服务链路追踪(Spring Cloud Sleuth) sping boot 集成 zipkin 的 Demo（一）
一、首先建立四个项目
1、服务端 项目名称 ZipkinServer
pom文件如下
其中主要是zipkin的依赖
4.0.0
com.zipkinServer
ZipkinServer
0.0.1-SNAPSHOT
jar
ZipkinServer

org.springframework.cloud
spring-cloud-dependencies
${spring-cloud.version}
pom
import
org.springframework.boot
spring-boot-maven-plugin
application.properties 文件如下
server.port=11008
spring.application.name=ZipkinServer在启动主方法类中加上注解 @EnableZipkinServer，声明这是一个zipkin的服务端
package com.zipkinServer.ZipkinServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import zipkin.server.EnableZipkinServer;
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServerApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServerApplication.class, args);
}
}2、客户端A 项目名称 ZipkinHello
pom文件如下， 同样主要是zipkin的依赖
4.0.0
com.ZipkinHello
ZipkinHello
0.0.1-SNAPSHOT
jar
ZipkinHello
Demo project for Spring Boot

spring.application.name=ZipkinHello集成日志工具logback往ELK输出所以logback.xml文件如下

程序入口代码
package com.zipkinServer.ZipkinServer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@SpringBootApplication
@RestController
public class ZipkinHelloApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinHelloApplication.class, args);
}
private final static Logger logger = LoggerFactory.getLogger(ZipkinHelloApplication.class);
private final static Logger kibanaLogger = LoggerFactory.getLogger("kibanaLog");
@Autowired
private RestTemplate restTemplate;
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
@RequestMapping("/sayhello")
public String sayhello() {
logger.info("----sayhello----");
kibanaLogger.info("======kibana:sayhello======");
ResponseEntity responseEntity = restTemplate.getForEntity("http://localhost:8999/helloToGoodBye?name={1}", String.class, "8989张三");
return responseEntity.getBody();
}
@RequestMapping("/goodBye")
public String goodBye(String name) {
logger.info("----goodBye----");
kibanaLogger.info("======kibana:goodBye======");
return "goodBye,"+name;
}
}
第一个sayHello是调用服务的发起者
第二个goodBye服务是被调用方
客户端A ZipkinHello 完毕
3、客户端B ZipkinUnicom 该服务作为 A C 服务的中转服务存在 具体设置与客户端A类似主要取别如下
application.properties文件
server.port=8999
spring.zipkin.base-url=http://localhost:11008
spring.application.name=ZipkinUnicom程序代码
package com.zipkinServer.ZipkinServer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@SpringBootApplication
@RestController
public class ZipkinUnicomApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinUnicomApplication.class, args);
}
private final static Logger logger = LoggerFactory.getLogger(ZipkinUnicomApplication.class);
private final static Logger kibanaLogger = LoggerFactory.getLogger("kibanaLog");
@Autowired
private RestTemplate restTemplate;
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
@RequestMapping("/helloToGoodBye")
public String helloToGoodBye(String name) {
logger.info("====helloToGoodBye====");
kibanaLogger.info("=========kibana:helloToGoodBye=========");
ResponseEntity responseEntity = restTemplate.getForEntity("http://localhost:8988/hello?name={1}", String.class, name);
return responseEntity.getBody();
}
@RequestMapping("/goodByeToHello")
public String goodByeToHello(String name) {
logger.info("====goodByeToHello====");
kibanaLogger.info("=========kibana:goodByeToHello=========");
ResponseEntity responseEntity = restTemplate.getForEntity("http://localhost:8989/goodBye?name={1}", String.class, name);
return responseEntity.getBody();
}
}
4、客户端C ZipkinGoodBye
application.properties代码如下
server.port=8988
spring.zipkin.base-url=http://localhost:11008
spring.application.name=ZipkinGoodBye程序代码如下
package com.zipkinServer.ZipkinServer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@SpringBootApplication
@RestController
public class ZipkinGoodByeApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinGoodByeApplication.class, args);
}
private final static Logger logger = LoggerFactory.getLogger(ZipkinGoodByeApplication.class);
private final static Logger kibanaLogger = LoggerFactory.getLogger("kibanaLog");
@Autowired
private RestTemplate restTemplate;
@Bean
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
@RequestMapping("/sayGoodBye")
public String sayGoodBye() {
logger.info("----sayGoodBye----");
kibanaLogger.info("=========kibana:sayGoodBye=========");
ResponseEntity responseEntity = restTemplate.getForEntity("http://localhost:8999/goodByeToHello?name={1}", String.class, "8988李四");
return responseEntity.getBody();
}
@RequestMapping("/hello")
public String sayHello2(String name) {
logger.info("----hello----");
kibanaLogger.info("=========kibana:hello=========");
return "hello,"+name;
}
}
二、启动这四个服务
启动顺序为 ZipkinServer -->ZipkinHello --> ZipkinUnicom --> ZipkinGoodBye 要按顺序启动
启动后打开http://localhost:11008/可看到界面
三、访问地址http://localhost:8988/sayGoodBye，http://localhost:8989/sayhello
可以看到返回信息界面
四、查看控制台打印的日志
三个客户端服务分别输出下列日志
2018-11-09 17:45:53.953[3b823e4538d5bd90,3b823e4538d5bd90] [http-nio-8989-exec-4] INFO c.zipkinServer.ZipkinServer.ZipkinHelloApplication - ----sayhello----
2018-11-09 17:45:53.958[3b823e4538d5bd90,053423295201b4c4] [http-nio-8999-exec-4] INFO c.z.ZipkinServer.ZipkinUnicomApplication - ====helloToGoodBye====2018-11-09 17:45:53.966[3b823e4538d5bd90,dce48c58b696242f] [http-nio-8988-exec-5] INFO c.z.ZipkinServer.ZipkinGoodByeApplication - ----hello----因为logback服务定义的输出日志格式是
[%X{X-B3-TraceId:-},%X{X-B3-SpanId:-}] 的部分都是“3b823e4538d5bd90” 表明它是一次调用的一个过程这样就能通过日志查看服务的调用情况了
