Springboot改造之配置--Dubbo配置篇

接上一篇，api模块很简单，就是对外提供接口，所以就不做介绍了，下面讲一下Sprintboot 中对dubbo的配置。  
  
dubbo的配置在 core 模块，首先来看一下在项目中的位置：  
![这里写图片描述][70]

左侧选中的三行就是dubbo主要的配置，resources下是 dubbo-provider.xml 和 dubbo-consumer.xml ， 用于提供服务、引用服务，文件的内容如下：  
  
dubbo-provider.xml

<?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="msso-provider" owner="acs-provider" organization="Msso-Center" />
        <dubbo:registry address="${registry-address}" protocol="zookeeper" />
        <dubbo:protocol name="dubbo" port="${provider-port}" accesslog="true" />
    
        <dubbo:service ref="outInSettleFacade" group="${msso-service-group}" version="${msso-service-version}" timeout="${msso-service-timeout}" interface="com.mljr.acs.boss.settle.service.IOutInSettleFacade" cluster="failfast" />
    
    
    </beans>

dubbo-consumer.xml

<?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:registry address="${consumer-registry-address}" protocol="zookeeper"/>
    
        <dubbo:reference id="queryFacade" interface="com.mljr.order.service.QueryFacade" cluster="failfast" group="${acs-settle-service-group}" version="${acs-settle-service-version}" check="false" timeout="${acs-settle-service-timeout}">
        </dubbo:reference>
    </beans>

下面是令dubbo配置生效的注解配置：

package com.mljr.auth.config;
    
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.ImportResource;
    import org.springframework.context.annotation.PropertySource;
    
    @Configuration
    @PropertySource("classpath:dubbo-consumer.properties")
    @PropertySource("classpath:dubbo-provider.properties")
    @ImportResource({ "classpath:/dubbo/dubbo-*.xml" })
    public class DubboConfig {
    }

@Configuration注解 是令注解的类中的配置生效  
@PropertySource注解 是引入属性配置文件properties，使其中配置的属性变成应用全局变量而被引用  
@ImportResource注解 实现xml配置的装载，使应用启动时自动装载文件中的配置

最后讲一下属性配置文件，配置文件在web模块，目前只配置了dev 和 prod 环境，以 dev 为例  
![这里写图片描述][70 1]

dubbo-provider.properties

registry-address=192.168.xx.xxx:2181
    provider-port=24461
    
    msso-service-group=MssoCenter-dev
    msso-service-version=1.0.0
    msso-service-timeout=3000000

dubbo-consumer.properties

consumer-registry-address=192.168.xx.xxx:2181
    fault-tolerance-type=failfast
    
    acs-settle-service-group=ACS-SettleCenter-dev
    acs-settle-service-version=1.0.0
    acs-settle-service-timeout=300000

properties中配置的属性，对应着xml文件中 \{ \} 内的变量引用。Dubbo配置的说明就到这里。
