dubbo 直连不经过注册中心

1.背景：现有springcloud项目已使用的注册中心，并不想再使用zk作为注册中心，内部不同集群（不在同一个注册中心的集群）直接的交互无法使用springcloud的feign 调用，直接发送Http不方便，最终决定使用Dubbo

2.springboot 集成dubbo，使用配置文件的方式

dubbo-customer.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="springboot-consumer"/>
    <!-- 集群下url可疑指定多个逗号分隔例如：dubbo://127.0.0.1:20880,dubbo://127.0.0.1:20881 -->
    <dubbo:reference id="testService" version="1.0.0"  interface="com.yyf.dubbo.inf.TestService" url="dubbo://127.0.0.1:20880"/>
</beans>

springboot 启动类上加上@ImportResource(value = {"classpath:dubbo-customer.xml"})

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="springboot-provider" />
    <dubbo:annotation package="com.yyf.dubbo.provider.service"></dubbo:annotation>
    <dubbo:protocol name="${dubbo.name}" port="${dubbo.port}"></dubbo:protocol>
    <!-- 弃用注册中心 -->
    <dubbo:registry address="N/A" />
    <dubbo:service  ref="testServiceImpl"  interface="com.yyf.dubbo.inf.TestService" version="1.0.0"></dubbo:service>
</beans>

<dubbo:registry address="N/A" /> 不使用注册中心时 registry address 一定要设置为N/A

@ImportResource(value = {"classpath:dubbo-provider.xml"})
