+<p>Dubbo
通过协议扩展实现了很多内置的功能，同时也支持很多常用的协议。所有的自定义协议在<code>org.apache.dubbo.rpc.Protocol</code>文件中可以看到，以Dubbo
3为例，具体如下：</p>

+<p>自定义一套私有协议有两种方式，第一种是对原有的协议进行包装，添加一些特定的业务逻辑。另外一种是完全自定义一套协议。前者实现简单，在<code>dubbo</code>中也是有广泛的使用，比如：<code>ProtocolFilterWrapper</code>,
<code>QosProtocolWrapper</code>,
<code>ProtocolListenerWrapper</code>等。后者实现复杂，一般常见的协议<code>dubbo</code>都实现了，并且通过了大量生产实践的验证。</p>
+<p>本文会通过示例演示如何通过现有协议实现一套自定义协议。</p>
