使用最新版的DUBBO构建你的微服务体系!
NACOS注册中心
-
从github下载最新版本的nacos
-
上传至服务器并解压
-
单机启动
sh startup.sh -m standalone -
nacos 控制台访问地址
http://192.168.136.129:8848/nacos,使用账号nacos/nacos登录并访问
项目框架
本次案例包含三个组件
-
公共接口层 dubbo-api
-
生产者 dubbo-provider
-
消费者 dubbo-consumer 代码目录如下：
父目录dubbo-demo
父目录主要是定义公共组件依赖，版本号，pom文件如下

在pom文件中直接依赖接口，这样生产者和消费者都可以使用了

配置文件
application.xml
-
dubbo.application.name = dubbo-provider
-
dubbo.registry.address = nacos://192.168.136.129:8848
-
dubbo.scan.base-packages=com.jianzh5.provider.service.impl
-
dubbo.protocol.port=20881
-
dubbo.protocol.name=dubbo
-
接口实现
-
@Service
-
public class HelloServiceImpl implements HelloService {
-
-
public String sayHello() {
-
return "欢迎关注微信公众号：JAVA日知录";
-
}
-
-
}
注意这里的@service引用的是org.apache.dubbo.config.annotation.Service,不要引用错了
-
启动类
-
@SpringBootApplication
-
@EnableDubbo
-
public class PrivoderBootstrap {
-
public static void main(String[] args) {
-
SpringApplication.run(PrivoderBootstrap.class, args);
-
}
-
}
需要引入@EnableDubbo注解
消费者dubbo-consumer

spring.application.name=dubbo-consumer
-
dubbo.registry.address = nacos://192.168.136.129:8848
-
server.port=9090
-
消费者
HelloController
-
/**

-
*/
-
@RestController
-
public class HelloController {
-
-
@Reference
-
private HelloService helloService;
-
-
@GetMapping("/sayHello")
-
public String sayHello(){
-
return helloService.sayHello();
-
}
-
-
}
使用@Reference注解注入HelloService
-
接口启动类
-
@SpringBootApplication
-
public class ConsumerBootstrap {
-
-
public static void main(String[] args) {
-
SpringApplication.run(ConsumerBootstrap.class, args);
-
}
-
-
}
项目启动
-
启动生产者 dubbo-provider
-
启动消费者 dubbo-consumer
-
查看nacos控制台，观察是否注册
-
访问浏览器
http://localhost:9090/sayHello查看接口返回
