1、springboot 外围依赖最新版本：
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，同时保障单点、多点登录，token 认证胜利之后对于雷同的用户信息返回的 token 值是一样的，不适宜在多地同时登录。
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<String, String> values = new LinkedHashMap<String, String>();OAuth2Request authorizationRequest = authentication.getOAuth2Request();
if (!authentication.isClientOnly()) {
// 在用户名前面增加工夫戳，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<String>(authorizationRequest.getScope())));}
return generateKey(values);}
}
public TokenStore tokenStore() {
RedisTokenStore redisTokenStore = new RedisTokenStore(redisConnectionFactory);redisTokenStore.setAuthenticationKeyGenerator(new MyAuthenticationKeyGenerator());
return redisTokenStore;
}
