一.  dubbo-admin管理控制台

  1. 从 https://github.com/apache/dubbo-admin clone项目到本地。
  2. 修改dubbo-admin-server中的application.properties改为自己的zookeeper地址
  3. 执行 mvn clean package -Dmaven.test.skip=true
  4. 找到刚才打包的jar文件，java -jar dubbo-admin-server-0.1.jar
  5. 浏览器输入 http://localhost:8080即可进入dubbo-admin 界面，如下图所示。

二、

https://blog.csdn.net/qq_25215821/article/details/100806580

这里有配置服务提供者。

1. 新建一个maven项目：hello-dubbo-service-user-api

pom.xml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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <modelVersion>4.0.0</modelVersion>

    <groupId>com.funtl</groupId>

    <artifactId>hello-dubbo-service-user-api</artifactId>

    <version>1.0.0-SNAPSHOT</version>

    <packaging>jar</packaging>

    <properties>

        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

        <java.version>1.8</java.version>

    </properties>

</project>

创建一个接口UserService.java ：
package com.funtl.hello.dubbo.service.user.provider.api;

public interface UserService {

    String sayHi();

}

2. 再创建一个服务提供者项目 hello.dubbo.service.user.provider

pom.xml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>2.2.1.RELEASE</version>

      <relativePath/> <!-- lookup parent from repository -->

   </parent>

   <groupId>com.funtl</groupId>

   <artifactId>hello-dubbo-service-user-provider</artifactId>

   <version>1.0.0-SNAPSHOT</version>

   <name>hello-dubbo-service-user-provider</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</artifactId>

      </dependency>

      <dependency>

         <groupId>org.springframework.boot</groupId>

         <artifactId>spring-boot-starter-actuator</artifactId>

      </dependency>

        <dependency>

            <groupId>com.alibaba.boot</groupId>

            <artifactId>dubbo-spring-boot-starter</artifactId>

            <version>0.2.0</version>

        </dependency>

      <dependency>

         <groupId>com.funtl</groupId>

         <artifactId>hello-dubbo-service-user-api</artifactId>

         <version>1.0.0-SNAPSHOT</version>

      </dependency>

      <dependency>

         <groupId>org.springframework.boot</groupId>

         <artifactId>spring-boot-starter-test</artifactId>

         <scope>test</scope>

         <exclusions>

            <exclusion>

               <groupId>org.junit.vintage</groupId>

               <artifactId>junit-vintage-engine</artifactId>

            </exclusion>

         </exclusions>

      </dependency>

   </dependencies>

   <build>

      <plugins>

         <plugin>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-maven-plugin</artifactId>

         </plugin>

      </plugins>

   </build>

</project>

这里依赖了上一个项目的jar包，利用了maven的依赖机制，所以先要把上一个项目 mvn clean install到本地仓库。

然后创建一个类实现刚才创建的接口

UserServiceImpl.java
注意：包名和上一个接口项目保持一致，这样打包会打在一起，方便。

package com.funtl.hello.dubbo.service.user.provider.api.impl;

import com.alibaba.dubbo.config.annotation.Service;

import com.funtl.hello.dubbo.service.user.provider.api.UserService;

@Service(version = "${user.service.version}")

public class UserServiceImpl implements UserService{

    @Override

    public String sayHi() {

        return "hello dubbo...";

    }

}
最后需要在项目程序入口类里面增加代码
package com.funtl.hello.dubbo.service.user.provider;

import com.alibaba.dubbo.container.Main;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication

public class HelloDubboServiceUserProviderApplication {

   public static void main(String[] args) {

      SpringApplication.run(HelloDubboServiceUserProviderApplication.class, args);

      Main.main(args);

   }

}

application.yml配置如下：（yml格式注意空格）

spring:

  application:

    name: hello-dubbo-service-user-provider

user:

  service:

    version: 1.0.0

dubbo:

  scan:

    basePackages: com.funtl.hello.dubbo.service.user.provider.api

  application:

    id: hello-dubbo-service-user-provider

    name: hello-dubbo-service-user-provider

    qos-port: 22222

    qos-enable: true

  protocol:

    id: dubbo

    name: dubbo

    port: 12345

    status: server

  registry:

    id: zookeeper

    address: zookeeper://10.1.10.19:2181?backup=10.1.10.19:2182,10.1.10.19:2183

management:

  endpoint:

    dubbo:

      enabled: true

    dubbo-shutdown:

      enabled: true

    dubbo-configs:

      enabled: true

    dubbo-services:

      enabled: true

    dubbo-references:

      enabled: true

    dubbo-properties:

      enabled: true

  health:

    dubbo:

      status:

        defaults: memory

        extras: load,threadpool



最后启动项目刷新http://localhost:8080





上图显示服务已经注册到zookeeper上了。服务提供者完成。


三、服务消费者


创建一个springboot web项目 hello.dubbo.service.user.consumer


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 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>2.2.1.RELEASE</version>

        <relativePath/> <!-- lookup parent from repository -->

    </parent>

    <groupId>com.funtl</groupId>

    <artifactId>hello-dubbo-service-user-consumer</artifactId>

    <version>0.0.1-SNAPSHOT</version>

    <name>hello-dubbo-service-user-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>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-actuator</artifactId>

        </dependency>

        <dependency>

            <groupId>com.alibaba.boot</groupId>

            <artifactId>dubbo-spring-boot-starter</artifactId>

            <version>0.2.0</version>

        </dependency>

        <dependency>

            <groupId>com.funtl</groupId>

            <artifactId>hello-dubbo-service-user-api</artifactId>

            <version>1.0.0-SNAPSHOT</version>

        </dependency>

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-test</artifactId>

            <scope>test</scope>

            <exclusions>

                <exclusion>

                    <groupId>org.junit.vintage</groupId>

                    <artifactId>junit-vintage-engine</artifactId>

                </exclusion>

            </exclusions>

        </dependency>

    </dependencies>

    <build>

        <plugins>

            <plugin>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-maven-plugin</artifactId>

            </plugin>

        </plugins>

    </build>

</project>




创建UserController 类：




package com.funtl.hello.dubbo.service.user.consumer.controller;

import com.alibaba.dubbo.config.annotation.Reference;

import com.funtl.hello.dubbo.service.user.provider.api.UserService;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

@RestController

public class UserController {

    @Reference(version="${user.service.version}")

    private UserService userService;

    @RequestMapping(value = "hi",method = RequestMethod.GET)

    public String sayHi(){

        return userService.sayHi();

    }

}




application.yml:




spring:

  application:

    name: hello-dubbo-service-user-consumer

user:

  service:

    version: 1.0.0

dubbo:

  scan:

    basePackages: com.funtl.hello.dubbo.service.user.consumer.controller

  application:

    id: hello-dubbo-service-user-consumer

    name: hello-dubbo-service-user-consumer

    qos-port: 22223

    qos-enable: true

  protocol:

    id: dubbo

    name: dubbo

    port: 12345

    status: server

  registry:

    id: zookeeper

    address: zookeeper://10.1.10.19:2181?backup=10.1.10.19:2182,10.1.10.19:2183

management:

  endpoint:

    dubbo:

      enabled: true

    dubbo-shutdown:

      enabled: true

    dubbo-configs:

      enabled: true

    dubbo-services:

      enabled: true

    dubbo-references:

      enabled: true

    dubbo-properties:

      enabled: true

  health:

    dubbo:

      status:

        defaults: memory

        extras: load,threadpool

server:

  port: 9090




浏览器访问：http://localhost:9090/hi，显示如下：




完成调用！！！


dubbo-admin显示有消费者：




完成@！！


谢谢参考。
