private final LoadingCache<> cache = CacheBuilder.newBuilder()                  
                                                                      
.maximumWeight(maxCount)                                                        
                                
.weigher( (string, referenceConfig) -> getSize())                               
                                                         
.build();

private int getSize() {      
return (int) cache.size();
}
------------------------------------------------------------------------------------------------

Here, weight is used to control the total capacity of guava cache, but the 
weight of each cache use getSize,it represents the total number of items cached 
when a piece of data is cached.
I think there may be wrong usage here, If we use weights, the weights should 
represent the size of each piece of data, so here should be replaced by the 
number of bars to control the total capacity
