SpringCloud服务链路追踪Sleuth(zipkin+k

demo源码地址

一、前置条件

• 1、安装zookeeper
  zookeeper官方文档
• 2、安装kafka
  kafka官方文档
• 3、安装elasticsearch
  elasticsearch官方文档

二、搭建spring cloud应用

• 1、创建zipkin-server 应用

  • 1.1 基于zipkin-server可执行jar文件

    zipkin server

  • 1.2 基于springcloud

    • 1.2.1 添加依赖

        <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-sleuth</artifactId>
       </dependency>

       <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-sleuth-zipkin-stream</artifactId>
       </dependency>

       <dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-stream-binder-kafka</artifactId>
       </dependency>

       <dependency>
           <groupId>io.zipkin.java</groupId>
           <artifactId>zipkin-autoconfigure-ui</artifactId>
       </dependency>

       <dependency>
           <groupId>io.zipkin.java</groupId>
           <artifactId>zipkin-autoconfigure-storage-elasticsearch-http</artifactId>
           <version>2.4.1</version>
       </dependency>

• 1.2.2 在启动类上添加注解

@SpringBootApplication
@EnableZipkinStreamServer
public class ServerZipkinApplication {

   public static void main(String[] args) {
       SpringApplication.run(ServerZipkinApplication.class, args);
   }
}

• 1.2.3 在application.properties配置kafka和elasticsearch

spring.cloud.stream.kafka.binder.brokers=localhost:9092
spring.cloud.stream.kafka.binder.zkNodes=localhost:2181 

zipkin.storage.type=elasticsearch
zipkin.storage.elasticsearch.hosts=localhost:10200
zipkin.storage.elasticsearch.cluster=zipkin-test
zipkin.storage.elasticsearch.index=zipkin
zipkin.storage.elasticsearch.index-shards=1
zipkin.storage.elasticsearch.index-replicas=1

• 2、创建service-provider 应用

  • 2.1 添加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
      
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-kafka</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-stream</artifactId>
        </dependency>

• 2.2 添加服务接口

@SpringBootApplication
@RestController
/**
 * @author zhengwei
 */
public class ServiceProviderApplication {

    private static final Logger LOG = Logger.getLogger(ServiceProviderApplication.class.getName());

    public static void main(String[] args) {
        SpringApplication.run(ServiceProviderApplication.class, args);
    }

    @RequestMapping("/hi")
    public String hi() {
        LOG.log(Level.INFO, "calling trace service-provider");
        return "hi";
    }

}
 

• 2.3 在application.perperties里添加配置

server.port=8988
spring.application.name=service-provider

spring.sleuth.enabled=true
spring.sleuth.sampler.percentage = 1.0

spring.cloud.stream.kafka.binder.brokers=localhost:9092
spring.cloud.stream.kafka.binder.zkNodes=localhost:2181 

• 3、创建service-consumer应用

  • 3.1 添加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
       
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-kafka</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-stream</artifactId>
        </dependency>

• 3.2 添加HelloController

@RestController
public class HelloController {


    @Autowired
    RestTemplate restTemplate;


    @GetMapping("/hi")
    public String hi(@RequestParam String name) {
        return restTemplate.getForObject("http://localhost:8988/hi?name=" + name, String.class);
    }
}

• 3.3 在application.properties添加配置项

server.port=8765
spring.application.name=service-consumer

spring.sleuth.enabled=true
spring.sleuth.sampler.percentage = 1.0

spring.cloud.stream.kafka.binder.brokers=localhost:9092
spring.cloud.stream.kafka.binder.zkNodes=localhost:2181

• 3.4 添加应用启动类

@SpringBootApplication
public class ServiceConsumerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServiceConsumerApplication.class, args);
    }

    @Bean
    public RestTemplate getRestTemplate() {
        return new RestTemplate();
    }
}

• 三、启动应用

  • 1 启动zkipin-server服务

    ServerZipkinApplication

  • 2 启动service-provider服务

    ServiceProviderApplication

  • 3 启动service-consumer服务

    ServiceConsumerApplication

• 四、访问consumer url和zipkin server

  • 1 打开游览器访问服务消费方

    hi

  • 2 访问zipkin server

    zipkin server
