientOnly()) {//在用户名后面添加时间戳，使每次的key都不一样

values.put(USERNAME, authentication.getName()+System.currentTimeMillis());

}values.put(CLIENT_ID, authorizationRequest.getClientId());

if (authorizationRequest.getScope() != null) {values.put(SCOPE, OAuth2Utils.formatParameterList(new TreeSet(authorizationRequest.getScope())));

}return generateKey(values);

}

}

public TokenStore tokenStore() {RedisTokenStore redisTokenStore = new RedisTokenStore(redisConnectionFactory);

redisTokenStore.setAuthenticationKeyGenerator(new MyAuthenticationKeyGenerator());

return redisTokenStore;

}
