干翻Dubbo系列第三篇：Dubbo术语与第一个应用程序

前言

不从恶人的计谋，不站罪人的道路，不坐亵慢人的座位，惟喜爱耶和华的律法，昼夜思想，这人便为有福！他要像一棵树栽在溪水旁，按时候结果子，叶子也不枯干。凡他所做的尽都顺利。

如何找到孙帅本人

本文内容整理自《孙哥说Dubbo系列视频课程》，老师实力十分雄厚，B站搜孙帅可以找到本人，视频中有老师的微信号。

一：代码结构和术语解释

provider 功能提供者
consumer 功能消费者
commons-api 通用内容 entity+service接口
registry 注册中心

注册中心的作用就是管理provider和consumer的集群的，方便后续的水平拓展。可以进行健康检查，检查provider是否可以正常健康，保证服务提供正常强大的服务。

二：Dubbo直连第一个Provider程序

1：Dubbo通用API和实体编写

@Data
@ToString
@NoArgsConstructor //
@AllArgsConstructor
public class User implements Serializable {
    private String name;
    private String password;
}


public interface UserService {
    public boolean login(String name, String password);
}

在这里插入图片描述

2：Dubbo中Provider编写

public class UserServiceImpl implements UserService {
    @Override
    public boolean login(String name, String password) {
        System.out.println("UserServiceImpl.login name " + name + " password " + password);
        return false;
    }
}

3：Dubbo中Provider配置网络通信

在XML当中配置Dubbo相关标签，保证可以跨虚拟机调用。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">
	
	//给Dubbo应用起个名字
    <dubbo:application name="dubbo-02-provider"/>
	//指定通信网络协议和通信使用的端口。
	//dubbo是Dubbo默认的协议和默认的端口20880
    <dubbo:protocol name="dubbo" port="20880"/>
	
	//Spring在Provider当中帮我们创建对象
    <bean id="userService" class="com.suns.service.UserServiceImpl"/>
	//把这个对象发布成一个Dubbo服务，让Dubbo服务可以调用。ref指向一个对象。
    <dubbo:service interface="com.suns.service.UserService" ref="userService"/>
</beans>

两个疑问：
1：为毛第一个不用SpringBoot?
SpringBoot封装的太厉害了。使用SpringBoot封装的太厉害了，我们打个注解就好了，Spring能让我们看到大致的运行过程。

2：两个shema问题
在这里插入图片描述
当我们在xml当中预制这个标签的时候，会提示这两个schema标签，我们注意使用dubbo的那个。

3：这个标签的作用
这个标签的作用就是给Dubbo的应用起个名字，我们这个provider是一个Dubbo应用。将来这个名字会被注册中心管理，必须唯一，每一个dubbo的项目，消费者或者生产者都必须得有这个名字。

4：Provider当中创建一个启动类

public class ProviderMain {
    public static void main(String[] args) throws InterruptedException {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-provider.xml");
        applicationContext.start();
        
        //让主线程在这里阻塞。
        new CountDownLatch(1).await();
    }
}

最核心的是最后一行，最后一行一出现，代表我们的Dubbo服务一定启动好，可以对外提供服务了

关键日志分析：

22:45:04.559 [main] INFO org.apache.dubbo.config.ServiceConfig -  [DUBBO] Export dubbo service com.suns.service.UserService to url dubbo://192.168.8.1:20880/com.suns.service.UserService

Export 导出、暴露 Dubbo服务这个接口到如下的URL地址：dubbo是协议名：ip端口号，后边是具体的接口地址。

Provider开发到此结束。
