前言

本篇将通过搭建简单demo来讲解dubbo的使用。
官方文档

在这里插入图片描述

环境要求：

apache-zookeeper-3.5.6 :dubbo的注册中心

dubbo-2.4.9

dubbo-admin :查看服务的提供方与消费方

项目结构图

在这里插入图片描述

dubbo-api ：接口定义模块
dubbo-provider :服务提供方模块
dubbo-consumer:服务消费者模块

一、搭建项目

1、dubbo 工程

pom依赖

  146.         <module>dubbo-provider</module>
  147.     </modules>
  148. </project>

2、dubbo-api模块

pom依赖

  1. <?xml version="1.0" encoding="UTF-8"?>
  3. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  5.     <modelVersion>4.0.0</modelVersion>
  7.     <groupId>com.yi</groupId>
  8.     <artifactId>dubbo-api</artifactId>
  9.     <version>1.0-SNAPSHOT</version>
  10.     <dependencies>
  11.         <dependency>
  12.             <groupId>junit</groupId>
  13.             <artifactId>junit</artifactId>
  14.             <version>4.12</version>
  15.             <scope>test</scope>
  16.         </dependency>
  17.     </dependencies>
  18.     <properties>
  19.         <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  20.     </properties>
  21.     <build>
  22.         <plugins>
  23.             <plugin>
  24.                 <groupId>org.apache.maven.plugins</groupId>
  25.                 <artifactId>maven-compiler-plugin</artifactId>
  26.                 <version>3.8.0</version>
  27.                 <configuration>
  28.                     <source>1.8</source>
  29.                     <target>1.8</target>
  30.                 </configuration>
  31.             </plugin>
  32.         </plugins>
  33.     </build>
  34. </project>

建立TestService接口类
在这里插入图片描述

  1. package com.yi;
  3. /**
  4.  * 接口
  5.  */
  6. public interface TestService {
  8.     String SayHello(String word);
  9. }

3、dubbo-provider 模块（服务提供方）

pom依赖同父工程，并且引入dubbo-api模块

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  4.     <modelVersion>4.0.0</modelVersion>
  6.     <groupId>com.yi</groupId>
  7.     <artifactId>dubbo-provider</artifactId>

  10.     <properties>
  11.         <dubbo.version>2.6.6</dubbo.version>

  13.         <java.version>1.8</java.version>
  14.         <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  15.     </properties>
  17.     <dependencies>

在这里插入图片描述

建立TestServiceImpl实现类，对dubbo-api中接口进行实现。

① dubbo配置文件类型spring配置

② 节点：dubbo:application 就是整个项目在分布式架构中的唯一名称，可以在 name 属性中配置，另外还可以配置 owner 字段，表示属于谁。 下面的参数是可以不配置的，这里配置是因为出现了端口的冲突，所以配置。

③ 节点：dubbo:monitor 监控中心配置， 用于配置连接监控中心相关信息，可以不配置，不是必须的参数。

④ 节点：dubbo:registry 配置注册中心的信息，比如，这里我们可以配置 zookeeper 作为我们的注册中心。 address 是注册中心的地址，这里我们配置的是 N/A 表示由 dubbo 自动分配地址。或者说是一种直连的方式，不通过注册中心。

⑤ 节点：dubbo:protocol 服务发布的时候 dubbo 依赖什么协议，可以配置 dubbo、webserovice、Thrift、Hessain、http等协议。

⑥ 节点：dubbo:service 这个节点就是我们的重点了，当我们服务发布的时候，我们就是通过这个配置将我们的服务发布出去的。 interface 是接口的包路径， ref 是第 ⑦ 点配置的接口的 bean。

⑦ 最后，我们需要像配置 spring 的接口一样，配置接口的 bean。
