saleson opened a new issue, #10012:
URL: https://github.com/apache/dubbo/issues/10012
### Environment
* Dubbo version: 3.5
* Java version: 1.8
出现该问题的代码：
``` java
private static ReferenceCache refCache = SimpleReferenceCache.getCache();
public static GenericService getService(String serviceName, String version){
ReferenceConfig<GeniricService> refConf = new ReferenceConfig();
refConf.setProtocol("zookeeper");
refConf.setAddress(registryAddress);
refConf.setRegistry(registryConfig);
refConf.setGeneric("true");
refConf.setInterface(serviceName);
refConf.setVersion(version);
refConf.setTimeout(5000);
return refCache.get(refConf);
}
```
### Expected Behavior
从缓存中获取GenericService
### Actual Behavior
<!-- What actually happens? -->
SimpleReferenceCache.get()方法没有从缓存中获取，而是直接调用了ReferenceConfig.get()，且执行了ReferenceConfig.init()另外创建了新的GenericService，
在zookeeper上也在相应的service节点下添加了consumer节点
SimpleReferenceCache.get(ReferenceConfigBase)：
```
public <T> T get(ReferenceConfigBase<T> rc) {
String key = generator.generateKey(rc);
Class<?> type = rc.getInterfaceClass();
Object proxy = rc.get();
references.computeIfAbsent(rc, _rc -> {
List<ReferenceConfigBase<?>> referencesOfType =
referenceTypeMap.computeIfAbsent(type, _t -> Collections.synchronizedList(new
ArrayList<>()));
referencesOfType.add(rc);
List<ReferenceConfigBase<?>> referenceConfigList =
referenceKeyMap.computeIfAbsent(key, _k -> Collections.synchronizedList(new
ArrayList<>()));
referenceConfigList.add(rc);
return proxy;
});
return (T) proxy;
}
```
如果使用DubboBootstrap.getInstance().getCache().get(refConf);也会出现一样的情况，DubboBootstrap.getInstance().getCache()返回的是CompositeReferenceCache对象，而CompositeReferenceCache.get(ReferenceConfigBase)方法如下：
```
public <T> T get(ReferenceConfigBase<T> referenceConfig) {
return referenceConfig.get();
}
```
可以看出，在CompositeReferenceCache.get(ReferenceConfigBase)方法和SimpleReferenceCache.get(ReferenceConfigBase)方法中都没有使用到缓存。
