Spring Boot 2.0 + zipkin 分布式跟踪系统快速入门

原文：https://www.jianshu.com/p/9bfe103418e2

 

 

注意

Spring Boot 2.0之后，使用EnableZipkinServer创建自定义的zipkin服务器已经被废弃，将无法启动
具体可看issue
Deprecates EnableZipkinServer to explain custom servers are unsupported

开始

搭建zipkin服务器

获取最新发布的zipkin服务器，一个可执行的jar

curl -sSL https://zipkin.io/quickstart.sh | bash -s 

然后启动它

java -jar zipkin.jar 

也可以通过docker来启动

docker run -d -p 9411:9411 openzipkin/zipkin

启动后就可以在浏览器打开http://your_host:9411/zipkin/查看了。

创建两个服务

pom.xml

<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.3.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <sleuth.version>2.0.0.RELEASE</sleuth.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <!-- Sleuth automatically adds trace interceptors when in the classpath --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-sleuth</artifactId> </dependency> <!-- Sends trace data to zipkin over http (defaults to http://localhost:9411/api/v2/spans) --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-sleuth-zipkin</artifactId> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-sleuth</artifactId> <version>${sleuth.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> 

Backend.java

@EnableAutoConfiguration @RestController public class Backend { @RequestMapping("/api") public String printDate() { return new Date().toString() + " by hongxi"; } public static void main(String[] args) { SpringApplication.run(Backend.class, "--spring.application.name=backend", "--server.port=9000" ); } } 

Frontend.java

@EnableAutoConfiguration @RestController @CrossOrigin // So that javascript can be hosted elsewhere public class Frontend { @Autowired RestTemplate restTemplate; @RequestMapping("/") public String callBackend() { return restTemplate.getForObject("http://localhost:9000/api", String.class); } @Bean RestTemplate restTemplate() { return new RestTemplate(); } public static void main(String[] args) { SpringApplication.run(Frontend.class, "--spring.application.name=frontend", "--server.port=8081" ); } } 

application.properties

spring.sleuth.traceId128=true spring.sleuth.sampler.probability=1.0 

然后分别启动Backen和Frontend，在浏览器访问http://localhost:8080/，可以看到页面显示

说明调用成功，然后回到http://your_host:9411/zipkin/点击大大的那个按钮“Find Traces”即可看到调用跟踪信息。
