> Dubbo -> proxy -> cache
**使用这种方式是可以的
把@Cacheable 放到@DubboService但是就失去了缓存的意义了， 需要走一次RPC调用， 这个过程比较耗时。
想把cache放在interface， 消费端引用interface， 直接在消费端走缓存减少RPC的调用耗时**
```
@DubboService(interfaceClass = FileExposeService.class)
public class FileExposeServiceImpl implements FileExposeService {
@Override
@Cacheable(value = FileDefinition.CACHE_KEY_URL_MULTIPLE,key = "#tableId
+ '-' + #fileFieldName + '-' +#tableName")
public Map<Long, String> getUrl(Long tableId, String
fileFieldName,String tableName) {
…………
return urls;
}
@Override
@Cacheable(value = FileDefinition.CACHE_KEY_URL_MULTIPLE,key = "#tableId
+ '-' + #fileFieldName + '-' +#tableName")
public String getUrlSingle(Long tableId, String fileFieldName, String
tableName) {
…………
return "";
}
```
