SpringBoot+Zookeeper+Dubbo整合（二）

    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>
      <version>1.0.0</version>
    </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>
      <exclusions>
        <exclusion>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-annotations</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
