zipkin+micrometer实现链路追踪

news 来源：原创 2025/5/21 11:39:33

背景：学习微服务的时候，由于所有的依赖都是用的最新的，导致学习zipkin+micrometer实现链路追踪时项目报错。为此我重新建了一下项目，把不相关的依赖全部去掉了，用到的依赖尽量用到了最新版本

一、项目所有文件截图（精简版）

二、主目录pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>

import org.springframework.core.env.Environment;
import org.springframework.web.client.RestTemplate;@Configuration
@LoadBalancerClient(value = "cloud-payment-service",configuration = RestTemplateConfig.class)
public class RestTemplateConfig {@Bean@LoadBalanced //使用@LoadBalanced注解赋予RestTemplate负载均衡的能力public RestTemplate restTemplate() {return new RestTemplate();}@BeanReactorLoadBalancer<ServiceInstance> randomLoadBalancer(Environment environment,LoadBalancerClientFactory loadBalancerClientFactory) {String name = environment.getProperty(LoadBalancerClientFactory.PROPERTY_NAME);return new RandomLoadBalancer(loadBalancerClientFactory.getLazyProvider(name, ServiceInstanceListSupplier.class), name);}
}

@EnableFeignClients//启用feign客户端,定义服务+绑定接口，以声明式的方法优雅而简单的实现服务调用
public class Main80 {public static void main(String[] args) {SpringApplication.run(Main80.class, args);}
}
