一、创建环境

创建maven 父工程

根l

创建子工程-生产者

创建springboot子工程

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency></dependencies>

配置文件

server.port=8001
spring.application.name=nacos-provider
spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848
posure.include=*

启动类

@SpringBootApplication
@EnableDiscoveryClient
public class NacosServerApplication {public static void main(String[] args) {SpringApplication.run(NacosServerApplication.class, args);}@RestControllerpublic class TestController {@GetMapping("/hello")public String hello(@RequestParam String name) {System.out.println("invoked name = " + name);return "hello " + name;}}
}

创建子项目-消费者

配置文件


server:port: 8002spring:cloud:nacos:discovery:server-addr: 127.0.0.1:8848application:name: nacos-consumer


@SpringBootApplication
@EnableDiscoveryClient
public class NacosConsumerApplication {public static void main(String[] args) {SpringApplication.run(NacosConsumerApplication.class, args);}@Slf4j@RestControllerstatic class TestController {@AutowiredLoadBalancerClient loadBalancerClient;@GetMapping("/test")public String test() {// 通过spring cloud common中的负载均衡接口选取服务提供节点实现接口调用ServiceInstance serviceInstance = loadBalancerClient.choose("nacos-provider");String url = Uri() + "/hello?name=" + "didi";RestTemplate restTemplate = new RestTemplate();String result = ForObject(url, String.class);return "Invoke : " + url + ", return : " + result;}}}
