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

提取码:k9ba
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; }
)结果
先请求一下B项目,使其调用A
然后点击下图中的A就可以出现下图的B
总结
动手实践,加上自己的想法
