本篇文章为大家展示了如何进行springboot2.2.2集成dubbo的实现，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

最近在学习dubbo，想着作一些笔记，从来没有在csdn上面写过博客，今天献出第一次，哈哈，直接上代码

一、创建父工程

<?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> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.2.2.RELEASE</version> <relativePath/> </parent> <groupId>com.dubbo</groupId> <artifactId>demo01</artifactId> <version>1.0.0</version> <packaging>pom</packaging> <description>Spring Boot2.x 整合 dubbo</description> <modules> <module>api</module> <module>provider</module> <module>consumer</module> </modules>  <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <dubbo.version>2.7.5</dubbo.version> <curator.version>4.2.0</curator.version>  <zookeeper.version>3.4.12</zookeeper.version> </properties>   <dependencyManagement> <dependencies> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version>${dubbo.version}</version> </dependency>  <dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-recipes</artifactId> <version>${curator.version}</version> </dependency>  <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>${zookeeper.version}</version> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <scope>runtime</scope> <optional>true</optional> </dependency>  <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> </dependencies></project>

二、创建提供者与消费者共用的api

该模块没有什么好说的，提供者和消费者都需要使用的接口api，提供者和消费者都需要引入该模块

// 注解都是lombok的，真的很方便@Data@Builder@NoArgsConstructor@AllArgsConstructor(access = AccessLevel.PRIVATE)public class User implements Serializable { private Integer id; private String name; private Integer age;}

public interface UserService { User getUserById(Integer id);}

三、创建提供者

dubbo: application: # 应用名称 name: user-provider protocol: # 协议名称 name: dubbo # 协议端口 port: 20880 registry: # 注册中心地址 address: zookeeper://192.168.104.231:2181

@SpringBootApplication// 提供服务的应用必须配置此项@DubboComponentScan("com.dubbo.provider.service")public class ProviderApplication { public static void main(String[] args) { SpringApplication.run(ProviderApplication.class, args); }}

@Component// 该service是org.apache.dubbo.config.annotation.Service@Servicepublic class UserServiceImpl implements UserService { @Override public User getUserById(Integer id) { User user = User.builder() .id(id) .name("张三") .age(20 + id) .build(); return user; }}

四、创建消费者

# 端口server: port: 8081dubbo: application: name: user-consumer protocol: name: dubbo port: 20880 registry: address: zookeeper://192.168.104.231:2181

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

@RestController@RequestMapping("/user")public class ConsumerController { @Reference private UserService userService; @GetMapping("/{id}") public User getUserById(@PathVariable int id) { return userService.getUserById(id); }}

五、启动并访问

启动provider

启动consumer

浏览器访问：http://localhost:8081/user/4
