1、安装好zookeeper并启动

2、创建服务提供方项目------》dubbo01-provider

2.1、引入pom依赖

<properties>
    <java.version>1.8</java.version>
    <dubbo.version>2.7.1</dubbo.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-devtools</artifactId>
        <scope>runtime</scope>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    <!-- Aapche Dubbo -->

    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo-spring-boot-starter</artifactId>
        <version>${dubbo.version}</version>
    </dependency>

    <dependency>
        <groupId>org.apache.dubbo</groupId>
        <artifactId>dubbo</artifactId>
        <version>${dubbo.version}</version>
    </dependency>

    <!--  分页插件 https://mvnrepository.com/artifact/com.github.pagehelper/pagehelper-spring-boot-starter -->
    <dependency>
        <groupId>com.github.pagehelper</groupId>
        <artifactId>pagehelper-spring-boot-starter</artifactId>
        <version>1.2.12</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.curator/curator-framework -->
    <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>
        <exclusions>
            <exclusion>
                <groupId>org.apache.zookeeper</groupId>
                <artifactId>zookeeper</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>org.apache.zookeeper</groupId>
        <artifactId>zookeeper</artifactId>
        <version>3.4.14</version>
    </dependency>
</dependencies>

2.2、创建service和实现类

package com.mashibing.db1.service;

/**
 * 描述
 *
 * @author 关
 * @version 1.0
 * @date 2021/07/19 11:43:09
 */
public interface DemoService {
    String sayHello(String name);
}

import org.springframework.stereotype.Component;

/**
 * 描述
 *
 * @author 关
 * @version 1.0
 * @date 2021/07/19 11:43:43
 */
@Service(version = "1.0.0",timeout = 1000,interfaceClass = DemoService.class)
@Component
public class DemoServiceImp implements DemoService{
    @Override
    public String sayHello(String name) {
        System.out.println(name+"说:hello");
        return name+"hello";
    }
}

2.3、创建配置文件

server:
  port: 8081
spring:
  application:
    name: DemoProvider
dubbo:
  scan:
    base-packages: com.mashibing.db1.service
  protocol:
    name: dubbo
    port: 28081
    host: 192.168.253.44
  registry:
    address: zookeeper://192.168.174.129:2181

2.4、记得在启动类上添加@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

package com.mashibing;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;

/**
 * @author grey
 */
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class Dubbo01ProviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(Dubbo01ProviderApplication.class, args);
    }

}

3、创建消费者项目------》dubbo01-customer

3.1、创建application.properties配置文件

spring.application.name=DemoCustomer
dubbo.scan.base-packages=com.msb.db1.service

dubbo.registry.address=zookeeper://192.168.174.129:2181

3.2、创建需要调用的服务

package com.mashibing.db1.service;

public interface DemoService {

    String sayHello(String name);

}

3.3、在当前模块进行调用

package com.mashibing.db1.service;

import org.apache.dubbo.config.annotation.Reference;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 描述
 *
 * @author 关
 * @version 1.0
 * @date 2021/07/19 12:51:16
 */
@RestController
@RequestMapping("/dubbo")
public class HelloController {
    @Reference(version = "1.0.0")
    DemoService demoService;

    @RequestMapping("/say")
    public String say(){
        System.out.println("say----");
        return demoService.sayHello("hello dubbo");
    }
}

3.4、切记在启动类上添加@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)注解
