引入依赖
​

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>

</dependency>

修改application.yaml
​

spring:
  redis:
    host: 127.0.0.1
    database: 0

编写redis配置类
​

@Configuration
public class RedisConfig {
    @Autowired
    private RedisConnectionFactory redisConnectionFactory;
    @Bean
    public TokenStore tokenStore(){
        return new RedisTokenStore(redisConnectionFactory);
    }
}

在授权服务器配置中指定令牌的存储策略为Redis

@Autowired
private TokenStore tokenStore;
 
@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints.authenticationManager(authenticationManagerBean) //使用密码模式需要配置
        .tokenStore(tokenStore)  //指定token存储到redis
        .reuseRefreshTokens(false)  //refresh_token是否重复使用
        .userDetailsService(userService) //刷新令牌授权包含对用户信息的检查
        .allowedTokenEndpointRequestMethods(HttpMethod.GET,HttpMethod.POST); //支持GET,POST请求
}
