There may be a wrong way to use guava cache

[ttttangzhen]

in org.apache.shenyu.plugin.apache.dubbo.cache.ApplicationConfigCache and
 ApplicationConfigCache in other RPC plugin
private final LoadingCache<String, ReferenceConfig<GenericService&gt;&gt; cache 
= CacheBuilder.newBuilder()             .maximumWeight(maxCount)             
.weigher((Weigher<String, ReferenceConfig<GenericService&gt;&gt;) (string, 
referenceConfig) -&gt; getSize())             .removalListener(notification 
-&gt; {                 // ignore...             })             .build(new 
CacheLoader<String, ReferenceConfig<GenericService&gt;&gt;() {                 
// ignore...             }); private int getSize() {     return (int) 
cache.size(); } 

Here, weight is used to control the total capacity of&nbsp;guava cache, but the 
weight of each cache use&nbsp;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
