springboot中不使用springcloud将dubbo和nacos整合

在Spring Boot应用中使用Dubbo和Nacos可以通过以下步骤实现：

1. 添加Dubbo和Nacos的依赖

<dependency>
    <groupId>com.alibaba.boot</groupId>
    <artifactId>dubbo-spring-boot-starter</artifactId>
    <version>2.0.0</version>
</dependency>
<dependency>
    <groupId>com.alibaba.nacos</groupId>
    <artifactId>nacos-client</artifactId>
    <version>${nacos.version}</version>
</dependency>

2. 在application.properties文件中配置Dubbo和Nacos

#Dubbo配置
dubbo.application.name=demo-provider
dubbo.registry.address=nacos://${nacos.host}:${nacos.port}
dubbo.scan.basePackages=com.example.demo.service.impl

#Nacos配置
nacos.host=127.0.0.1
nacos.port=8848

3. 创建Dubbo服务接口和实现类

public interface DemoService {
    String sayHello(String name);
}

@Service(version = "1.0.0")
public class DemoServiceImpl implements DemoService {
    @Override
    public String sayHello(String name) {
        return "Hello " + name;
    }
}

4. 在启动类上添加注解@EnableDubbo和@EnableDiscoveryClient

@SpringBootApplication
@EnableDubbo
@EnableDiscoveryClient
public class DemoProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoProviderApplication.class, args);
    }
}

5. 启动应用

6. 在Dubbo Consumer端调用服务

@RestController
public class DemoController {
    @Reference(version = "1.0.0")
    private DemoService demoService;

    @GetMapping("/hello")
    public String sayHello(@RequestParam String name) {
        return demoService.sayHello(name);
    }
}

以上就是在Spring Boot应用中使用Dubbo和Nacos的简单实现方式。
