+### 特性说明
+
+Dubbo 自 2.7.5 版本开始支持 RocketMQ 协议。RocketMQ协议是基于RocketMQ-功能进行通信，适合需要通信信息记录或则金融场景。
+
+1.
[RokcetMQ基本兼容dubbo的原生dubbo协议与序列化协议[请点击]](https://dubbo.apache.org/zh/docs3-v2/java-sdk/reference-manual/protocol/dubbo/)
+2.
[RocketMQ官方安装教程[请点击]](https://rocketmq.apache.org/zh/docs/quickStart/02quickstart)
+
+### 协议配置
+最简单配置
+```
+dubbo.registry.address=nameservice://{nameservice-address}
+dubbo.protocol.name=rocketmq
+```
+#### 配置注册中心
+
+因为RocketMQ的borker元数据都由RocketMQ管理组件name-service负责，所以RocketMQ协议的注册中心只能使用name-service
+因自动创建topic方式，在分布式集群下可能有问题，所以有自动创建topic与手动创建配置两种模式
+```
+dubbo.registry.address=nameservice://localhost:9876
+dubbo.registry.parameters.route=true // 默认为true，自动创建topic，如果手动创建请设为false
+```
+
+
+#### Topic的命令规则以及分组细节
+
+topic创建规则有两种,
+
+- topic模式：就是以topic区别version与group
+ - topic命名规则是："providers-{serviceName}-{version}-{group}-{CRC32}"
+- select模式：使用RocketMQ的MessageSelector来区别version与group
+ - topic命名规则是："providers-{serviceName}-{CRC32}"
+ - 注意：需要RocketMQ4.9.2以上版本才支持select模式
+
+| 字段 | 说明 |
+| --- | --- |
+| serviceName | 接口名 |
+| version | 版本号 |
+| group | 分组名 |
+| CRC32 | providers-{serviceName}-{version}-{group}或则providers-{serviceName}
的校验码，是用于防止在复杂情况下topic重复的问题 |
+
+
+```
+dubbo.protocol.parameters.groupModel=topic // topic 是第一种模式，参数为select 为第二种模式。
+```
+
+#### RocketMQ-Client配置
+生产端配置
+```
+dubbo.provider.parameters.enableMsgTrace=topic //Switch flag instance for
message trace
+dubbo.provider.parameters.namespace=topic //Namespace for this MQ Producer
instance
+dubbo.provider.parameters.customizedTraceTopic=topic //The name value of
message trace topic.If you don't config,you can use the default trace topic name
+```
+消费端配置
+```
+dubbo.consumer.parameters.enableMsgTrace=topic //Switch flag instance for
message trace
+dubbo.consumer.parameters.namespace=topic //Namespace for this MQ Producer
instance
+dubbo.consumer.parameters.customizedTraceTopic=topic //The name value of
message trace topic.If you don't config,you can use the default trace topic name
+```
