在redis缓存中获取wirh键时获取null值

Question

我的项目在春季自定义OAuth2，所以当用户登录时，我返回自定义访问和刷新令牌并将其保存到缓存（这里我使用redis进行缓存）。我的Redis配置是：

@Configuration
public class CachingConfiguration {
    @Autowired
    private RedisConfigureSerializer  configureSerializer;


    @Bean
    public RedisConnectionFactory jedisConnectionFactory() {

            GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
            poolConfig.setMaxTotal(100);
            poolConfig.setBlockWhenExhausted(false);

            RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
            redisStandaloneConfiguration.setHostName("localhost");
            redisStandaloneConfiguration.setPort(6379);
jedisClientConfiguration = JedisClientConfiguration.builder();
            jedisClientConfiguration.usePooling();
            jedisClientConfiguration.build();

            JedisConnectionFactory jedisConFactory = new JedisConnectionFactory(redisStandaloneConfiguration,
                    jedisClientConfiguration
                            .usePooling()
                            .poolConfig(poolConfig)
                            .build());

            return jedisConFactory;
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(jedisConnectionFactory());
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(configureSerializer);
        return template;
    }

    @Bean
    public RedisCacheManager cacheManager() {
        Map<String, RedisCacheConfiguration> map = new HashedMap();
        map.put("accessTokenCache", redisCacheConfiguration());
        RedisCacheManager cacheManager = RedisCacheManager.builder(RedisCacheWriter.lockingRedisCacheWriter(jedisConnectionFactory()))    
.withInitialCacheConfigurations(map)              
                .transactionAware()
                .build();

        return cacheManager;
    }

    private RedisCacheConfiguration redisCacheConfiguration() {
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofDays(duration))
                .disableCachingNullValues();

        return config;
    }

Class实现缓存

@EnableCaching
public class RedisCaching implements TokenStore, InitializingBean {
     accessTokenCache = redisCacheManager.getCache("accessTokenCache");
        accessTokenCache.put("1", "Hello1");//in debug mode, i put data in to cach and get value, it's ok

@Override
    public void storeAccessToken(OAuth2AccessToken token, OAuth2Authentication authentication) {
    accessTokenCache.put("2", "Hello2");//in debug mode, i put data into cach ok but get value by key return null value
}

}
