windows下搭建dubbo 环境（dubbo-admin和服务提供者消费者）

---恢复内容开始---

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。
