+## 关于扩展
+
+> 参与`dubbo`中的`SPI`
+>
+> > 所有具备`@SPI`注解的接口，可以在`resources/META-INF/gateway`中新建以接口名为文件名的文件进行扩展
+
+## 内置扩展
+
+> `cn.nosum.common.extension.ExtensionFactory`
+>
+> > 扩展点工厂类，默认使用`adaptive`
+
+```properties
+adaptive=cn.nosum.common.extension.factory.AdaptiveExtensionFactory
+spi=cn.nosum.common.extension.factory.SpiExtensionFactory
+```
+
+>`cn.nosum.gateway.container.GateWayContainer`
+>
+>> 网关容器，默认使用`netty`
+
+```properties
+netty=cn.nosum.gateway.container.NettyGateWayContainer
+```
+
+> `cn.nosum.gateway.handler.build.HandlerBuilder`
+>
+> > 容器`handler`构建器，默认使用`context`
+
+```properties
+context=cn.nosum.gateway.handler.build.ContextHandlerBuilder
+```
+
+> `cn.nosum.gateway.slot.build.SlotChainBuilder`
+>
+> > 处理槽构建器，默认使用`context`
+
+```properties
+context=cn.nosum.gateway.slot.build.LinkSlotChainBuilder
+```
+
+> `cn.nosum.gateway.slot.ProcessorSlotChain`
+>
+> > 处理槽链路类型，默认使用`link`
+
+```properties
+link=cn.nosum.gateway.slot.LinkProcessorSlotChain
+```
+
+## `application.properties`
+
+> 项目核心配置文件
+
+```properties
+# 容器端口号
+container.port = 8888
+request.file.save.folder.name = /usr/local/gateway/request/file
+# 示例配置，即使不配置也是默认使用这些
+cn.nosum.common.extension.ExtensionFactory = adaptive
+cn.nosum.gateway.container.GateWayContainer = netty
+cn.nosum.gateway.handler.build.HandlerBuilder = context
+cn.nosum.gateway.slot.build.SlotChainBuilder = context
+cn.nosum.gateway.slot.LinkProcessorSlotChain = link
+```
+
+## `GateWay `启动入口
+
+```java
+public class NoSumGateWayStart {
+    public static void main(String[] args) {
+        GateWayContainer container = ExtensionLoader
+                    .getExtensionLoader(GateWayContainer.class)
+                    .getAdaptiveExtension();
+        container.start();
+    }
+}
+```
+
+## 未实现的功能
+
+> 负载均衡、熔断、缓存、限流、鉴权

-/**
- * Marker for extension interface
- * <p/>
- * Changes on extension configuration file <br/>
- * Use <code>Protocol</code> as an example, its configuration file 'META-INF/dubbo/com.xxx.Protocol' is changes from: <br/>
- * <pre>
- *     com.foo.XxxProtocol
- *     com.foo.YyyProtocol
- * </pre>
- * <p>
- * to key-value pair <br/>
- * <pre>
- *     xxx=com.foo.XxxProtocol
- *     yyy=com.foo.YyyProtocol
- * </pre>
- * <br/>
- * The reason for this change is:
- * <p>
- * If there's third party library referenced by static field or by method in extension implementation, its class will
- * fail to initialize if the third party library doesn't exist. In this case, dubbo cannot figure out extension's id
- * therefore cannot be able to map the exception information with the extension, if the previous format is used.
- * <p/>
- * For example:
- * <p>
- * Fails to load Extension("mina"). When user configure to use mina, dubbo will complain the extension cannot be loaded,
- * instead of reporting which extract extension implementation fails and the extract reason.
- * </p>
- *
- * @deprecated because it's too general, switch to use {@link org.apache.dubbo.common.extension.SPI}
