spring cloud sleuth 服务跟踪

作用：追踪分布式系统中服务的调用路径，分析各服务的延时时间

****************************

服务1：hello-service

********************

配置文件

application.yml

spring:
  application:
    name: hello-service
  cloud:
    consul:
      host: 192.168.57.21
      port: 8500
      discovery:
        prefer-ip-address: true

********************

cotroller 层

HelloController

@RestController
public class HelloController {
    private Logger logger= LoggerFactory.getLogger(HelloController.class);
    @RequestMapping("/hello")
    public String hello(){
        logger.info("hello service 本地调用：{}","hello world");
        return "hello world";
    }
}

****************************

服务2：hello-conusmer

********************

配置文件

application.yml

spring:
  application:
    name: hello-consumer
  cloud:
    consul:
      host: 192.168.57.21
      port: 8500
      discovery:
        prefer-ip-address: true

********************

service 层

@FeignClient(name = "hello-service",fallback = HelloServiceImpl.class)
public interface HelloService {
    @RequestMapping("/hello")
    String hello();
}

********************

serviceImpl 层

@Service
public class HelloServiceImpl implements HelloService {
    @Override
    public String hello() {
        return "本地输出 hello world";
    }
}

********************

controller 层

@RestController
public class HelloConsumerController {
    private Logger logger= LoggerFactory.getLogger(HelloConsumerController.class);
    @Resource
    private HelloService helloService;
    @RequestMapping("/consume")
    public String helloConsume(){
        logger.info("hello consumer 远程调用：{}",helloService.hello());
        logger.info("hello consumer 本地调用：{}","hello consumer");
        return "hello consumer";
    }
}

**********************

使用测试

  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70][]

********************

调用hello-conusmer的/consume接口：

hello-service

  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70 1][]

hello-consumer

  ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzkzMTYyNQ_size_16_color_FFFFFF_t_70 2][]

hello-consumer,e5282f311fdc139b,e5282f311fdc139b,false

hello-consumer：应用的名称，该值为spring.application.name的值

e5282f311fdc139b：tranceId的值，同一个请求链路的id值相同

e5282f311fdc139b：spanId，链路中的一个基本工作单元

false：默认使用抽样采集，false表示该日志不输出到相关采集服务器中，如zipkin
