1.使用版本

jdk1.8、springboot2.0.0、Dubbo2.7.3、zookeeper3.6.0、curator4.2.0。

Dubbo2.7.3是Apache上的項目，而不是alibaba上的項目（使用註解的時候請使用apache的，alibaba的會顯示過時）。

2.項目結構

組件名稱	工程	備註
註冊中心	zookeeper3.6.0安裝
服務api	dubbo-interf
服務提供方	dubbo-provider
服務消費方	dubbo-consumer

 

 

 

 

3.創建父工程

pom：

<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>
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.0.RELEASE</version>
		<relativePath /> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.zyf</groupId>
	<artifactId>dubbo-parent</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>pom</packaging>
	<name>dubbo-parent</name>
	<description>dubbo微服務父工程</description>
	<modules><!-- dubbo微服務子工程 -->
		<module>dubbo-provider</module>
		<module>dubbo-consumer</module>
		<module>dubbo-interf</module>
	</modules>
</project>

4.創建服務api工程

pom：

普通的springboot工程，定義一個接口，無配置。可單獨打包，接口能被提供者和消費者引用。

<?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><!-- 父工程座標 -->

		<version>0.0.1-SNAPSHOT</version>
	</parent>
	<artifactId>dubbo-interf</artifactId>
	<name>dubbo-interf</name>
	<description>dubbo微服務接口工程</description>
	<properties>
		<java.version>1.8</java.version>
	</properties>
	<dependencies>

			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

接口：

package com.zyf.dubbointerf.service;
/**
 * 定義dubbo api，單獨打包，被提供者和消費者共通引用
 */
public interface ApiService {
	public String sayHello(String name);
}

5.創建服務提供者工程

5.1.pom依賴

<?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><!-- 父工程座標 -->
		<groupId>com.zyf</groupId>
		<artifactId>dubbo-parent</artifactId>
		<version>0.0.1-SNAPSHOT</version>
	</parent>
	<artifactId>dubbo-provider</artifactId>
	<name>dubbo-provider</name>
	<description>Ddubbo微服務提供者</description>
	<properties>
		<java.version>1.8</java.version>
	</properties>
	<dependencies>

		</dependency>
		<dependency>

			<artifactId>spring-boot-starter</artifactId>
		</dependency>
		<dependency><!-- 引入父工程下服務api工程 -->
			<groupId>${project.groupId}</groupId>
			<artifactId>dubbo-interf</artifactId>
			<version>${project.version}</version>
		</dependency>
		<!-- 集成dubbo所需依賴 start -->
		<dependency>

		</dependency>
		<dependency>

		</dependency>
		<dependency>
			<groupId>org.apache.curator</groupId>
			<artifactId>curator-recipes</artifactId>
			<version>4.2.0</version>
		</dependency>
		<!-- 集成dubbo所需依賴 end -->
	</dependencies>
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

5.2.application.yml配置註冊中心

server:
  port: 8001 #服務端口
dubbo:
  application:
    name: provider #應用名
  registry:
    address: 127.0.0.1:2181 # zookeeper地址和端口
    protocol: zookeeper
    check: false
  protocol:
    name: dubbo
    port: 30003
  monitor:
    protocol: register
  consumer:
    check: false
    timeout: 3000

5.3.dubbo功能開啓

@EnableDubbo開啓apache dubbo

package com.zyf.dubboprovider;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableDubbo // 開啓apache dubbo
public class DubboProviderApplication {
	public static void main(String[] args) {
		SpringApplication.run(DubboProviderApplication.class, args);
	}
}

5.4.服務api實現

@Service是apache dubbo的servcie註解

package com.zyf.dubboprovider.service;

import org.apache.dubbo.config.annotation.Service;
import com.zyf.dubbointerf.service.ApiService;

@Service // apache dubbo的servcie註解
public class ApiServiceImpl implements ApiService {
	@Override
	public String sayHello(String name) {
		System.out.println("來自服務提供者的問候：hello " + name);
		return "來自服務提供者的問候：hello " + name;
	}
}

6.創建服務消費者工程

6.1.pom依賴

與服務提供者的依賴一致。

<?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><!-- 父工程座標 -->
		<groupId>com.zyf</groupId>
		<artifactId>dubbo-parent</artifactId>
		<version>0.0.1-SNAPSHOT</version>
	</parent>
	<artifactId>dubbo-consumer</artifactId>
	<name>dubbo-consumer</name>
	<description>Ddubbo微服務消費者</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</artifactId>
		</dependency>
		<dependency><!-- 引入父工程下服務api工程 -->
			<groupId>${project.groupId}</groupId>
			<artifactId>dubbo-interf</artifactId>
			<version>${project.version}</version>
		</dependency>
		<!-- 集成dubbo所需依賴 start -->
		<dependency>
			<groupId>org.apache.dubbo</groupId>
			<artifactId>dubbo-spring-boot-starter</artifactId>
			<version>2.7.3</version>
		</dependency>
		<dependency>
			<groupId>org.apache.curator</groupId>
			<artifactId>curator-framework</artifactId>
			<version>4.2.0</version>
		</dependency>
		<dependency>
			<groupId>org.apache.curator</groupId>
			<artifactId>curator-recipes</artifactId>
			<version>4.2.0</version>
		</dependency>
		<!-- 集成dubbo所需依賴 end -->
	</dependencies>
	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>
</project>

6.2.application.yml配置註冊中心

server:
  port: 9001 #服務端口
dubbo:
  application:
    name:  consumer #應用名
  registry:
    address: 127.0.0.1:2181 #zookeeper地址和端口
    protocol: zookeeper
    check: false
  monitor:
    protocol: register
  consumer:
    check:  false
    timeout: 3000 

6.3.dubbo功能開啓

package com.zyf.dubboconsumer;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableDubbo // 開啓apache dubbo
public class DubboConsumerApplication {
	public static void main(String[] args) {
		SpringApplication.run(DubboConsumerApplication.class, args);
	}
}

6.4.調用服務api

@Service是spring的servcie註解。

@Reference是apache dubbo的註解，注入服務接口實例。

package com.zyf.dubboconsumer.service;

import org.apache.dubbo.config.annotation.Reference;
import org.springframework.stereotype.Service;
import com.zyf.dubbointerf.service.ApiService;

@Service // spring的servcie註解
public class ConsumerService {
	@Reference // apache dubbo的@Reference註解，注入服務接口實例
	private ApiService apiService;
	public String sayHello(String name) {
		return apiService.sayHello(name);
	}
}

6.5.測試

package com.zyf.dubboconsumer.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.zyf.dubboconsumer.service.ConsumerService;

@RestController
@RequestMapping("/ConsumerController")
public class ConsumerController {
	@Autowired
	ConsumerService consumerService;
	@RequestMapping("/sayHello")
	public String sayHello(String name) {
		return consumerService.sayHello(name);
	}
}

訪問：http://localhost:9001/ConsumerController/sayHello?name=zhangsan

成功！

--------------------------------------------------------

另外可以通過dubb admin控制檯查看是否註冊成功：

可以看到提供者和消費者的應用名。
