### 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
