dubbo中关于protocol的配置

dubbo中关于protocol的配置

protocol 一个项目中可以配置多个，如果未定义port默认为20880（本人因为从网上copy了一个

<dubbo:protocol accesslog="true"/>，而且已定义<dubbo:protocol name="dubbo" port="20880" />,当我启动项目的多个实例时只修改了定义端口的protocol，而默认的未被修改，其他dubbo服务就会报端口已被占用程序退出的异常）

错误代码片段：

<?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/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

<dubbo:application name="demo-provider" />

<dubbo:registry address="zookeeper://localhost:2181"/>

<!-- 用dubbo协议在20880端口暴露服务 -->

<dubbo:protocol name="dubbo" port="20880" />

<dubbo:protocol accesslog="true" />

<dubbo:service interface="com.ssyt.dubbo.demo.DemoService" ref="demoService"/>

<bean id="demoService" class="com.ssyt.dubbo.dome.provider.DemoServiceImpl"/>

</beans>

红色部分为冲突代码，可改为不同的端口，一个项目中一种协议最好只定义一次

修改后的代码为：

<?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/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">

<dubbo:application name="demo-provider" />

<dubbo:registry address="zookeeper://localhost:2181"/>

<!-- 用dubbo协议在20880端口暴露服务 -->

<dubbo:protocol name="dubbo" port="20880" accesslog="true"/>

<dubbo:service interface="com.ssyt.dubbo.demo.DemoService" ref="demoService"/>

<bean id="demoService" class="com.ssyt.dubbo.dome.provider.DemoServiceImpl"/>

</beans>
