關於maven+dubbo+springboot環境的搭建

大概流程是這樣的：

項目A有一個接口Ainterface，想一個接口實現類Aimpl；

項目B要用到Aimpl，但是通過dubbo和maven，可以在只知道接口的情況下實現。

A需要將接口上傳到maven私服，通過zookeeper註冊實現類。

B導入maven的接口類之後，通過註冊zookeeper可以調用Aimpl。

具體代碼如下：

A項目的接口

public interface TestDubbo {
    String testDubbo(String s);
}

A的實現類：

public class TestDubboImpl implements TestDubbo {
    @Override
    public String testDubbo(String s) {
        System.out.println("ssss");
        return s+"-------"+s;
    }
}

A的pom.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <artifactId>facade</artifactId>
    <groupId>com.example.provider</groupId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>



    <distributionManagement>
        <repository>
            <id>weidai-releases</id>
            <url>http://ip:port/nexus/content/repositories/releases</url>
        </repository>
        <snapshotRepository>
            <id>weidai-snapshots</id>
            <url>http://ip:port/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
    </distributionManagement>

</project>

A的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">
    <!--提供方應用信息，用於計算依賴關係-->
    <dubbo:application name="demo-provider" />
    <!--使用zookeeper註冊中心暴露服務地址-->
    <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" />
    <!--用dubbo協議在20880端口暴露服務-->
    <dubbo:protocol name="dubbo" port="20880" />
    <!--自己的測試服務-->
    <dubbo:service interface="com.facade.TestDubbo" ref="TestDubboImpl"/>
    <bean id="TestDubboImpl" class="server.TestDubboImpl" />


</beans>

B的maven   pom.xml配置：
