这是一个基于Dubbo+Zookeeper 的 RPC 远程调用框架 demo，希望读者可以通过这篇文章大概能看懂这一个简单的框架搭建。

Dubbo是阿里巴巴公司开源的一个高性能优秀的服务框架，使得应用可通过高性能的 RPC 实现服务的输出和输入功能，可以和Spring框架无缝集成。

Dubbo是一款高性能、轻量级的开源Java RPC框架，它提供支持DZ源码了三大核心能力：面向接口的远程 *** 调用，智能容错和负载均衡，以及服务自动注册和发现。微信搜索 web_resource 关注获取更多推送

provider：暴露服务的服务提供方

consumer：调用远程服务的服务消费方

registry：服务注册于发现的注册中心

monitor：统计服务调用次数和调用时间的监控中心

container：服务运行容器

一、dubbo-provider（服务提供方）

1、Java Bean

为什么要实现Serializable接口支持DZ源码？当我们需要把对象的状态信息通过网络进行传输，或者需要将对象的状态信息持久化，以便将来使用时都需要把对象进行序列化。

使用了Lombok，它能通过注解的方式，在编译时自动为属性生成构造器、getter/setter、equals、hashcode、toString *** 。

@Datapublic class UserInfo implements Serializable { private String account; private String password;}

2、UserService

服务提供方 暴露的服务，将注册到zookeeper上。

public interface UserService { // 定义用户登录的api UserInfo login(UserInfo user);}

3、UserServiceImpl

服务提供方暴露的服务对应的实现类。

@Component@Service(interfaceClass = UserService.class)public class UserServiceImpl implements UserService { public UserInfo login(UserInfo user) { UserInfo reUser = new UserInfo; reUser.setAccount("登录的账号为:"+user.getAccount); reUser.setPassword("登录的密码为:"+user.getPassword); return reUser; }}

4、DubboProviderApplication@SpringBootApplication@EnableDubboConfiguration // 启用dubbo自动配置public class DubboProviderApplication { public static void main(String[] args) { SpringApplication.run(DubboProviderApplication.class, args); }}

5、pom.xml<?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.boot.dubbo.demo</groupId> <artifactId>dubbo-provider</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>dubbo-provider</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.6.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--Dubbo依赖--> <dependency> <groupId>com.alibaba.spring.boot</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>2.0.0</version> </dependency> <!--自动生成getter，setter，equals，hashCode和toString等等--> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.20</version> <scope>provided</scope> </dependency> <!--Zookeeper客户端--> <dependency> <groupId>com.101tec</groupId> <artifactId>zkclient</artifactId> <version>0.10</version> </dependency> <!--Zookeeper依赖，排除log4j避免依赖冲突--> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.10</version> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </exclusion> <exclusion> <groupId>log4j</groupId> <artifactId>log4j</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build></project>

二、dubbo-consumer（服务消费方）

1、UserController@RestControllerpublic class UserController { @Reference // 引用dubbo服务器提供服务器接口 private UserService userService; @GetMapping("/login") public UserInfo login(UserInfo userInfo) { return userService.login(userInfo); }}

2、DubboConsumerApplication@SpringBootApplication@EnableDubboConfiguration // 启用dubbo自动配置public class DubboConsumerApplication { public static void main(String[] args) { SpringApplication.run(DubboConsumerApplication.class, args); }}

4、application.ymlspring: dubbo: application: name: dubbo-consumer protocol: name: dubbo port: 20880 registry: address: zookeeper://127.0.0.1:2181server: port: 8081

三、Zookeeper安装配置

Zookeeper集群环境搭建:

四、项目启动

五、查看Zookeeper服务注册情况

六、通过浏览器发送请求（dubbo-provider的服务注册到Zookeeper上，dubbo-consumer消费者可以调用注册的服务）。

到此，rpc远程调用服务通了！感兴趣的话可以去学习下。
