带功能隔离的 cache 设计

@Service
public class CacheFactory {
	
  //由spring自动注入
  private Map<String, CacheService> cacheServiceMap;
  @Autowired
  public CacheFactory(Map<String, CacheService> cacheServiceMap) {
    this.cacheServiceMap = cacheServiceMap;
  }
  
  CacheService getCacheService(){
    //由rebuild服务更新
    String type=CacheConfig.getCacheType();
    return cacheServiceMap.get(type);
  }
}
