将应用注册到Nacos

1.nacos2.0.4 服务注册与发现
    <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            </dependency>

2.spring-cloud-alibaba
<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>2021.0.4.0</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

3.提供服务@EnableDiscoveryClient
@SpringBootApplication
@EnableDiscoveryClient
public class NacosProviderApplication {

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

@RestController
class EchoController {
@RequestMapping(value = "/echo/{string}", method = RequestMethod.GET)
public String echo(@PathVariable String string) {
return "Hello Nacos Discovery " + string;
}
}
}

4.消费服务
@LoadBalancerClient(name = "service-provider", configuration = cuit.epoch.pymjl.config.MyLoadBalancerConfig.class)

public class MyLoadBalancerConfig {
    @Bean
    ReactorLoadBalancer<ServiceInstance> randomLoadBalancer(Environment environment,
                                                            LoadBalancerClientFactory loadBalancerClientFactory) {
        String name = environment.getProperty(LoadBalancerClientFactory.PROPERTY_NAME);
        // 随机轮询
        return new RandomLoadBalancer(loadBalancerClientFactory
                .getLazyProvider(name, ServiceInstanceListSupplier.class),
                name);
    }
}
