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
目前创新互联建站已为1000多家的企业提供了网站建设、域名、雅安服务器托管、成都网站托管、企业网站设计、青山湖网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。
一、创建父工程
<?xml version="1.0" encoding="UTF-8"?>4.0.0 org.springframework.boot spring-boot-starter-parent 2.2.2.RELEASE com.dubbo demo01 1.0.0 pom Spring Boot2.x 整合 dubbo api provider consumer UTF-8 UTF-8 1.8 2.7.5 4.2.0 3.4.12 org.apache.dubbo dubbo-spring-boot-starter ${dubbo.version} org.apache.curator curator-recipes ${curator.version} org.apache.zookeeper zookeeper ${zookeeper.version} org.springframework.boot spring-boot-devtools runtime true org.projectlombok lombok true
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
<?xml version="1.0" encoding="UTF-8"?>demo01 com.dubbo 1.0.0 4.0.0 api
// 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
<?xml version="1.0" encoding="UTF-8"?>4.0.0 com.dubbo 1.0.0 demo01 com.dubbo provider 0.0.1-SNAPSHOT provider Demo project for Spring Boot org.springframework.boot spring-boot-starter-web org.apache.dubbo dubbo-spring-boot-starter org.apache.curator curator-recipes org.apache.zookeeper zookeeper com.dubbo api 1.0.0 org.springframework.boot spring-boot-starter-test test org.junit.vintage junit-vintage-engine org.springframework.boot spring-boot-maven-plugin
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
@Service
public 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
<?xml version="1.0" encoding="UTF-8"?>4.0.0 com.dubbo 1.0.0 demo01 com.dubbo consumer 0.0.1-SNAPSHOT consumer Demo project for Spring Boot org.springframework.boot spring-boot-starter-web org.apache.dubbo dubbo-spring-boot-starter org.apache.curator curator-recipes org.apache.zookeeper zookeeper com.dubbo api 1.0.0 org.springframework.boot spring-boot-starter-test test org.junit.vintage junit-vintage-engine org.springframework.boot spring-boot-maven-plugin
# 端口 server: port: 8081 dubbo: application: name: user-consumer protocol: name: dubbo port: 20880 registry: address: zookeeper://192.168.104.231:2181
@SpringBootApplication
public 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
先启动provider，启动结果如下
启动consumer，启动结果如下
浏览器访问：http://localhost:8081/user/4
好了，到此就完成了最基本的springboot与dubbo的整合,更多的dubbo的api请查阅 dubbo官方文档
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持创新互联。
