1.Spring Security OAuth2存储token值的方式由多种，所有的实现方式都是实现了TokenStore接口
- InMemoryTokenStore:token存储在本机的内存之中
- JdbcTokenStore:token存储在数据库之中
- JwtTokenStore:token不会存储到任何介质中
- RedisTokenStore:token存储在Redis数据库之中
2.看下RedisTokenStore实现类在redis中存储了那些key,贴上源码如下：
private static final String ACCESS = "access:";
private static final String AUTH_TO_ACCESS = "auth_to_access:";
private static final String AUTH = "auth:";
private static final String REFRESH_AUTH = "refresh_auth:";
private static final String ACCESS_TO_REFRESH = "access_to_refresh:";
private static final String REFRESH = "refresh:";
private static final String REFRESH_TO_ACCESS = "refresh_to_access:";
private static final String CLIENT_ID_TO_ACCESS = "client_id_to_access:";
private static final String UNAME_TO_ACCESS = "uname_to_access:";
本案例是使用password、refresh_token模式，在Redis缓存*存储了9个键值对，其中有5个跟access_token相关，4个和refresh_token相关；
- access_token相关access:(OAuth2AccessToken)、auth:(OAuth2Authentication)、auth_to_access:(OAuth2AccessToken)、client_id_to_access:(OAuth2AccessToken)、uname_to_access:(OAuth2AccessToken)
- refresh_token相关refresh:(OAuth2RefreshToken)、refresh_auth:(OAuth2Authentication)、access_to_refresh(refresh_token):、refresh_to_access:(refresh_token)
3.通过查看RedisTokenStore源码（源码我就不贴出来了）的方式理解每个key所存储的数据
- access:中存储的键是access:be171b573f5a496ca601b32b1360fe84，值是OAuth2AccessToken对象序列化后的值
- 键是access:+access_token
- 值示例如下：
{ "access_token": "12833d6c89fb4ea58cbe7b6ada5de7b5", "token_type": "bearer", "refresh_token": "357304ee0a404700b3e65d547713011b", "expires_in": 898, "scope": "test" }
- auth_to_access:中存储的键是auth_to_access:a994f2a9a61186f32870e32d72a38d21，值是OAuth2AccessToken序列化后的值
-
键是auth_to_access:+ username、client_id、scope三个MD5加密后的值
-
值示例如下：
{ "access_token": "12833d6c89fb4ea58cbe7b6ada5de7b5", "token_type": "bearer", "refresh_token": "357304ee0a404700b3e65d547713011b", "expires_in": 898, "scope": "test" }
- auth:中存储的键是auth:be171b573f5a496ca601b32b1360fe84，值是OAuth2Authentication对象序列化后的值
- 键是auth:+access_token值
- 值示例如下：
