i 'm building a cache using LoadingCache

 dataCache = CacheBuilder.newBuilder().expireAfterWrite(600, TimeUnit.MINUTES)
                .maximumSize(SystemInfoLocal.CACHE_SIZE)
                .build(new CacheLoader<String, String[]>() {
                    @Override
                    public String[] load(String queryKey) throws Exception {
                        return getDataByKey(queryKey);
                    }
                });

but when I try to get CacheStat object ( by call toString method )

dataCache.stats().toString();

always retrieved this:

CacheStats{hitCount=0, missCount=0, loadSuccessCount=0,loadExceptionCount=0,totalLoadTime=0, evictionCount=0}

This is because you did not call #recordStats() on the CacheBuilder. By default gathering of statistics is disabled. (In which case the EMPTY_STATS object is returned.)
