    创建服务接口项目

    创建一个名为 TestDubboLogin 的项目，该项目只负责定义接口

    POM

    <?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.suoron</groupId>
    <artifactId>MyFirstDubbo</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <modules>
        <module>testdubbo-interface</module>
        <module>testdubbo-client</module>
        <module>testdubbo-server</module>
    </modules>
    <packaging>pom</packaging>

    <!-- 继承父包 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.2.RELEASE</version>
    </parent>

</project>

    创建3个模块(login-server、login-client、login-interface)

    定义服务接口 interface
    package com.suoron.dubbo.api.service;

/**
 *  用户相关接口
 */
public interface IUserService {
    public String login(String username,String password);
}

    创建服务提供者项目

    创建一个名为 login-server 的项目，该项目主要用于实现接口

    POM

    <?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"

        </plugins>
    </build>
</project>

    主要增加了以下依赖：

    • com.alibaba.boot:dubbo-spring-boot-starter:0.2.0：Dubbo Starter，0.2.0 版本支持 Spring Boot 2.x，是一个长期维护的版本。注：0.1.0 版本已经不推荐使用了，是个短期维护的版本，如果你还在用旧版，请大家尽快升级。
    • com.alibaba.boot:dubbo-spring-boot-actuator:0.2.0：Dubbo 的服务状态检查

    通过 @Service 注解实现服务提供方

    package com.suoron.dubbo.api.service.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.suoron.dubbo.api.service.IUserService;

@Service(version = "1.0.0")
public class UserServiceImpl implements IUserService {
    @Override
    public String login(String username, String password) {
        return "success";
    }
}

    Application

    package com.suoron.dubbo.server.app;

import com.alibaba.dubbo.container.Main;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableAutoConfiguration
@ComponentScan("com.suoron.dubbo.api.service")
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class,args);
        // 启动 Provider 容器，注意这里的 Main 是 com.alibaba.dubbo.container 包下的
        Main.main(args);
    }
}

    application.yml

    spring:
  application:
    name: login-provider

        extras: load,threadpool

logging:
  level:
    root: debug

    消费者项目login-client

    创建一个名为 login-client 的模块，该项目用于消费接口（调用接口）

    通过 @Reference 注入 IUserService 

    package com.suoron.dubbo.client.service.impl;

import com.alibaba.dubbo.config.annotation.Reference;
import com.suoron.dubbo.api.service.IUserService;
import com.suoron.dubbo.client.service.UserService;
import org.springframework.stereotype.Service;


@Service
public class UserServiceImpl implements UserService {

    @Reference(version = "1.0.0")
    public IUserService iUserService;

    @Override
    public String userLogin(String user, String password) {
        return iUserService.login(user,password);
    }
}

    Application

    package com.suoron.dubbo.client.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

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