getIfPresent caffeine return null

@Autowired
Cache<Object, Object> caffeineCache; 

private void saveRequestToStorage(String key, Object value) {
 caffeineCache.put(key, value);
}

public Object getObjectFormInStorage(String key) {
return Optional.ofNullable(caffeineCache.getIfPresent(key)).orElseThrow(()
        -> new MbNotFoundException("error.msg.request.storage.not.found"));
}

i put value to cache in method 1 and get it in method 2 but method return null with same key in method 1. Anyone can help me?

Below is config

@Bean
public Caffeine caffeineCacheBuilder(LocalCacheConfigurationProperties properties) {
    return Caffeine.from(properties.getCaffeine().getSpec());
}

@Bean
public Cache<Object, Object> caffeineCache(Caffeine caffeineCacheBuilder) {
    return caffeineCacheBuilder.build();
}

@Bean
public CacheManager localCacheManager(Caffeine caffeineCacheBuilder, LocalCacheConfigurationProperties properties) {
    CaffeineCacheManager cacheManager = new CaffeineCacheManager();
    if (StringUtils.isEmpty(properties.getCacheNames())) {
        cacheManager.setCacheNames(null); // dynamic
    } else {
        cacheManager.setCacheNames(Arrays.asList(properties.getCacheNames()));
    }
    cacheManager.setCaffeine(caffeineCacheBuilder);
    return cacheManager;
}
