这篇文章总结结构上的服务提供方，消费方demo，用于学习交流：
1.打开idea，新建一个项目，这里要用到聚合项目搭建，首先新建一个maven或者SpringBoot项目的外壳，
结构层次是：
<modules>
<module>house-api</module>
<module>house-provider</module>
<module>house-consumer</module>
</modules>
创建好maven聚合项目的外壳goss-house后，检查goss-house的pom文件，然后创建子项目，如图：
2.创建定义接口的项目，house-api，这个项目是接口的定义，创建为常规的maven项目，在后面的house-provider,house-consumer需要依赖到，
<groupId>com.yyds.house</groupId> <artifactId>house-api</artifactId> <version>0.0.1-SNAPSHOT</version>
3.house-provider 项目的模块项目创建成SpringBoot项目，这里要注意好各个模块项目的结构，包目录定义
创建好house-provider项目后，管理pom文件，增加项目说明，版本号定义，添加spring-boot关联dubbo的依赖：
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.yyds.house</groupId>
<artifactId>house-provider</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>house-provider</name>
<description>Demo project for Spring Boot</description>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>io.dubbo.springboot</groupId>
<artifactId>spring-boot-starter-dubbo</artifactId>

</dependency>
<dependency>
<groupId>com.yyds.house</groupId>
<artifactId>house-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>

<exclusion>

</exclusions>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.9.8</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
4.house-consumer的模块项目，也是创建成为SpringBoot项目，创建完成给house-consumer增加项目说明，版本号定义，用于编译打包的本地仓库；
<groupId>com.yyds.house</groupId> <artifactId>house-consumer</artifactId> <version>0.0.1-SNAPSHOT</version>
house-consumer的pom文件如下：
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.yyds.house</groupId>
<artifactId>house-consumer</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>house-consumer</name>
<description>Demo project for Spring Boot</description>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>io.dubbo.springboot</groupId>
<artifactId>spring-boot-starter-dubbo</artifactId>
<version>1.0.0</version>
</dependency>
<dependency>
<groupId>com.yyds.house</groupId>
<artifactId>house-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
5.在house-provider的application.properties文件中添加dubbo的配置：
server.port=7004 spring.dubbo.application.name=house-provider spring.dubbo.registry.address=zookeeper://127.0.0.1:2181 spring.dubbo.protocol.name=dubbo spring.dubbo.protocol.port=20880 #spring.dubbo.scan=com.yyds.house.service spring.dubbo.scan=com.yyds.house.houseprovider
6.在house-consumer的application.properties文件中添加dubbo的配置：
server.port=7003 #dubbo config spring.dubbo.application.name=house-consumer spring.dubbo.registry.address=zookeeper://127.0.0.1:2181 spring.dubbo.scan=com.yyds.house.consumer
7.在house-api项目中，分别定义 AddressInfoApi, HouseInfoApi , house-provider依赖 house-api，实现具体的业务， house-consumer 依赖 house-provider 进行消费调用；
8.各个模块编译代码完成：
1-编译 install house-api，
2-house-provider刷新maven依赖，house-consumer刷新maven依赖；
3-启动house-provider
4-启动house-consumer, 根据端口号，地址访问消费；http://localhost:7003/qHouse?houseNo=9098
地址服务消费：
9.在dubb-admin 可以查看到对应服务发布信息：
注意：
1-先启动zookeeper服务
2-启动提供方 house-provider
3-启动消费方 house-consumer
4-进行服务调用
5-启动dubb-admin监控服务，查看提供方，消费方的服务情况
