Dubbo中多协议

时间:2023-06-12 13:57:14

  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

1.不同服务不同协议配置

  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

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
     xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://code.alibabatech.com/schema/dubbohttp://code.alibabatech.com/schema/dubbo/dubbo.xsd">
     <dubbo:application name="world"  />
     <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>

2.同一服务上同时支持多种协议

  需要与 http 客户端互操作

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
     xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://code.alibabatech.com/schema/dubbohttp://code.alibabatech.com/schema/dubbo/dubbo.xsd">
     <dubbo:application name="world"  />
     <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="hessian" port="8080" />
     <!-- 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" />
 </beans>
