 #### HttpAdapter
 在serving-server.properties文件中配置属性feature.single.adaptor和http.adapter.url，feature.single.adaptor为继承AbstractSingleFeatureDataAdaptor
-接口，url为调用获取数据接口地址。
-feature.single.adaptor=com..webank.ai.fate.serving.adaptor.dataaccess.HttpAdapter
+接口，url为调用获取数据接口地址。  
+```yaml
+feature.single.adaptor=com.webank.ai.fate.serving.adaptor.dataaccess.HttpAdapter
 http.adapter.url=http://127.0.0.1:9380/v1/http/adapter/getFeature
