Spring Cloud Sleuth (zipkin组件)(Finchley版本)

一时失言乱红尘 2023-02-12 11:19 4阅读 0赞

**1.构建服务zipkin**

在spring Cloud为F版本的时候，已经不需要自己构建Zipkin Server了，只需要下载jar即可，下载地址：

https://dl.bintray.com/openzipkin/maven/io/zipkin/java/zipkin-server/

下载并启动该服务。

**登陆：http://localhost:9411 可以查看**

2.eurka-server服务先启动，服务的注册中心

**3.实现服务a**

**\*\*\*\*\*\*\*\*\*服务 eureka-service-a\*\*\*\*\*\*\*\*\*\***

**application.yml 注意这里的zipkin的服务中心是**[http://localhost:9411][http_localhost_9411] 而不是[http://localhost:9411/zipkin/][http_localhost_9411_zipkin] 被这个坑了好一会.

server:
      port: 8770
    
    spring:
      application:
        name: eureka-service-a
      zipkin:
        base-url: http://localhost:9411
    
    eureka:
      client:
        serviceUrl:
          defaultZone: http://localhost:8761/eureka/

IndexController

package com.cxb.springcloud.web;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.client.RestTemplate;
    
    
    @RestController
    public class IndexController {
    
        @Autowired
        private RestTemplate restTemplate;
    
        @GetMapping("/getInfo")
        public String get() {
            return "service a";
        }
    
        @RequestMapping("/call")
        public String callService(){
            return restTemplate.getForObject("http://EUREKA-SERVICE-B/getInfo", String.class);
        }
    }

启动类EurekaServiceAApplication，注意这里的@EnableDiscoveryClient注解要加上，不然后面报错No instances available for EUREKA-SERVICE-B，被这个也坑了好一会0.0

package com.cxb.springcloud;
    
    import brave.sampler.Sampler;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    import org.springframework.cloud.client.loadbalancer.LoadBalanced;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    import org.springframework.context.annotation.Bean;
    import org.springframework.web.client.RestTemplate;
    
    @SpringBootApplication
    @EnableEurekaClient
    @EnableDiscoveryClient
    public class EurekaServiceAApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(EurekaServiceAApplication.class, args);
        }
    
        @Bean
        @LoadBalanced
        public RestTemplate getRestTemplate(){
            return new RestTemplate();
        }
    
        @Bean
        public Sampler defaultSampler() {
            return Sampler.ALWAYS_SAMPLE;
        }
    }

启动服务a。

**4.实现服务b,跟服务a基本一样**

**\*\*\*\*\*\*\*\*\*服务 eureka-service-b\*\*\*\*\*\*\*\*\*\***

            return restTemplate.getForObject("http://EUREKA-SERVICE-A/getInfo",String.class);
        }

EurekaServiceBApplication启动类

package com.cxb.springcloud;

        @Bean
        public Sampler defaultSampler() {
            return Sampler.ALWAYS_SAMPLE;
        }
    }

启动服务b。

最后测试：服务注册成功。
