3)、application.properties(直接将bootstrap.properties中的配置放到application.properties中)
目地址为： https://github.com/kevin-lihongmin/spring-cloud-project-kevin/tree/master/zipkin-demo，其中Zipkin服务不可用，所以可以使用单独的包进行部署。zipkin服务器包地址： https://pan.baidu.com/s/1LYpoDUJxrHoJ3Z2Z4L0yTw ，密码： ee3x。为了能够测试服务的调用链路，所以使用了三个服务 sleuth-consumer -> sleuth-provider -> sleuth-provider-provider。之前的Spring Cloud Robbin搭建中有说明，ribbon有在本地配置中添加服务端列表的方式和在注册中心或者服务者列表两种调用方式，现在把三个服务都注册到注册中心，动态进行调用，ribbon-demo详见Spring Cloud Ribbon负载均衡实现。调用大致链路如下：
一、Zipkin服务器搭建
Zipkin直接实现上面的地址下载：.jar包，直接在本地或者上传服务器后，使用 java -jar zipkin-server-2.12.9-exec.jar 进行启动，如下：
D:\Zipkin>java -jar zipkin-server-2.12.9-exec.jar

二、Sleuth服务调用链的搭建
1、基础服务搭建
在spring.start.io中添加Web、Actuator模块，然后在该项目下创建三个子模块，每个模块pom中都添加如下配置：
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-zipkin</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
</dependency>2、sleuth-provider-provider模块搭建
1)、启动类添加@EnableEurekaClient
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
/**
* 配置服务器端，启动
*
* @author kevin
* @date 2019/5/15 10:42
* @since
*/
@EnableEurekaClient
@SpringBootApplication
public class SleuthProviderProviderApplication {
public static void main(String[] args) {
SpringApplication.run(SleuthProviderProviderApplication.class, args);
}
}2)、为方便，直接在根目录下创建Controller和Service
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* 用户 Controller
*
* @author kevin
* @date 2019/5/16 9:50
*/
@RestController
public class UserProviderProviderController {
/**
* logger
*/
private static final Logger LOGGER = LoggerFactory.getLogger(UserProviderProviderController.class);
@Autowired
private UserProviderProviderService userProviderProviderService;
@GetMapping("userInfo")
public String getUserInfo() throws InterruptedException {
LOGGER.info("get userInfo");
return userProviderProviderService.getUser();
}
}import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;
/**
*
* @author kevin
* @date 2019/5/16 10:23
*/
@Service
public class UserProviderProviderService {
/**
* logger
*/
private static final Logger LOGGER = LoggerFactory.getLogger(UserProviderProviderService.class);
public String getUser() throws InterruptedException {
LOGGER.info("user Server , get User Info!");
Thread.sleep(30L);
return "{'id': 1}";
}
}3)、使用两个Spring Profile启动两台服务（直接将bootstrap.properties中的配置放到application.properties中）
application-sleuth-provider-provider-1.properties配置如下：
# 配置服务器端口 server.port = 8901 # 配置服务器名称 spring.application.name = sleuth-provider-provider eureka.instance.hostname=localhost eureka.client.registerWithEureka=true eureka.client.fetchRegistry=true spring.cloud.loadbalancer.retry.enabled = true eureka.client.healthcheck.enabled = true eureka.client.serviceUrl.defaultZone = http://127.0.0.1:8761/eureka/,\ http://127.0.0.1:8760/eureka/,http://127.0.0.1:8759/eureka/ # 上报Zipkin服务器开关 spring.zipkin.enabled=true # sleuth默认为上报为false， 现设置上报zipkin的服务地址 spring.zipkin.base-url=http://127.0.0.1:9411/ # span的采样率，默认为 0.1 spring.sleuth.sampler.probability = 1 # 为了使用速率限制采样器，请设置spring.sleuth.sampler.rate属性以选择每秒间隔接受的trace量， # 最小数字为0，最大值为2,147,483,647（最大int） spring.sleuth.sampler.rate = 10000
application-sleuth-provider-provider-2.properties配置如下：
# 配置服务器端口 server.port = 8902 # 配置服务器名称 spring.application.name = sleuth-provider-provider eureka.instance.hostname=localhost eureka.client.registerWithEureka=true eureka.client.fetchRegistry=true spring.cloud.loadbalancer.retry.enabled = true eureka.client.healthcheck.enabled = true eureka.client.serviceUrl.defaultZone = http://127.0.0.1:8761/eureka/,\ http://127.0.0.1:8760/eureka/,http://127.0.0.1:8759/eureka/ # 开启Zipkin上报 spring.zipkin.enabled=true # sleuth默认为上报为false， 现设置上报zipkin的服务地址 spring.zipkin.baseUrl = http://127.0.0.1:9411/ # span的采样率，默认为 0.1 spring.sleuth.sampler.probability = 1 # 为了使用速率限制采样器，请设置spring.sleuth.sampler.rate属性以选择每秒间隔接受的trace量， # 最小数字为0，最大值为2,147,483,647（最大int） spring.sleuth.sampler.rate = 10000
3、sleuth-provider模块搭建
1)、启动类添加@EnableEurekaClient
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.ribbon.RibbonClient;
import org.springframework.cloud.netflix.ribbon.RibbonClients;
import org.springframework.context.annotation.Bean;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
/**
* 配置服务器端，启动
*
* @author kevin
* @date 2019/5/15 10:42
* @since
*/
@EnableEurekaClient
@SpringBootApplication
@RibbonClients({@RibbonClient(name = "sleuth-provider-provider")})
public class SleuthProviderApplication {
public static void main(String[] args) {
SpringApplication.run(SleuthProviderApplication.class, args);
}
/**
* 将{@link RestTemplate} 注解成一个{@code Bean}
*
* @return {@link RestTemplate }
*/
@Bean
@LoadBalanced
public RestTemplate initRestTemplate() {
return new RestTemplate(new HttpComponentsClientHttpRequestFactory());
}
}2)、为方便，直接在根目录下创建Controller和Service
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
/**

* @date 2019/5/16 9:50
*/
@RestController
public class UserProviderController {
/**
* logger
*/
private static final Logger LOGGER = LoggerFactory.getLogger(UserProviderController.class);
@Autowired
private UserProviderService userProviderService;
@GetMapping("userInfo")
public String getUserInfo() throws InterruptedException {
LOGGER.info("get userInfo");
return userProviderService.getUser();
}
}import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;
/**
*

* @date 2019/5/16 10:23
*/
@Service
public class UserProviderService {
/**
* logger
*/
private static final Logger LOGGER = LoggerFactory.getLogger(UserProviderService.class);
/**
* 获取配置文件中的服务url
*/
@Value(value = "${config.user.provider.provider}")
private String configUserProvider;
@Autowired
private RestTemplate restTemplate;
public String getUser() throws InterruptedException {
LOGGER.info("user Server , get User Info!");
Thread.sleep(30L);
return restTemplate.getForObject(configUserProvider, String.class);
}
}3)、使用两个Spring Profile启动两台服务（直接将bootstrap.properties中的配置放到application.properties中）
application-sleuth-provider-1.properties配置如下：
# 配置服务器端口 server.port = 8903 # 配置服务器名称 spring.application.name = sleuth-provider eureka.instance.hostname=localhost eureka.client.registerWithEureka=true eureka.client.fetchRegistry=true spring.cloud.loadbalancer.retry.enabled = true eureka.client.healthcheck.enabled = true eureka.client.serviceUrl.defaultZone = http://127.0.0.1:8761/eureka/,\ http://127.0.0.1:8760/eureka/,http://127.0.0.1:8759/eureka/ config.user.provider.provider=http://sleuth-provider-provider/userInfo spring.zipkin.enabled=true # sleuth默认为上报为false， 现设置上报zipkin的服务地址 spring.zipkin.base-url=http://127.0.0.1:9411/ # span的采样率，默认为 0.1 spring.sleuth.sampler.probability = 1 # 为了使用速率限制采样器，请设置spring.sleuth.sampler.rate属性以选择每秒间隔接受的trace量， # 最小数字为0，最大值为2,147,483,647（最大int） spring.sleuth.sampler.rate = 10000
application-sleuth-provider-2.properties配置如下：
# 配置服务器端口 server.port = 8904 # 配置服务器名称 spring.application.name = sleuth-provider eureka.instance.hostname=localhost eureka.client.registerWithEureka=true eureka.client.fetchRegistry=true spring.cloud.loadbalancer.retry.enabled = true eureka.client.healthcheck.enabled = true eureka.client.serviceUrl.defaultZone = http://127.0.0.1:8761/eureka/,\ http://127.0.0.1:8760/eureka/,http://127.0.0.1:8759/eureka/ config.user.provider.provider=http://sleuth-provider-provider/userInfo spring.zipkin.enabled=true # sleuth默认为上报为false， 现设置上报zipkin的服务地址 spring.zipkin.base-url=http://127.0.0.1:9411/ # span的采样率，默认为 0.1 spring.sleuth.sampler.probability = 1 # 为了使用速率限制采样器，请设置spring.sleuth.sampler.rate属性以选择每秒间隔接受的trace量， # 最小数字为0，最大值为2,147,483,647（最大int） spring.sleuth.sampler.rate = 10000
4、sleuth-consumer模块搭建
1)、启动类添加@EnableEurekaClient
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.ribbon.RibbonClient;
import org.springframework.cloud.netflix.ribbon.RibbonClients;
import org.springframework.context.annotation.Bean;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
/**

* config-client-consumer -> config-client-provider -> config-client-provider-provider
*
* 首先所有的服务都注册到 Eureka-Server集中中心， 当所有服务都配置了maven spring-cloud-starter-sleuth
* 则默认 Spring Cloud Sleuth 已经与日志进行管理，在没有调用时，日志格式为：
* 2019-05-16 13:14:26.232 INFO [config-client-provider-provider,,,] 10768 --- [trap-executor-0] 。。。
*
* 当服务开始从web 使用链接 http://localhost:8905/userInfo 进行调用时，每个服务的日志如下：
* config-client-consumer：

# 配置服务器端口 server.port = 8905 # 配置服务器名称 spring.application.name = sleuth-consumer eureka.instance.hostname=localhost eureka.client.registerWithEureka=true eureka.client.fetchRegistry=true spring.cloud.loadbalancer.retry.enabled = true eureka.client.healthcheck.enabled = true eureka.client.serviceUrl.defaultZone = http://127.0.0.1:8761/eureka/,\ http://127.0.0.1:8760/eureka/,http://127.0.0.1:8759/eureka/ config.user.provider=http://sleuth-provider/userInfo spring.zipkin.enabled=true # sleuth默认为上报为false， 现设置上报zipkin的服务地址 spring.zipkin.base-url=http://127.0.0.1:9411/ # span的采样率，默认为 0.1 spring.sleuth.sampler.probability = 1 # 为了使用速率限制采样器，请设置spring.sleuth.sampler.rate属性以选择每秒间隔接受的trace量， # 最小数字为0，最大值为2,147,483,647（最大int） spring.sleuth.sampler.rate = 10000
5、进行服务调用，查看效果
启用服务后，在注册中看到的注册服务列表如下：
在没有进行服务调用的时候，打印日志如下：
2019-06-05 21:24:52.123 INFO [sleuth-consumer,,,] 1040 --- [ main] .s.c.n.e.s.EurekaAutoServiceRegistration : Updating port to 8905
其中 INFO [sleuth-consumer,,,] 内四个参数分别为：[服务名称，traceId, spanId, boolean类型的是否开启上报]
当在浏览器中输入 http://localhost:8905/userInfo 调用sleuth-consumer服务后，调用服务链日志如下：
