多协议
在 Dubbo 中配置多协议
此文档已经不再维护。您当前查看的是快照版本。如果想要查看最新版本的文档，请参阅最新版本。
Dubbo 允许配置多协议，在不同服务上支持不同协议或者同一服务上同时支持多种协议。
不同服务不同协议
不同服务在性能上适用不同协议进行传输，比如大数据用短连接协议，小数据大并发用长连接协议

<dubbo:registry id="registry" address="10.20.141.150:9090" username="admin" password="hello1234" />
<!-- 多协议配置 -->
<dubbo:protocol name="dubbo" port="20880" />
<dubbo:protocol name="rmi" port="1099" />
<!-- 使用dubbo协议暴露服务 -->
<dubbo:service interface="com.alibaba.hello.api.HelloService" version="1.0.0" ref="helloService" protocol="dubbo" />
<!-- 使用rmi协议暴露服务 -->
<dubbo:service interface="com.alibaba.hello.api.DemoService" version="1.0.0" ref="demoService" protocol="rmi" />
</beans>
多协议暴露服务
需要与 http 客户端相互操作

<!-- 使用多个协议暴露服务 -->
<dubbo:service id="helloService" interface="com.alibaba.hello.api.HelloService" version="1.0.0" protocol="dubbo,hessian" />
