功能：查看服务之间的调用关系

1）启动Zipkin Server

下载Zipkin Server

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

java -jar zipkin-server-2.11.6-exec.jar

localhost:9411

2）新建项目A

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zipkin</artifactId>
        </dependency>

spring:
  zipkin:
    base-url: http://localhost:9411
  application:
    name: zipkin-service-a
 
server:
  port: 8988

@RestController
public class HelloController {
    
    @RequestMapping("/A")
    public String A(){
        return "A";
    }
}

3）新建项目B

依赖和A一样

yml中端口和名称需要修改

@RequestMapping("/B")
    public String B(){
        ResponseEntity<String> forEntity = restTemplate.getForEntity("localhost:项目A地址/A", String.class);
        String body = forEntity.getBody();
        return body;
    }
